Functions

dma_init

Init DMA for the ADC Channel. See bl_adc_dma_init in “init_adc” https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c

freq_init

Init the ADC Channel Frequency. See bl_adc_freq_init in “init_adc” https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c

get_channel_by_gpio

Get the ADC Channel Number for the GPIO Pin. See bl_adc_get_channel_by_gpio in “init_adc” https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c

gpio_init

Configure the GPIO Pin as ADC Input (no pullup, no pulldown). See bl_adc_gpio_init in “init_adc” https://github.com/lupyuen/bl_iot_sdk/blob/adc/customer_app/sdk_app_adc2/sdk_app_adc2/demo.c

init
