Configuration UARTE with nrf52805 for ESB - Part 2

[Ilary]

My previous ticket is closed. I would need, but still help with the configuration of the pins. I report my last post.

Hello,
I did some tests with the oscilloscope directly connected to pins 21 and 18 of the nrf52805.
The transmission on pin 18 by the Stm8l works perfectly. The problem I encounter now is that nrf52805 I have the pull up instruction on this pin

 nrf_gpio_cfg_input(PIN_RXD,GPIO_PIN_CNF_PULL_Pullup);

but nothing happens when oscilloscopes.

It could be that I get the pin definition wrong initially

 #define UARTE_BASE           0x40002000
  #define PORTA_UARTE          ((NRF_UARTE_Type *) UARTE_BASE )
  #define PIN_TXD            21
  #define PIN_RXD            18

or the pull up configuration of pin 18, set as input and pin 21 as output?

 nrf_gpio_cfg_input(PIN_RXD,GPIO_PIN_CNF_PULL_Pullup);
     nrf_gpio_cfg_output(PIN_TXD);

1 I disabled flow_control

2 I brought to 1 the define in sdk_config.h

3 I removed the define NRF52 from the preprocessor

 what are the files to be replaced?

always remove develop_in_nrf52832 as a preprocessor definition?

I still tried to compile after doing the first 3 steps listed but I have an error and it crashes the compilation for completeness the project works in this way : stm8 sends on uart to nrf52 in turn nrf52 sends to another nrf52 (remote device) the same data received. I can not currently answer the questions you asked me because I can not know if after the changes you proposed the situation changes
