Overview of Code:
The program for the PIC is broken up into the three sections: Main program, Low Priority Interrupt
Service Routine, High Priority Interrupt Service Routine
INITIALIZATION
Configuration Bits: Oscillator set to HS (10MHz)
Disable all other bit word settings
Configuration Variables: Motor speed Max = -3200rpm to 3200rpm
Motor PWM period = FF (255 clock cycles)
Max motor duty cycle = 1000
Fin position = 3000 to 5000 (4000 is initialized position)
Baud Rate = 57.6k
Internal clock = 10MHz
MAIN PROGRAM
While loop overview: Wait for new command to be sent
Poll motor speed and correct if necessary
Send out PWM signals to three fins
Returns motor speed and PWM signals
Processing Command: Once command is received from DimmPC it is searched for each element
Format of command: aXXXXbXXXXcXXXXmXXXX
(All or portions of the command may be sent)
Each element is saved into a variable to be implemented in the ISR’s
If “x” is sent new speeds are not returned
If “e” is sent speeds are returned
No Command is sent: Until a new command is received the speed is continuously polled and updated
After each speed check, the speed and PWM signal is returned to the user.
HIGH PRIORITY INTERRUPT
Triggered by Fins Flag: 6 step cycle: Set fin a high, Set fin a low
Set fin b high, Set fin b low
Set fin c high, Set fin c low
One step is implement each ISR is called due to
Triggered by command: When a command is received, the receive buffer triggers this ISR
The ISR then saves and receives the data into a command buffer
The received command flag is set so the main while loop will
process the command when ISR exits
LOW PRIORITY INTERRUPT
Triggered by Motor Flag: Reads the decoder chip and exits ISR (repeats 10 times)
Read decoder 10 times (multiple reads decreases error)
Convert data to rpm (freq of 10th read = 10.1Hz)
Compare with goal speed to get speed error
Calculate speed comp based on err
