Hello,
I have problem with transmit data by UART.
When I try transmit one byte, I see in debug mode how changed register TXDAT UART0 (0x4006401C). But recepient not get this data I use FTDI232 usb to ttl
My code:
usart_config_t user_config;
volatile uint32_t g_systickCounter;
void SysTick_Handler(void)
{
if (g_systickCounter != 0U)
{
g_systickCounter--;
}
}
void SysTick_DelayTicks(uint32_t n)
{
g_systickCounter = n;
while(g_systickCounter != 0U)
{
}
}
int main(void) {
// /* Init board hardware. */
BOARD_InitBootPins();
BOARD_InitBootClocks();
BOARD_InitBootPeripherals();
// /* Init FSL debug console. */
BOARD_InitDebugConsole();
if(SysTick_Config(SystemCoreClock / 1000U))
{
while(1)
{
}
}
USART_GetDefaultConfig(&user_config);
user_config.baudRate_Bps = 9600U;
user_config.enableTx = true;
user_config.enableRx = true;
USART_Init(USART0, &user_config, DEFAULT_SYSTEM_CLOCK);
uint8_t ch=65;
while(1) {
USART_WriteByte(USART0, ch);
SysTick_DelayTicks(1000U);
}
return 0 ;
}
Pin init
void BOARD_InitPins(void)
{
/* Enables clock for switch matrix.: 0x01u */
CLOCK_EnableClock(kCLOCK_Swm);
/* USART0_TXD connect to P0_4 */
SWM_SetMovablePinSelect(SWM0, kSWM_USART0_TXD, kSWM_PortPin_P0_4);
/* USART0_RXD connect to P0_0 */
SWM_SetMovablePinSelect(SWM0, kSWM_USART0_RXD, kSWM_PortPin_P0_0);
/* SWCLK connect to P0_3 */
SWM_SetFixedPinSelect(SWM0, kSWM_SWCLK, true);
/* SWDIO connect to P0_2 */
SWM_SetFixedPinSelect(SWM0, kSWM_SWDIO, true);
/* Disable clock for switch matrix. */
CLOCK_DisableClock(kCLOCK_Swm);
}
When I wrong?
