Hi,
Thanks for Reply.
I am just little bit confuse here regarding tout interrupt. would you please let me know tout interrupt is same as UART Receive Byte Interrupt or it is different?
Below is out UART configuration code.
Code: Select all
uart_config_t uart_config = {
.baud_rate = baud_rate,
.data_bits = UART_DATA_8_BITS,
.parity = UART_PARITY_DISABLE,
.stop_bits = UART_STOP_BITS_1,
.flow_ctrl = hw_flow,
.rx_flow_ctrl_thresh = 122,
};
vTaskDelay(10 / portTICK_RATE_MS);
uart_status = uart_param_config(uart_num, &uart_config);
if(uart_status == ESP_OK)
{
DEBUG_LOGI(UART,TAG1,"UART %d configured successfully...",uart_num);
if(hw_flow==GW_UART_HW_FLOWCTRL_DISABLE)
{
uart_status=uart_set_pin(uart_num,tx ,rx,UART_PIN_NO_CHANGE,UART_PIN_NO_CHANGE );
}
else if(hw_flow==GW_UART_HW_FLOWCTRL_RTS)
{
uart_status=uart_set_pin(uart_num,tx ,rx,rts,UART_PIN_NO_CHANGE );
}
else if(hw_flow==GW_UART_HW_FLOWCTRL_CTS)

uart_status=uart_set_pin(uart_num,tx ,rx,UART_PIN_NO_CHANGE,cts);
}
else

uart_status=uart_set_pin(uart_num,tx ,rx,rts,cts);
}
}
else
{
DEBUG_LOGI(UART,TAG1, "ERROR : UART%d failed to configure...",uart_num);
return false;
}
if(uart_status==ESP_OK)
{
uart_status=uart_driver_install(uart_num, 1024 * 2, 1024*4, 128, &uart_queue[uart_num], 0);
uart_flush(uart_num);
}
else
{
DEBUG_LOGE(UART,TAG1,"UART%d set pin error",uart_num);
return false;
}
Code: Select all
xTaskCreate(uart0_task, "uart_0", UART_TASK_SIZE, (void*)uart_num, UART_TASK_PRIO, &uart_handler[GW_UART0]);
Code: Select all
void uart0_task(void *arg)

Let me know if we had did anything wrong which is creating Task Watchdog Trigger Issue while reading data with dynamic interval and size from UART Module attached with ESP32.
