我使用这个工程进行串口接收测试，hosal_uart_dev_t uart_dev_int = {
.config = {
.uart_id = 0,
.tx_pin = 16, // TXD GPIO
.rx_pin = 7, // RXD GPIO
.cts_pin = 255,
.rts_pin = 255,
.baud_rate = 115200,
.data_width = HOSAL_DATA_WIDTH_8BIT,
.parity = HOSAL_NO_PARITY,
.stop_bits = HOSAL_STOP_BITS_1,
.mode = HOSAL_UART_MODE_POLL,
},
};

缺了很多，这是为什么，三种方式都不能完整接收到我发的一帧数据
static void uart_init(void)
{
hosal_uart_init(&uart_dev_int);
hosal_uart_ioctl(&uart_dev_int, HOSAL_UART_MODE_SET, (void *)HOSAL_UART_MODE_INT);
hosal_uart_callback_set(&uart_dev_int, HOSAL_UART_RX_CALLBACK,
__uart_rx_callback, &uart_dev_int);
hosal_uart_callback_set(&uart_dev_int, HOSAL_UART_TX_CALLBACK,
__uart_tx_callback, &uart_dev_int);
hosal_uart_ioctl(&uart_dev_int, HOSAL_UART_TX_TRIGGER_ON, NULL);
// hosal_uart_ioctl(&uart_dev_int, HOSAL_UART_RX_TRIGGER_ON, NULL);
}
static int __uart_rx_callback(void *p_arg)
{
int ret;
hosal_uart_dev_t *p_dev = (hosal_uart_dev_t *)p_arg;
ret = hosal_uart_receive(&uart_dev_int, data_buf, sizeof(data_buf));
printf("__uart_rx_callback : %d\r\n", ret);
for (int i = 0; i < ret; i++)
{
printf("rx num : %d 0x%02x\r\n", i, data_buf);
}
return 0;
}
