KDS V3.0.0
KSDK V1.3.0
I am able to get the Debug Console UART routines to work just fine. However, when using the UART Peripheral Drivers (UART_DRV_*) to work, I am unable to get these routines to work properly. In the example below, I am getting only the first letter of the string buffStart to display in an infinite loop on the receiving RS232 port. As you can see below, I have tried this blocking and non-blocking, to no avail. I am using the GPIO LEDs as debugging features so please ignore these. Any ideas what is happening here with the UART?
int main(void)
/*lint -restore Enable MISRA rule (6.3) checking. */
{
/* Write your local variable definition here */
uint8_t buffStart[] = "++++++++++++++++ UART Send/Receive Non Blocking Example +++++++++++++++++\r\n";
uint8_t bufferData1[] = "\r\nType characters from keyboard, the board will receive and then echo them to terminal screen\r\n";
uint8_t byteCountBuff, txChar, rxChar;
/*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
PE_low_level_init();
/*** End of Processor Expert internal initialization. ***/
/* Write your code here */
GPIO_DRV_Init(gpio1_InpConfig0, gpio1_OutConfig0); // Initialize GPIO
GPIO_DRV_WritePinOutput(LED_RED, ON); // Set LED to RED while program loads
UART_DRV_Init(UART0_IDX, &uartCom0_State, &uartCom0_InitConfig0);
// Inform to start non blocking example
byteCountBuff = sizeof(buffStart);
UART_DRV_SendDataBlocking(UART0_IDX, buffStart, byteCountBuff, 1);
//UART_DRV_SendData(UART0_IDX, "Hello", 5);
GPIO_DRV_WritePinOutput(LED_RED, OFF);
GPIO_DRV_WritePinOutput(LED_GREEN, ON);
// Wait until transmission is finished
//while (kStatus_UART_TxBusy == UART_DRV_GetTransmitStatus(UART0_IDX, NULL)){}
GPIO_DRV_WritePinOutput(LED_GREEN, OFF);
GPIO_DRV_WritePinOutput(LED_BLUE, ON);
// Inform user of what to do
byteCountBuff = sizeof(bufferData1);
UART_DRV_SendDataBlocking(UART0_IDX, bufferData1, byteCountBuff, 1);
GPIO_DRV_WritePinOutput(LED_RED, ON);
// Wait until transmission is finished
//while (kStatus_UART_TxBusy == UART_DRV_GetTransmitStatus(UART0_IDX, NULL)){}
GPIO_DRV_WritePinOutput(LED_GREEN, ON);
for(;;)
{
// Call received API
UART_DRV_ReceiveDataBlocking(UART0_IDX, &rxChar, 1u, 1);
// Wait until we receive a character
//while (kStatus_UART_RxBusy == UART_DRV_GetReceiveStatus(UART0_IDX, NULL)){}
// Echo received character
txChar = rxChar;
UART_DRV_SendDataBlocking(UART0_IDX, &txChar, 1u, 1);
};
