If Bluetooth is selected, the device searches for a Bluetooth connection before displaying the menu.
If Wi-Fi is selected, the device searches for a Wi-Fi connection before displaying the menu.
Turn the knob without selecting an item to enter the “Wi-Fi config” menu.
The baud rate and Modbus address must be the same as in the PC/Android app.
When you change online mode to BT or Wi-Fi, please save first. The next step will allow you other settings.
Please note: The pin code is stored in the BT module itself, not in the internal memory of the PSU.
BT connected – it means the BT board is found. Regardless of connecting to PC/Android device.
“BT Debug” starts when you save the menu in BT mode. This allows you to see the AT commands sent to the BT module. Whites are commands and greens are answers.
Select Protocol you need.
1) RIDEN to communicate with
- DPSmaster PC app (USB, BT, Wi-fi)
- Riden PC app (USB, BT)
- Riden Android app (BT)
- USB, BT – Modbus RTU Master
- Wi-Fi Modbus TCP client
2) WUZHI to communicate with
- Wuzhi PC app (USB,BT)
- Wuzhi Android app (Wi-Fi)
- Wi-Fi – TCP server
Attention: The Wi-Fi SMART config for RIDEN and WUZHI protocols are fundamentally different!
Instead of a regular one, you can use any USB-UART or UART-RS485 converters.
You can use BC-04 (or JDY-31) bluetooth modules instead of stock ones. Be careful with its supply voltage.
You can use ESP-12 modules (with ESP-8266) without prior programming instead of stock ones. Be careful with its supply voltage.
Wi-Fi config menu
In station mode, you can connect manually by entering the SSID and password. Or you can use Wi-Fi SMART config (see below).
In access point mode, the default radio channel is 1. If you want to select a different channel (01..14), enter numbers at the beginning of the access point’s SSID. Example: 06Zyxel1 – will work on channel 06.
Hold down the “V-SET” button after turning on the power during the logo screen.
If Wi-Fi is selected, the device searches for a Wi-Fi connection before displaying the menu.
Turn the knob without selecting an item to enter the “Communication” menu.
IP – is the IP address of the device on the local wi-fi network.
Mode – Station or Access Point.
Mode change – Select “Yes” if you want to change the mode.
SSID. In station mode, this is the name of the access point you are connected to. Otherwise, the name of the access point. Maximum 16 characters.
Pswd – password. Maximum 16 characters. You cannot see the password in station mode if the Wi-Fi is already connected.
TCP – TCP server IP address for WUZHI protocol. Not used by the RIDEN protocol.
Wi-Fi SMART config - protocol WUZHI
Launch android wuzhi app on your gadget. Make sure it’s connected to your local Wi-Fi network.
Hold down the “P-SET” button after turning on the power during the logo screen.
When the Wi-Fi Smart Config screen (Figure 1) appears, select “network settings” from the Android app menu.
Wait for TCP to change from 000.000.000.000 to 192.168.xxx.xxx. (Figure 2)
Then click “NEXT” on the Android app and enter the password for your local Wi-Fi network. Click “CONFIRM“.Wait for the SMART Config to finish (Figure 3).
Wi-Fi SMART config - protocol RIDEN
Launch ESPTouch app on your Android or Apple gadget. Make sure it’s connected to your local Wi-Fi network. Choose “EspTouch” not “EspTouch V2”.
Enter the password for your local Wi-Fi network. Device Count = 1. Broadcast.
Hold down the “P-SET” button after turning on the power during the logo screen.
When the Wi-Fi Smart Config screen (Figure 1) appears, click “CONFIRM” in the Android app.
Wait for the SMART Config to finish (Figure 2).
Modbus communication protocol
The basic data of the communication protocol is the same as the stock Chinese protocol of DPS devices. Additional data has been added. Read more here.
Calibration
When the power output is on, press and hold “P-SET” button for 3 seconds.
The calibration procedure is pretty straightforward. You only need a multimeter and an external power supply. Do not use a load during calibration.
The basic principle of calibration is to define two points – LOW point and HIGH point. For example, we can calibrate the input voltage at 6 V (low point) and 25 V (high point). It’s enough.
The low and high points are already preset in the device, but you must enter the correct values displayed on the multimeter.
Navigate menu item by pressing arrow up and down buttons. To start item press “P-SET” button. When the item blinking set correct value by the knob. To apply the value push the rotary knob for 3 second. The applied value goes blue. To store the changes select “Save?” – Yes and then “Exit”.
To achieve greater accuracy, repeat the calibration procedure 2 or 3 times.
If something goes wrong, you can restore the default settings at any time.
NOTE. Select I out H current value suitable for the maximum current of the multimeter.
If the calibration doesn’t work – READ HERE
VALUE-ADC-DAC
This page is mainly for information. Do not manually change the values on this page unnecessarily.
If you have a revision with a different hardware version and the calibration values differ significantly from the default ones, you can send me a photo of the VALUE-ADC-DAC page with a description of your model so that I can use your data in the next firmware revisions. admin@profimaxblog.ru
Firmware Update via USB/UART
Press “ON/OFF” button after enabling power during the logo screen to enter the “Update mode”.
When the screen goes black, you can upload new firmware using STM32CubeProgrammer (or ST’s old Flasher).
Connect USB cable to PC, start STM32CubeProgrammer, select UART, then correct COM port (baudrate 38400, with parity “EVEN“), click “Connect” and start programming.
NOTE: The update doesn’t work via bluetooth because your BT whistle on PC can’t transmit “EVEN ” parity. The update doesn’t work via Wi-Fi.
Also you can update firmware using DPSmaster application.
Connecting additional modules
It is possible to connect an external digital temperature sensor and an additional cooling fan.
DPSmaster
DPSmaster is Windows PC application for communicate with Digital Power Suplly via USB or Bluetooth or Wi-Fi:
- WZ5005
- WZ6012
- DPS3003
- DPS3005
- DPS3012
- DPS5005
- DPS5015
- DPS5020
- DPS8005
Single application for all models. The application is 5Mb executable file without installation and any middleware. It works with stock and alternative firmware.
A WARNING ABOUT CHARGING BATTERIES
Connecting any rechargeable batteries directly to the output of the unit can crash the WZ device !!!
- In case of polarity reversal – 100% failure of any WZ model.
- When the output voltage of the power supply is turned off, the voltage from the battery will flow back to the power supply. This could damage it.
- These features are associated with the circuitry of the power supplies and do not depend on the firmware.
- To avoid the above charging problems, use an additional diode as shown in the figure below. Consider the amperage and voltage drop across the diode when charging.
- If you find it difficult to understand the above problems, do not charge the batteries using WZ power supplies, use specialized chargers instead.

Как по мне, блоки WZ намного интереснее, чем DPS. Это и размер и дизайн. Экранчик побольше и поярче. Процессор помощнее и побыстрее. Приятные мягкие кнопки с подсветкой. Звуковой сигнал. Два порта, можно например подключить сразу блютуз и усб, выбирая их из меню. И ещё эти блоки идеально помещаются в старые советские блоки питания.
Есть проблемка с пульсациями выходного напряжения, но с этим ещё не разбирался. -

>У меня вопрос. Может STM32 софтово перегрузиться в bootloader и передать какие-то данные туда?
Я не понял вопроса. Куда передать данные?
А перегрузиться программно в бутлоадер конечно можно. Что прошивка и делает, при нажатии нужных кнопок.
Через бутлоадер можно работать так-же как и через ST-Link.
Через бутлоадер можно как залить, так и прочитать прошивку. Прочитать можно, если не выставлена защита от чтения в Option Bytes.
Если защита была, её тоже можно снять через бутлоадер. Но в этом случае вся прошивка сотрется. -
-
>Тогда вопрос. Зачем нам при первой прошивке ST Link?
В изделиях Riden DPS3003…DPS5015…DPS8005, как и в изделиях Wuzhi WZ, никаких намёков на возможность обновления прошивки не обнаружено. Возможно там есть какая-то скрытая неопубликованная возможность, но мы об этом не знаем. В официальных опубликованных протоколах связи нет такого регистра, при записи которого происходит переход в бутлоадер.
Поэтому нам и нужен ST-Link для смены прошивки.
В своих прошивках я использую расширенный протокол связи, я дополнил протокол Riden, в том числе есть регистр при записи которого происходит переход в бутлоадер. За счет этого появилась возможность обновления прошивки.
В изделиях WZ оказалось ещё сложнее, так как там используемый стандартным бутлоадером USART1 занят вай-фаем. Пришлось писать свой собственный бутлоадер, который работает на USART3, к которому у WZ подключается адаптер USB. -

Recently I got original firmware from WZ6012.
I shared original firmware.You need stlink and eeprom writer.
First you flashed original firmware to STM32.
And then you need to write eeprom data to 24C02N.After WZ6012 booting, you should initialize data in setting menu.
Menu name: use “reset:Y” -

Эх….
А я постоянно заряжаю аккумулятор.
Нажимаю ON/OFF, и смотрю напряжение аккумулятора на экранчике.Иногда идут выбросы на источник питания, когда понижаю напряжение ручкой, и на блокн даже вентилятор ненадолго останавливается. Но в остальном все работает штатно. Ничего не сгорает (тьфу, тьфу), и даже не перезагружается WEGE WZ6012, то есть, питание не прерывается.
А оно точно опасно?
И да, если отключаю блок питания из розетки, получается, что он питается от аккумулятора. И даже у питающей блока питания (сорри), зелёная лампочка горит.

Подключение АКБ напрямик к выходу – на ваш страх и риск. Может и не случится ни чего. А может случиться как тут https://youtube.com/shorts/3TZ0kz89M-o?

Приветствую!
Собираюсь считывать по USB автономным логгером Uout, Iout и OnOff, какие подводные камни могут быть без включения Lock кроме отсутствия автоопределения обрыва связи?
Я правильно понимаю, если в процессе работы(заряда) я не меняю USET, ISET и MEM, то “Автосохранение” не происходит, и конфликтов с кнопками быть не должно?Why do we need LOCK = 1 at the beginning of the session – https://profimaxblog.ru/modbus-communication-protocol/
-

Здравствуйте!
Если только считывать Uout, Iout и OnOff, то “Автосохранения” не случится и конфликта с кнопками не будет.
Обрыв связи определяется не состоянием регистра LOCK, а наличием запросов от мастера (неважно запрос на запись или чтение). Подводных камней быть не должно, если мастер посылает запрос только после того как получил ответ. Если нет возможности контролировать поступление ответа, тогда нужно делать задержку между запросами не менее 100 миллисекунд.
Я не вижу взаимосвязи между форматом лог-файла и выбором связи USB или Bluetooth.
Скорее всего есть опасность создания файла слишком большого размера.
Если на смартфоне пользователь вряд-ли будет долго вести лог, то на настольном компьютере пользователь может включить лог на несколько суток, не подозревая что создается гигантский файл, который потом будет невозможно открыть. -

I can’t manage to connect to the ST.
Is there a way to hold the device in reset while connecting?Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

Hello!
ST-Link perfectly connects with the MCU when it is in run mode. No need any reset mode.
Use external power for WZ device as usual. Do not connect power via the ST-link. Update your ST-link firmware.-
>> Use external power for WZ device as usual. Do not connect power via the ST-link. Update your ST-link firmware.
I did all that – maybe the ST-Link is broken? But then it wouldn’t have been recognized by the STM32 programmer in the first place…I bought this clone from china 🙂

Perhaps new versions of CubeProgrammer conflict with Chinese ST-Link clones. Try to find older versions of CubeProgrammer. Or find an already proven ST-Link in your city. I’ve seen Chinese clones that don’t work at all.

Okay, different plan…
I found a J-Link Plus laying around so I’m using that instead 🙂Can you tell me which chip exactly is used in a WZ6012 (see attached screenshot)?
Also do I need any more information?Thanks for your help!
