But I need my software to run on an ARM device. This software runs on 32 and 64 bit windows, linux and mac, which is already an impressive list.

There is stock software with this inverter and many other inverters and UPS’s that use the same chip.

This is the lsusb output: $lsusb -vd 0665:5161īus 001 Device 004: ID 0665:5161 Cypress Semiconductor USB to SerialĬouldn 't open device, some information will be missingīDeviceClass 0 (Defined at Interface level) The inverter uses a Cypress Serial to USB chip for communication with device ID 0665:5161. This post just shares the quest I went through. In the end this was easier than I thought it would be and it was a whole lot of fun. Unfortunately this wasn’t true, requiring me to reverse-engineer the USB communication for it. I was expecting it to be a serial over USB port that would just work as-is with a usb to serial driver, especially because it advertises itself as a Cypress USB to Serial device when you attach it to your computer. The first client I wanted to deploy it with has a similar inverter from the same company, just with a usb port instead of RS232. I have a minimal viable product working based on an RS232 enabled inverter I have here. The last few weeks I have been busy on a solar monitoring project.
