use ESP32 local PIN for the 8 channel #21

Hi, ESp32 has enough pin for the 8 channels. Can you share me how to do that?

arijav commented 3 years ago

Hi, in my board there are not enough pings for 8 channels due to the interface pins to the Lora E22 module. You can however create a board based on my design, removing the Lora module, the port expander and driving the triacs directly with the ESP32. If you create such a board have a look to the SW from J.Charer (https://github.com/JaCharer/OpenSprinkler-Firmware-ESP32port) as he is driving the outputs with ESP32 pins and no port expander

Yes, i saw his code but it looks like there's no support for MQTT in his code, which is important. Yes, i plan to add NRF24. Are you sure that not enough PIN for 8 channels?

In my board there is no place for sure. Below you can find a link to the table where you can see the use of each ESP32-WROOM pin (column G):

i update the front end app code because it is hardcoded in fhe main.js and the GPIO pin is working but not sure if this is the proper way.
