Hello friends, I hope you all are doing great. Today, I am going to share the Teensy 4.1 Library for Proteus . The Teensy 4.1 from PJRC is one of the fastest boards you can program in the Arduino IDE: an NXP i.MX RT1062 - an ARM Cortex-M7 at 600 MHz with 1 MB of RAM and 8 MB of flash - on a stick of a board 61 mm long. With this library it runs your Teensy Arduino sketch in Proteus 8.5, with the Teensy's own pin numbers.
