Hi!
I am trying to create a circuit with the TDK Module.
According to the datasheet the module has the same Pins as the DA14580 Chip.
Can I use the same pins for the ADC measurement? And how can the pins be changed
from for example digital I/O to ADC input?
I found the following image in the datasheet. Is it possible to use this circuit and just have the wanted P0
pins for the ADC measurement connected differently? And what do I have to watch out for when designing
the circuit?
Kind Regards,
Reichel Robert

Hi Robert Reichel,
I am not aware about the inner workings of the TDK module, the pins of the module are identical with the pins of the 580 then the following port/pins implement ADC functionallity P00/P01/P02/P03 (please have a look at the 580 datasheet). In order to use those pins as ADC pins you will have to configure them in the periph_init() function using the GPIO_ConfigurePin() and in the GPIO_FUNCTION parameter use the PID_ADC enumeration. I dont quite get the second question, the circuit that you have attached seems like the minimum componets in order for the module to operate, i dont get what you mean by "have the wanted P0 pins for the ADC measurement connected differently" as mentioned the ADC pins are specific and i dont see them connected anywhere. You also will be able to find a bring up guide for the 580 in the Tutorials section "Tutorial 7:DA1458x prototype bring up guide".
