RE: KC868-A64 configure for ESPhome - nurachese - 03-18-2023

Hi all,
I am having an issue with this board.
I configured ESPHome as per your instruction but one PCF8575TS (address 0x25) corresponding to outputs 17-32 is not working properly.
All other PCF8575TS are perfectly working.
I checked voltage on pin A0, A1 and A2 of PCF8575TS (according data sheet these pins are defining the address) and everything is correct (A0 3.3V, A1 GND, A2 3.3V).
ESPHome log says:

It seems a failure of PCF8575TS chip.

Can you please confirm?

Thank you


RE: KC868-A64 configure for ESPhome - admin - 03-18-2023

check your esphome LOG, it will scan all I2C bus device address and output in LOG. whether one of PCF8575 address is wrong.

Hi,
I posted the  esphome LOG.
address 0x25 is correct since I verified it with voltage levels on pins A0, A1, A2 of  PCF8575.
It seems a failure of PCF8575 (infact after boot all I/Os of that specific IC are high, as described on  PCF8575 datasheet... it seems there is no communication).

Thank you

Marcello


RE: KC868-A64 configure for ESPhome - admin - 04-01-2023

at begin of ESPHome LOG , after work begin with IIC, that will showed all scaned IIC address. check here, whether address is not 0x25.


RE: KC868-A64 configure for ESPhome - Milos - 11-16-2023

Hello,
Which type of connector is use for extend i2c and serial?
Can you give aliexpress url please?


RE: KC868-A64 configure for ESPhome - admin - 11-16-2023

just use 2.54mm connector.
   


RE: KC868-A64 configure for ESPhome - Oium - 12-22-2023

What pins are used for modbas?


RE: KC868-A64 configure for ESPhome - admin - 12-22-2023

RS485 use modbus.
