boards/pba-d-01-kw2x: ADC channel mode

[PeterKietzmann]

According to the periph_conf.h there is a single channel mode on the phytec board, which prevents to use ADC_0_CH0 and ADC_0_CH1 separately, when set. Running the periph_adc test shows, that a signal at ADC_0_CH0_PIN affects both ADC_0_CH0 and ADC_0_CH1. A signal at ADC_0_CH1_PIN does nothing. So I assume we actually are in single mode. How can I change that mode? (I mean as a user, not as a developer)

@jfischer-phytec-iot ping?

[OlegHahm]

Who else has the hardware to test it?

[PeterKietzmann]

At least the config file has changed and the above mentioned hint disappeared from that file. I can check this again tomorrow.

[PeterKietzmann]

This is still an open question. ADC_0_CH0 andADC_1_CH1 now refer to

    { ADC0, GPIO_PIN(PORT_E, 2), 1 },
    { ADC0, GPIO_PIN(PORT_E, 3), 1 },

I would vote to either remove the ADC channel on PTE3 (who ever used 6 ADC channels simultaneously?) or provide a switch plus explanation about this mode.

@PeterKietzmann is there still an issue here (since kinetis was refactored a lot recently) ? Maybe @gebart could help ?

[jnohlgard]

It's still an issue, but we need to examine the pba-d-01-kw2x schematics to see what the best configuration could be here.

Once we tried to get them (@cgundogan remember?) to add the button driver. We didn't receive any answer so we did it by looking directly at the board's lines and making tests with the ohmeter... A bit hard but not impossible.

[PeterKietzmann]

In the end - I think - we just need a decision or preference how we do handle it. IMO it is also fine to go with 4-5 pre-configured ADCs. Anyway, for the question of configuration maybe this reference is sufficient?
