I am hoping someone could help me with this UART issue. I am completely new to this embedded programming. Just exploring the world of arm.
I have a problem, I don't see anything output to the Tera Term Terminal. My board is Nucleo STM32L476RG. I hope someone can point me in the right direction
#include "stm32L4xx.h" char msg[] = "Hello World"; int main(void){ uint32_t Baudrate = 115200; // USART1 / GPIOA clock Enable RCC -> APB2ENR |= RCC_APB2ENR_USART1EN; RCC -> AHB2ENR |= RCC_AHB2ENR_GPIOAEN; GPIOA -> MODER |= GPIO_MODER_MODER9_1; GPIOA -> OTYPER &= ~(GPIO_OTYPER_OT9); GPIOA -> OSPEEDR |= GPIO_OSPEEDER_OSPEEDR9; USART1 -> BRR = SystemCoreClock / Baudrate; // for 80Mhz on APB2 USART1 -> CR1 |= USART_CR1_TE | USART_CR1_UE; while(1){ USART1 -> TDR = msg[1]; // TDR = Transmist Data Register } }
