如何修复 ESP32 rmt: rmt_transmit(476): channel not in enable state
如果在 rmt_transmit() 调用期间收到以下错误：
esp32_rmt_fix.txt
rmt: rmt_transmit(476): channel not in enable state调用
rmt_enable_fix.cpp
ESP_ERROR_CHECK(rmt_enable(channel));在调用 rmt_new_tx_channel() 之后。
完整初始化示例
rmt_full_init_example.cpp
rmt_channel_handle_t channel;
rmt_tx_channel_config_t tx_chan_config = {
.gpio_num = GPIO_NUM_19, // GPIO number
.clk_src = RMT_CLK_SRC_DEFAULT, // select source clock
.resolution_hz = 1 * 1000 * 1000, // 1 MHz resolution
.mem_block_symbols = 64, // memory block size, 64 * 4 = 256 Bytes
.trans_queue_depth = 1, // set the number of transactions that can pend in the background
};
ESP_ERROR_CHECK(rmt_new_tx_channel(&tx_chan_config, &channel));
ESP_ERROR_CHECK(rmt_enable(channel));Check out similar posts by category:
