CC2640R2F: Cannot get which pin is PWM, which pin is ADC for CC2640R2F

Hi Mickey,

The CC2640R2F device allows a lot of flexibility when it comes to peripherals mapping.

- ADC must be mapped on an analog capable pin (i.e. DIO23 to DIO30)

- PWM/UART/I2C/I2S need digital IOs (i.e. any DIO of the device) - so you can map them to any DIO.

More details can be found in the device's datasheet: https://www.ti.com/lit/ds/symlink/cc2640r2f.pdf

I hope this will help,

Hi,

I2S stands for "inter-IC sound". It is used for audio transmission between different devices (typically a codec and the CC2640R2F).

The I2S peripheral can also be re-purposed into a PDM peripheral i.e. a peripheral allowing digital microphone sampling.

You can refer to §22 of the technical reference manual (https://www.ti.com/lit/pdf/swcu117) for more details about the I2S module of the CC2640R2F.

I hope this will help,
