#GPIO, #I2C or SPI code is mostly found in the #MCU area. (Greetings from #arduino )
Linux device interface is great too to make #raspberryPi and friends hw-dev platforms.
But what happened to Windows?
I couldn't find any common driver interface to talk to GPIO pins or I2C/SPI devices.
But there is the #FT232H chip and its high-level #libmpsse library.
So this is now "my way to go" with GPIO stuff on Windows.
First wrapper library draft is ready and my #SSD1306 display works, but its quite slow.
