After esp-idf update, UART doesnt work. The following code, result in:
Code: Select all
uart_config_t uart_config;
uart_config.baud_rate = 115200;
uart_config.data_bits = UART_DATA_8_BITS;
uart_config.parity = UART_PARITY_DISABLE;
uart_config.stop_bits = UART_STOP_BITS_1;
uart_config.flow_ctrl = UART_HW_FLOWCTRL_DISABLE;
uart_config.rx_flow_ctrl_thresh = 120;
uart_param_config(MODULE_UART_NUM, &uart_config);
uart_set_pin(MODULE_UART_NUM, GPIO_NUM_26, GPIO_NUM_25, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE);
uart_driver_install(MODULE_UART_NUM, 2048, 2048, 10, 17, NULL);Code: Select all
