设置ADC转换触发次数的上限是为了限制预处理长度的值; 其他的为字面意思; static void continuous_adc_init(uint16_t adc1_chan_mask, uint16_t adc2_chan_mask, adc_channel_t *channel, uint8_t channel_num) { adc_digi_init_config_t adc_dma_config = { .max_store_buf_size = 256, //驱动程序...

Re: esp32s3 ADC sampling rate Posted:Thu Dec 14, 2023 3:40 pm bydavidribeiro Hello, I have the same question that you had, did you figure out if it was maximum frequency per channel, or if it was the total maximum frequency (as in, each channel will only get a part of that samp...
Re: 【ESP32-S3】 RISC-V ULP协处理器读取多ADC通道 PostbyESP_Gargamel»Mon Jul 25, 2022 2:24 am ulp_riscv_adc_init 是主 CPU 设置 ULP ADC,ulp_riscv_adc_read_channel 是 ULP 中读取。 可以仿造 ulp_riscv_adc_init 写一个支持设置多 channel 的 adc_init。
