While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

Tkinter is a standard GUI library for Python, and it is the most popular Python GUI framework. It is fast, easy-to-use, and provides a wide range of widgets, including buttons, labels, and text boxes.

Unfortunately, Micropython has historically lacked a decent high-level GUI library. Thankfully, that’s no longer the case, with [amirgon] porting LittlevGL to the platform.

Have a nice Python API for interacting with CY7C652xx bridge chips in UART, I2C, and SPI mode Switch a CY7C652xx in between UART, I2C, and SPI mode at runtime (the official driver does NOT support ...
