Re: Yunshan z ESP-07

Cóż, mi tak zadziałało. Więc nie "na pewno nie"

Re: Yunshan z ESP-07

W ESP-07 miałem taką sytuacje że trzeba połączyć TX z TX i RX z RX. Spróbuj, może masz to samo.

Re: woltomierz 6 wejść na arduino mega

Wow, great: D As soon as I reach wemos and the multiplexer to report on the action !!
Many thanks Elmaya !!!!

Re: woltomierz 6 wejść na arduino mega

I change concepts. Could I ask you @elmaya for the scheme and soft to wemos d1 for voltmeter up to 30V? I will have a preview of the entire packet charge and the voltage value on individual cells will be visually visible through 10 segment LEDs.

Re: woltomierz 6 wejść na arduino mega

Unfortunately, I am not so familiar with this. I'm just looking for the voltage preview option, the rest will be done by visualization through 10 segment LEDs.

Re: woltomierz 6 wejść na arduino mega

I found something interesting:

I just want to view online tension, BMS will be in addition, but maybe this project above will be interesting to develop?

Re: woltomierz 6 wejść na arduino mega

I'm going to build a powerwall from 18650 cells in size 7S. All for charging with the Volt SINUSPRO-2000S solar inverter. its maximum charging voltage is up to 29V, so don't worry, the maximum voltage on the cell is around 4.14V. The whole is connected in parallel in a 10-size powerwall and ultimate...

Re: woltomierz 6 wejść na arduino mega

@elmaya , great thing, but I'm not sure it will work in a serial connection. I want to measure the voltage on such a board through a dedicated P1 connector : https://easyeda.com/editor#id=fdceba4bdb9a4466b445f5718b28528f|f076d8c2d4794896a12e053e62bd4a04, Ground is not common and if I connect it acco...

Re: woltomierz 6 wejść na arduino mega

Szukam podobnej opcji tylko potrzebuje mierzyć 7 napięć do 5V. Najlepiej gdyby taką opcję dało się zrealizować np przez Wemosa i jakiś multiplexer. Niestety nie znam się na kodach arduino i w zasadzie nie musiałoby to być rejestrowane w Supli , byleby dało się wysyłać te dane na jakiś ogólnodostępn...
