SmartSerial on cheap ESP32-8ch-Relais Card

Hi,
i modified the  mesa-smartserial-device-template a little bit
and put it on a cheap ESP32 8ch-Relay board for extra Outputs.

i used platformio as buildsystem for easy use, i have also test the code on raspberry-pico,

Relay-Board: www.amazon.de/dp/B0FNRH8QSN

Optional: www.amazon.de/TECNOIOT-Two-Way-Transfer-...tional/dp/B081J5R35N

Works fine with 7i92, but have still problems with 7c81 SmartSerial connector, not shure why,
maybe my pinout is wrong or problems with the TX_en stuff.


my Board with RS422 mod:
 

ok, works also on the 7c81 ports

Small soldered board, is it the RS422 to RS232 converter, or just a line driver?
Nice work, i do like the ESP32 due to it's versatility.
Thank you.

the small one is an RS422 to TTL

Essas placas ESP32 baratas funcionam, mas exigem mais testes do que soluções industriais. A fase experimental faz lembrar os primeiros passos dos casinos em portugal no ambiente digital. Testar, errar e ajustar faz parte do processo.

Hello, I'm trying to clone this board. Do you have any HAL file references?

no, but you can see the new pins with:

halcmd show

The translation into English is:

"Do I only need this HAL configuration:

loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=1 num_pwmgens=1 num_stepgens=5 sserial_port_0=0xxxxxxx"

Or are there other settings required as well?"

The translation into English is:

"Is the 7I92 pin compiled as:

10 30 IOPort SSerial 0 TXData0 (Out)
11 31 IOPort SSerial 0 RXData0
?
