i had a problem when i send a character or receive a character , i always get a wrong character like ''-'' or a heart ...
ps: i'm using rs232 -> USB converter
here is my code:
&sharpinclude ''stm32f4xx.h''
void main()
{
//UART4 initialization
RCC->APB1ENR |= 0x00080000; // Enable clock for UART4
RCC->AHB1ENR |= 0x00000004; // Enable clock for GPIOC
GPIOC->MODER |= 0x00a00000; // PC10, PC11 => AF mode
GPIOC->AFR[1] |= 0x00008800; // select AF8 (UART4,5,6) for PA10, PA11
UART4->BRR = 0x1120; // 9600 baud
UART4->CR1 |= 0x200c; // Enable UART for TX, RX
UART4->CR1 |= 0x0020; // Enable RX interrupt
while(1){
if (UART4->SR & 0x0080) {
UART4->DR='a';
for (int i=0; i<10000000; i++) {};
}
}
}
please any help! :(
