MEAM.Design - MAEVARM - Custom Header File

The custom m_general.h file provides some useful features specific to the M2 (and older M1) microcontroller board. This is a work in progress, and you are highly encouraged to add/modify/update this file and post changes here (just add a new line with your version and notes about what has been added - as time goes by changes will be rolled into official releases).

OFF (0)
ON (1)
TOGGLE (2)


provides the following macro functions:

set(register,n) - sets the n-th bit of register
clear(register,n) - clears the n-th bit of register
toggle(register,n) - toggles the n-th bit of register
check(register,n) - returns the state of the n-th bit of register
m_disableJTAG() - turn off JTAG port and allow access to F4-F7 as GPIO
m_clockdivide(N) - reduces the system clock speed by 2^N (N=0..8)
m_wait(ms) - delay the microcontroller for an integer number of milliseconds (assumes a 16 MHz system clock)
m_green(state) - set the state of the green on-board LED to OFF, ON, or TOGGLE
m_red(state) - set the state of the red on-board LED to OFF, ON, or TOGGLE
