MAPLE BOOTLOADER(S)

Step 2: Connect Maple Serial1 to your computer.There are a variety of ways of doing this. We use Sparkfun’s FTDI breakout boards, but you could use another Maple, an Arduino, etc. – anything that allows your computer to communicate with the Maple you want to reprogram over a serial interface.. If you do use an FTDI breakout board, first make sure your Maple is disconnected from an external

ATTACHINTERRUPT()

Most Arduino boards have two external interrupts: numbers 0 (on digital pin 2) and 1 (on digital pin 3). The Arduino Mega has an additional four: numbers 2 (pin 21), 3 (pin 20), 4 (pin 19), and 5 (pin 18). On the Maple, you don’t have to remember which interrupt number goes with which pin – just tell attachInterrupt () the pin

you want.

INTRODUCTION TO STM32 Introduction to STM32. ¶. Every Maple board is powered by an STM32 microcontroller (the chip which controls all of the pins). Once you’re comfortable using your Maple, you’ll probably start to get curious about what’s going on under the hood. This page is a good

place to begin.
