在 STM32 上通过 UART 传输

Question

您好，我正在使用 STM32 作为 SI4362 无线电的主机单片机。 无线电使用 SPI 通信进行初始化。 虽然我正在逐步理解我认为从收音机接收正确 CTS 的意思，但它不起作用。 我想将我从 SPI 发送和接收的所有内容传输到 UART 终端进行调试。 这是代码的第一部分。 我从 maker.io 借来的 UART 语法：

   uint8_t RF_POWER_UP[7] = { 0x02, 0x01, 0x01, 0x01, 0xC9, 0xC3, 0x80 };

以上是通过 SPI 发送的变量，因此您可以看到如何尝试发送单个数组。

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_SPI1_Init();
  MX_USART1_UART_Init();
  /* USER CODE BEGIN 2 */

    // CS pin should default high
    HAL_GPIO_WritePin(SS_GPIO_Port, SS_Pin, GPIO_PIN_SET);
    //SHUTDOWN RADIO TO LATERT CONTROL THE POR TIMER
    HAL_GPIO_WritePin(SDN_GPIO_Port, SDN_Pin, GPIO_PIN_SET);

    uart_buf_len = sprintf(uart_buf, "\r\nSPI Test\r\n");
    HAL_UART_Transmit(&huart1, (uint8_t*) uart_buf, uart_buf_len, 100);
    HAL_UART_Transmit(&huart1, RF_POWER_UP, RF_POWER_UP_SIZE, 50);


HAL_GPIO_WritePin(SDN_GPIO_Port, SDN_Pin, GPIO_PIN_RESET);
HAL_GPIO_WritePin(SS_GPIO_Port, SS_Pin, GPIO_PIN_RESET);

int count = 0;

while (!HAL_GPIO_ReadPin(GPIOB, RX_DATA_Pin) && count != 13) {
    HAL_Delay(1);
    count++;
}

count = 0;

for (int i = 0; i < 265; i++) {
    HAL_GPIO_WritePin(SS_GPIO_Port, SS_Pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(&hspi1, theArrays[i], 8, 50);
    //HAL_UART_Transmit(&huart1, theArrays[i], 8, 50);
    do {
        HAL_SPI_Receive(&hspi1, (uint8_t*) spi_buf, 1, 100);
        //HAL_UART_Transmit(&huart1, (uint8_t*) spi_buf, 1, 100);
    } while (*spi_buf != 0xFF);
    HAL_GPIO_WritePin(SS_GPIO_Port, SS_Pin, GPIO_PIN_SET);
}

这是 output 到终端：
