DIY Customizable Touch Deck TFT Control Pad
If you want to buy a touchpad to control all your streaming devices, now you may be interested in a DIY version constructed using an Adafruit Feather RP2040 and 3.5″ TFT display, and this device is powered by CircuitPython. CircuitPython is a derivative of MicroPython designed to simplify experimentation and education on low-cost microcontrollers. It makes it simpler than ever to get prototyping by needing no upfront desktop software downloads. Simply copy and edit files on the CIRCUITPY drive to iterate.
The project uses a 3D printed case which is available to download from the Adafruit online tutorial written by John Park and Foamyguy or from the Thingyverse. The Adafruit Feather RP2040 is outfitted with the newest Raspberry Pi RP2040 chip and gives a 32-bit Cortex M0+ dual-core running at ~125 MHz @ 3.3V logic and power with 264 KB RAM.
“The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit, or DSP hardware support – so if you’re doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you’ll get close-to-M4 speeds!”
