Using the 8 bit bi-directional port

[wesaymorning]

Hello Folks!

From the Power Profiler Kit II v1.0.1 documentation, the block diagram shows the logic port as bi-directional.



There is no further mention (that I can find) of using this port as an output.

Has anyone been able to achieve this ?

Thanks

This port only supports digital inputs for the logic analyzer today. No current plan to use it as output, output feature is to future proof the design.

Another case regarding the PPK 2 identified the breathing LED as a source of SAADC measurement noise. Hakon kindly arranged to do an update "we will release a new version for existing hardware. I do not have the overall details on how configurable this will be, but it is likely going to be a solid state when sampling (ie. no PWM), and/or possibly an update to the GUI to turn the LED feature on/off completely". This would allow the use of up to 3 output pins to control the device-under-test (DUT) by simply hijacking the LED pins which is a better solution for us than having another device to qualify. (The other io input pins would be preferred, but there are buffers in the way of those.)

Thanks hakon

Edit: Better still, allow us to modify the nRF52840 project on the PPK 2 so we can add some more commands.
