I have GPIO in Atollic with PEx working (bitbanged SPI), using the BitIO component. However, in KDS+PEx, I don't have that component for some reason. My non-PEx bitbang SPI code doesn't work, so I decided to use PEx in KDS.
I tried fsl_gpio, but there seems to be a bug where I cannot assign the port. If I select PORTD, for example, it switches back to PORTA as soon as I click somewhere else. And of course, since I want two (different) ports, I get an additional error saying that the two components are sharing a port.
So I decided to move on to try the GenericBitIO component in KDS+PEx. Setup seemed clear enough until I saw this GUI:
I already set the Direction under the Component Name, so I don't understand why I would have to set something in a Direction tab. In addition, I tried to figure out the significance of PTADD_PTADD0, but I can't find any part of that in the reference manual. Also, the checkbox should really just be labeled "Output" or "Is output".
I was going to keep moving forward and just ignore this detail regarding direction, but I also can't figure out what the valid port names or bit names are that I should be using. When PEx uses a droplist with the header and pin number (e.g. J2_12), it's so much easier to configure. Droplists >> textboxes!
I had BitIO in Atollic+PEx working in 5 minutes. So far, I've spent over four hours trying to get my IO code working in KDS. I'm not sure why this is, but I'm going to keep plugging away at it.
