ADC1_CHANNEL_7 24.2.3原理图 ADC属于ESP32-S3内部资源，实际上我们只需要软件设置就可以正常工作，...
ADC_Init(ADC1, &ADC_InitStructure); // PA2对应的channel是 ADC_Channel_2 ADC_RegularChannelConfig(ADC1, ADC_Channel_2, 1, ADC_SampleTime_239Cycles5); // 启用ADC1的外部触发源 ADC_ExternalTrigConvCmd(ADC1, ENABLE); // 在 ADC1 上启用 DMA ADC_DMACmd(ADC1, ENABLE); ADC_Cmd(ADC1, ENA...
在读取ADC数据之前,必须先对ADC进行设置,然后才可以读出数据,设置的示例代码如下: //Configure ADC if (unit == ADC_UNIT_1) { adc1_config_width(ADC_WIDTH_BIT_12); adc1_config_channel_atten(channel, atten); } else { adc2_config_channel_atten((adc2_channel_t)channel, atten); } 1. 2. 3...

adc_dma_config.adc1_chan_mask |= BIT(channel2); adc_pattern[0] = { .atten = ADC_ATTEN_DB_11, .channel = channel1, .unit = ADC_UNIT_1, .bit_width = ADC_WIDTH_12Bit }; adc_pattern[1] = { .atten = ADC_ATTEN_DB_11, .channel = channel2, .unit = ADC_UNIT_1, .bit_wid...

Common wisdom on the Internet is to avoid attempting to use channel 2 ADC together with Wi-fi -- I couldn't even find any success reports. The battery examples in this repo are, suspiciously, running with wifi off, and the wifi example doesn't monitor the battery. Before I spend too ...
