Example host MCU sketch to demonstrate use of the USFSMAX coprocessor

Keyboard Controller, using Teensy 3.2 and ST7735 display. Editing key mappings, layers and sequences in real time. With also few display demos and a game.

This library enables you to use Interrupt from Hardware Timers on an Teensy-based board such as Teensy 4.x, 3.x, LC, 2.0, etc. These Teensy Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using mill…

SPI like protocol interfacing via6522 (oric atmos) with teensy 3.2

This library enables you to use ISR-based PWM channels on Teensy boards, such as Teensy 2.x, Teensy LC, Teensy 3.x, Teensy 4.x, Teensy MicroMod, etc., to create and output PWM any GPIO pin. It now supports 16 ISR-based PWM channels, while consuming only 1 Hardware Timer. PWM channel interval can be very long (ulong microsecs / millisecs). The mo…
