|
|
; The software was initially designed for use with Eflite mCP X, but is now adapted to copters/planes in general
|
|
;
|
|
; The software was inspired by and started from from Bernard Konze's BLMC: http://home.versanet.de/~bkonze/blc_6a/blc_6a.htm
|
|
; And also Simon Kirby's TGY: https://github.com/sim-/tgy
|
|
;
|
|
; This file is best viewed with tab width set to 5
|
|
;
|
|
; The input signal can be positive 1kHz, 2kHz, 4kHz, 8kHz or 12kHz PWM (e.g. taken from the "resistor tap" on mCPx)
|
|
; And the input signal can be PPM (1-2ms) or OneShot125 (125-250us) at rates up to several hundred Hz.
|
|
; The code autodetects the various input modes/frequencies
|
|
; The code can also be programmed to accept inverted input signal.
|
|
;
|
|
; The first lines of the software must be modified according to the chosen environment:
|
|
; Uncomment the selected ESC and main/tail/multi mode
|
|
; BESC EQU "ESC"_"mode"

|
; Greatly increased maximum rpm limit, and added rpm limiting at 250k erpm
|
|
; Improved bidirectional operation

|
; - Rev14.3 Moved reset vector to be just before the settings segment, in order to better recover from partially failed flashing operation

; Timer 0 (500ns counts) always counts up and is used for
|
|
; - RC pulse timeout and skip counts
|
|
; Timer 1 (500ns counts) always counts up and is used for
|
|
; - RC pulse measurement (via external interrupt 0 or input capture pin)
|
|
; - Commutation timing (via output compare register A interrupt)
|
|
; Timer 2 (500ns counts) always counts up and is used for
|
|
; - PWM generation
|

|
|
;**** **** **** **** ****
|
|
; Interrupt handling
|
|
; The Atmega8 disables all interrupts when entering an interrupt routine,
|
|
; The code reenables interrupts in some interrupt routines, in order to nest pwm interrupts
|
|
; - Interrupts are disabled during beeps, to avoid audible interference from interrupts
|
|
; - RC pulse interrupts are periodically disabled in order to reduce interference with pwm interrupts.

|
|
; Motor control:
|
|
; - Brushless motor control with 6 states for each electrical 360 degrees
|
|
; - An advance timing of 0deg has zero cross 30deg after one commutation and 30deg before the next
|
|
; - Timing advance in this implementation is set to 15deg nominally
|
|
; - "Damped" commutation schemes are available, where more than one pfet is on when pwm is off. This will absorb energy from bemf and make step settling more damped.
|
|
; Motor sequence starting from zero crossing:
|
|
; - Timer wait: Wt_Comm 15deg ; Time to wait from zero cross to actual commutation
|
|
; - Timer wait: Wt_Advance 15deg ; Time to wait for timing advance. Nominal commutation point is after this
|
|
; - Timer wait: Wt_Zc_Scan 7.5deg ; Time to wait before looking for zero cross
|
|
; - Scan for zero cross 22.5deg , Nominal, with some motor variations
|
|
;
|
|
; Motor startup:
|
|
; There is a startup phase and an initial run phase, before normal bemf commutation run begins.
