Parallel LCD displays on ESP32-S2 with CircuitPython #ESP32 #CircuitPython @EspressifSystem @Adafruit
CircuitPython 7 supports the parallel display bus on several microcontrollers, including the ESP32-S2 from Espressif. In a pull request from Adafruit, Adafruit makes the ESP32-S2 even faster and more flexible. Here (video) Jeff shows just how fast the work in progress code is at refreshing the text console.
Depending on the display, you may be able to connect to it using I2C, SPI, or the parallel bus. Because the parallel bus transmits
multiple bits at a time, it can be faster than the other two (but it uses a lot more microcontroller pins).
If you have a PyPortal and wonder why the display refreshes more quickly than on some other boards with CircuitPython, this is why.
Stay tuned for more work from Adafruit on CircuitPython 7 and beyond – all open source software and hardware.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
