Hello all I am using nRF52382 I am using SEGGER Embedded studio for programing. I want to use pins 12 and 11 as Rx and Tx for UART. I changed the default pins to #define RX_PIN_NUMBER 12#define TX_PIN_NUMBER 11 in pca10040.h but it is not working.

Hello all I am using nRF52832 I am using SEGGER Embedded studio for programing. I want to use pins 12 and 11 as Rx and Tx for UART. I changed the default pins to
#define RX_PIN_NUMBER 12#define TX_PIN_NUMBER 11 in pca10040.h but it is not working. Could someone guide me through with the said issue.

Are you using the UART for RTT debug information? If yes,...please make sure the RX handler conflict issue. However,....You may check by the steps

1) sdk_config.h RX,TX pin definition is not declared by the other pins.

2) GPIO configuration. pin11, pin12 are never assigned by the other GPIOs.

3)To  connect the pin11 for logic analyzer or digital scope to check TXD signal.

4) Make sure the baud rate clock source is exact.

Hi Henry_Chou

 

pin 11 is used #define SER_CONN_CHIP_RESET_PIN     11    // Pin used to reset connectivity chip

I have commented it out 

#define SPIM2_SCK_PIN   12  // SPI clock GPIO pin number.

I have commented it out 

 GPIO configuration. pin11, pin12 are not assigned by the other GPIOs.

Hi PaSi

Im facing the exact same problem and im using the same TX and RX pins that youre using. Did you find a fix for the problem ? If so please help me out 

Thank you in advance
