After checking for shorts on the PCB and finding none, I applied power. I suspected it would not work without the USB Power controller and I was correct. But grounding the control for the P_FET brought 5 VDC to the power section and all the DC-DC converters powered up.
Then I built the Board Support Package for the Microchip MPLAB X Harmony system. Finally did a very simple program to blink the BLUE/YELLOW USB connection LEDs that I use in all of the MyMakerTools products. The result is below.
Next is to build the I2C driver and the application code for the LP5569 LED controller. I have this mostly done from a previous prototype, but need to convert it to the Harmony structure.
