Hello, I am currently developing a USB PD power bank that utilizes bi-directional 60W input and 100W output. My plan is to use SC8815 I2C bidirectional buck-boost controller for Power and CYPD 3171 as the PD controller. I want to use CYPD3171 to control SC8815 over I2C to configure SC8815 modes(input and output) as well as output and charging voltage, etc. I also want CYPD3175 to inform the main MCU of PD modes, voltages, currents etc. My question is that what is the best way to achieve this functionality? Should I use EZ-PD config utility or PSOC programmer to write the code? Also, how should I upload the program onto CYPD3175, can I use an ST-Link, or use another MCU over I2C? Can someone recommend me a software and programmer combo? I saw this reference design using sc8915 which is extremely similar to my application, and I think I am going to reference the schematic, but I don't see where the code is located, could someone also inform me of where it is located so I can use it as a reference if possible? I am new to the CCG3 ecosystem, thank you very much!
