Hi,
I started a project from scratch and I want to write a simple UART printf solution for debugging for my NRF52832 on PCA10040 DK. I know there's a LOG module but it seems too complicated for my use case.
I'm using sdk_config.h from examples/peripherals/uart, and I'm using a custom build system (it's googlable) using cmake. The system basically includes a module and all of its dependencies.
I tried uart example and everything works as it should so the pin numbers are correct and serial settings on PUTTY are correct. I tried lots of stuff but nothing seems to work. I'm flashing the code alongside SoftDevice, could that make a difference??? Any help is greatly appreciated. Thanks!

#include "bsp.h"

const app_uart_comm_params_t uart_conf = {
.rx_pin_no = 30,
.tx_pin_no = 31,
.rts_pin_no = RTS_PIN_NUMBER,
.cts_pin_no = CTS_PIN_NUMBER,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED,
.use_parity = false,
.baud_rate = NRF_UART_BAUDRATE_115200
};
int main(void)
{
uint32_t err_code;
bsp_board_init(BSP_INIT_LEDS);
APP_UART_INIT(&uart_conf,
NULL, APP_IRQ_PRIORITY_LOWEST, err_code);
if (err_code == NRF_SUCCESS)
bsp_board_leds_on();
else
bsp_board_leds_off();
printf("\r\nHello\r\n");
for(;;)
{
uint8_t ch = 0;
while (app_uart_get(&ch) != NRF_SUCCESS);
while (app_uart_put(ch) != NRF_SUCCESS);
if (ch == 't')
{
bsp_board_leds_off();
while(1)
{
;
}
}
}
return 0;
}
