Thank you for your response , I have changes the bit as per your suggestion but i still see no communication, I have changed the data as GPIOA->CRL |= GPIO_CRL_MODE2_Msk; /*Eanble Max frequency of 50 MHz(11)*/ GPIOA->CRL^= (GPIO_CRL_CNF2);/*E...

I have changed the code as per your comment but I am not able to transmit the data. I have also altered the CRL and now it reads 'B' - 1011 for the pin A2 and A3. Can you please tell me any changes to be done?

@Charlie4918 : Can you please tell me why the equation return ((PeriphClk +(BaudRate/2U))/BaudRate); was used?

Thank u all for the response. I have edited my code like this and this worked:#include "stm32f103x6.h"int main(void){ RCC->APB2ENR |= RCC_APB2ENR_IOPCEN; GPIOC->CRH |= 0x44344444; while(1) { GPIOC->BSRR = GPIO_BSRR_BS13; for(int i = 0...

I am trying to communicate between Bluepill and Arduino but I am not able to see the data transfer happening. The code details are as below:

Dear Community members, I am writing code from scratch to glow LED present in PC13 of STM32F103C(Blue pill) but the LED is not getting turned ON. Kindly help me with this. I am attaching the code below.
