器件型号：MSPM0C1104 我正在使用 MSPM0C1104、但向 UART 发送十六进制值时遇到困难、请建议我如何将十六进制值发送到超过4字节的 UART、例如 #define OpenLID ｛0x11、0x22、0x33、0x44、0x55、0x66｝；
以下是源代码。
/*
* Configure the internal loopback mode.
* Note that data received on the UART RXD IO pin will be ignored when
* loopback is enabled.
*/
#define ENABLE_LOOPBACK_MODE true
/*
* Number of bytes for UART packet size
* The packet will be transmitted by the UART.
* This example uses FIFOs with polling, and the maximum FIFO size is 4.
* Refer to interrupt examples to handle larger packets.
*/
#define UART_PACKET_SIZE (4)
/* Delay for 5ms to ensure UART TX is idle before starting transmission */
#define UART_TX_DELAY (160000)
#define OpenLid {'M', 'S', 'P', '!'};//{0x11,0x22, 0x33, 0x44};

UART_Write( txPacket, size);
}
void UART_Write(uint8_t *DataBuffer,uint8_t size){

for (int i=0; i<size; i++){
/* Fills TX FIFO with data and transmits the data */
DL_UART_Main_fillTXFIFO(UART_0_INST, &txPacket[i], UART_PACKET_SIZE);
}
/* Wait until all bytes have been transmitted and the TX FIFO is empty */
while (DL_UART_Main_isBusy(UART_0_INST))
;
}
int main(void)
{
SYSCFG_DL_init();
// /*
// * Wait to receive the UART data
// * This loop expects UART_PACKET_SIZE bytes
// */
// for (uint8_t i = 0; i < UART_PACKET_SIZE; i++) {
// rxPacket[i] = DL_UART_receiveDataBlocking(UART_0_INST);
// }
/* If write and read were successful, toggle LED */
while (1) {
uint8_t arr[] = OpenLid;
UART_Write_buffer(arr, 5);
//UART_Write(txPacket,4);
DL_GPIO_togglePins(GPIO_LEDS_PORT,
GPIO_LEDS_USER_LED_1_PIN | GPIO_LEDS_USER_TEST_PIN);
delay_cycles(1200000);
}
}
