我目前正在与2块板(ESP32和NUCLEO64)之间的中断在UART通信。我有以下代码:
#define rxBufferSIZE (256)
void app_main()
{
UART_init();
uart_isr_free(UART_NUM_2);
uart_isr_register(UART_NUM_2, uart_intr_handle, NULL, ESP_INTR_FLAG_IRAM, &handle_console);
uart_enable_rx_intr(UART_NUM_2);
while (1)
{
}
}
static void IRAM_ATTR uart_intr_handle(void *arg)
{
uint16_t rx_fifo_len;
uint16_t i=0;
rx_fifo_len = UART2.status.rxfifo_cnt; // read number of bytes in UART buffer
while(rx_fifo_len)
{
UART_SlaveRxBuffer[i] = UART2.fifo.rw_byte; // read all bytes
i++;
rx_fifo_len--;
}
/* Some additional code */
uart_clear_intr_status(UART_NUM_2, UART_RXFIFO_FULL_INT_CLR|UART_RXFIFO_TOUT_INT_CLR);
}
static void UART_init()
{
/* Configure parameters of an UART driver,
* communication pins and install the driver */
uart_config_t uart_config = {
.baud_rate = 115200,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = UART_HW_FLOWCTRL_DISABLE
};
uart_param_config(UART_NUM_2, &uart_config);
uart_set_pin(UART_NUM_2, UART_TX, UART_RX, UART_RTS, UART_CTS);
uart_driver_install(UART_NUM_2, rxBufferSIZE * 2, 0, 0, NULL, 0);
}
这两个板之间的沟通工作每次。问题是我多次收到以下错误首次通讯后:
我不知道是什么原因造成这种所以任何帮助表示赞赏。先感谢您!
我冒昧地说while循环在比IDLE0更高的优先级运行,因此IDLE0没有得到重置WDT的机会。
你可以这样做,而不是(如果只是为了测试我的想法):
while (1)
{
vTaskDelay(1); // or 2 or 2; units are 10ms unless you changed it.
}
