land-boards.comI've got a Raspberry Pi Hat (board) which is an I/O card for the Raspberry Pi, the RPP-UIO-16. It has 16-bits of I/O translators on it as well as connections to all of the GPIO pins on the 40-pin connector. The hat is the standard form factor as other hats and happens to match the RPI_PSOC5 card.
I hooked up jumpers to take the 3.3V side of the translators to 16 of the GPIO lines from the Raspberry Pi connector. I hooked up 16 LEDs to these 5V signal level lines. I also hooked up LEDs to the other pins and ran code to bounce light across each of the LEDs. This showed that the RPP_PSOC5 can set all of the lines properly.
The code has been written to use the BCM pin names. On the GPIO connector, these are:
