Did you do it in KiCAD? Is it on github?

Yes - it's made in KICAD. This is my second attempt to create a board, the first had some errors. Not on GitHub. I can share.

I found JLCPCB stocks an ESP32 (ESP32-WROOM-32E) module that they can solder directly to the board for about $3 :) They also have an ESP8266 module but that is out of stock. So I think I will make a variant of the Nissan Leaf adapter board that takes this and as I understood the web interface runs ...

can you tell about it in more detail?

Hello everyone! Anyone have any success in getting data from atmega to wemos via the web interface? Atmega sends data to the port monitor, wemos sends the "params" command correctly and it is visible in pytty. I connect uart esp and atmega - there are no parameters in the web interface ......

Fine! It worked for me. Good news! Just the one line of code needed? Added this line: #include <ESP8266WiFi.h> and this is: #ifdef WIFI_IS_OFF_AT_BOOT enableWiFiAtBootTime(); // can be called from anywhere with the same effect #endif https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/gene...

It might be an easy fix but I don't have any hardware on hand to test right now.

Fine! It worked for me.

if you've cloned from my repo, grab the latest update and try again, I've just made a change.. Just note, I'm not sure if anyone uses the web interface, I went a different direction with charging. Thanks to! This update helped, everything compiles and loads! It remains to overcome the problem with ...

Hello members of the forum! Someone can tell you how to solve this problem - compiling the Platformio web interface gives the following error: lib/avr/IntelHexParse.cpp: In member function 'byte* IntelHexParse::GetData(byte*, int)': lib/avr/IntelHexParse.cpp:86:1: error: no return statement in funct...

What was the problem with the ebay chips? Completely dead or strange behaviour? In my case, all the microcircuits were in use with firmware on board and from different factories. I was able to flash 2 microcontrollers via SWD. In two, the SWD ports were occupied by the application and had to be rem...

You can get some off ebay, though I don't know if they're any good. Hello! I will share my experience of buying STM microcontrollers on eBay. I bought 6 stm32 microcontrollers and 3 atmegs from https://www.ebay.com/usr/longsheng-electronic. Upon opening the parcel, microcontrollers with markings fr...

Strange - the maximum that I can overclock the engine on this firmware is 6 hz 88 rpm. https://openinverter.org/parameters/view.html?id=20 In the inverter configuration, the previous firmware is 4.97.R-sine. She works! Everything worked out! Changed Potmode settings to DualChannel and it all worked...

I experimented with two Leaf inverters with Johannes boards version 3. On the Main inverter (let's call it MG2) an asynchronous motor is connected, on the second inverter (let it be MG1) the Leaf EM57 motor. Everything worked. MG1 starts to rotate from the beginning of the accelerator stroke, and th...

Hello! Tell me - what am I doing wrong? I'm flashing the ESP 8266 module using the "ESP 8266 flasher" program from here: https://github.com/dimecho/Open-Inverter-Dashboard/releases/download/1.0/Open.Inverter.Dash.zip I specify the address 0x000000 for flash- WeMos-D1.bin and 0x100000 for f...

Согласен, посмотрел детально фото https://openinverter.org/wiki/images/7/ ... ng_Map.png так и есть.

Ты чего-то явно не замечаешь. Принцип построения наверное всех 3-х фазных преобразователей частоты одинаков. С микроконтроллера выходит 6 выводов управления фазами, По 2 на фазу - один вывод управляет ключом задающим положительный потенциал на фазе - второй отрицательным потенциалом. И так в каждой ...

Yahha777

Нет - С тремя выводами никак работать не может, только 6 выводов. 3 на верхнее плечо и 3 на нижнее плечо. PWM1,2,3 BOT - нижнее плечо фаз, ты его не подключил на изображении. PWM1,2,3 TOP - это верхнее плечо - оно у тебя схематически подключено. No - It can’t work with three conclusions, only 6 conc...

But the price for it is painfully not reasonable for Belarus. Цена продиктована внутренностями мотора. Это медный литой ротор и железо статора из Германии. Покупалось за 500 евро здесь: https://www.kienle-spiess.de/copper-rotors.html . Сейчас цена на этот комплект значительно выше. А цена на контро...

I'd configure it like a normal 6-pole motor (polepairs=3). If run at nominal voltage (how much?) fweak would be around 1500/60*3=75Hz. EDIT: if I understand right the slavynka motor offers no advantage over a normal wound motor when run with an inverter. Переведу: комбинированная обмотка типа "...

Я то-же предполагаю что частотник нивелирует преимущества славянки. У меня 4AMX100L6 перемотанный на славянку 96в 200Гц - поживём - увидим!

I used the minicom utility only for observing the comport to eliminate its malfunction. But the fact is that without it in the browser, the data of the microcontroller does not display.

Hello! I don’t know if I am writing, but I have a similar problem. I have a 2nd version board, the bootloader and the main program are flashed. The green LED blinks pleasantly, the board communicates via Wi-Fi - but the truth is that the ping comes as if from Mars))) but nonetheless, the controller ...

Hi Yahha777 Best of luck with your project with the low voltage motor. Can I ask you, if you rewound the motor yourself or was it done at factory level originally.? I have a similar project that I am working on. Regards Stephen Hello Stephen! I myself was rewinding the electric motor - but the wind...

Yahha777

Hello - my name is Yasha, I am from Belarus. I am also fond of creating an electric car. My project is based on an asynchronous industrial electric motor with rewound windings at 96V 200 Hz. Initially, the project was calculated on the controller Curtis. But - I'm not looking for easy ways! I have c...
