The CH559 is a 8051 architecture based microcontroller that has built in dual USB Hosts. This allows to interface generic Keyboards, Mice, MIDI devices and in my case gamepads. I added this chip as an add on to my ESP32 based game console to replace the SNES controllers by cheap generic ones. The communications is handled over UART which can be done by both ends in hardware. There still is some work to do but you can try it out already. Have fun!

Drop on mass storage that's showing up when connecting the Pico W to your computer 3. You can use thonny.org IDE to use the shell and execute individual commands. Or create new files and store them on the Pico W like the contents from this example github.com/pi3g/pico-w 4. Set your wifi credentials in secrets.py 5. Execute the code and open the IP that's displayed in the console when the Pico is connected.
#electronics #raspberrypi #shortsCheap grid tie solar setup (600W 3kWh/day)bitluni2022-06-17 | I needed an upgrade for my solar setup since the utility bills got outrageous. The cheap grid tie inverter is easy to setup and saves me 1€/day now. I tested the microinverter and it's working fine making 3kWh/day with two 300W panels. The highest output I measured with my clamp meter at was 2A AC which corresponds to about 520Watts. That's nice because I didn't spend a penny for the mount. The app allows to control the output so you can limit it if you need.
