is posible use the logicator for programing a normal pic ?
(means not picaxe)
(means not picaxe)
programmin a normal PIC ?
- Thread starter diegosantos
- Start date
Actually Logicator can but it only supports a limited ranges of PIC types, requires configuring for such use, requires the purchase of programming hardware, does not offer much above what a PICAXE provides for ( and generally less ) and is primarily supported for legacy users who were using PIC before the PICAXE arrived.
So; yes it is possible but it is not an option which would be recommended.

A year ago Chap over on another forum was seeking a 12F675 microcontroller Free Flight Timer and kindly offered payment provided that it was not Picaxe.
Suffering greatly from inverse snobbery I made a simplistic Picaxe program and posted it in another section of that forum.
But as a bit of a challenge I tried to use the Picaxe wizard to convert it to Pic 12F675 native code and program one with the Picaxe Programmer. So, being me, of course I posted it in the Picaxe section, well he didn't want Picaxe so he certainly wouldn't want to know about the Wizard.
I have dug out the breadboard that still has the Picaxe 08M2 and a Pic 12F675 and can swap the chips without discernible difference in operation.
The ASM code at 2000 lines?? is too long for the Forum so truncated, it shows 629 but is working on a 675 as in the photo.

Code:
'Free Flight Timer Requirements
'1. When switched on, Timer is set to open throttle position (default)
'2. Engine is started, short button press starts timer, LED lights timer is armed.
'3. Time elaps, engine is cut, throttle stays low until switched off.
'Response
'Switch1 on GPIO3,pin4 Start Timed engine run and also on Switch1
'Switch1 hold down while switching ON to record new Time
'Steady LED = Timer is running
'1 second flash when new time is being recorded
#Picaxe 08M2 ' delete the 2 in this declaration if using 08M
eeprom 0,(15) ' pre-loading Time elapse into non-volatile memory
servo 1,200 ' servo to high, initiating servo command
start:
if pin3=1 then main ' Switch for new Time at Switch/ON only
start2:
servopos 1,200 ' Hi throttle, (default)
pause 22 ' wait for GO and time for servo RC frame
if pin3=0 then start2 ' Initiate Time at Hi throttle
high 2 ' Timer running, Steady LED during Hi
read 0,b0 ' Get Time, in seconds from eeprom
for b2=1 to b0 ' Count off the seconds
wait 1 ' 1 second
next b2 ' Inc counter
low 2 ' Time finished LED extinguished
Fin:
servopos 1,100 ' Low throttle held till switch is OFF
pause 100 ' Servopos works in background,needs time
goto Fin ' Stay Low till switched off
Main:
servopos 1,100 ' Indicates Changing Time
high 2
pause 500 ' Half second ndicator
low 2
pause 500 ' Second half second
b2=b2+1 ' Added to b2
if pin3=1 then main' Switch to end new Time
write 0,b2 ' Replace old Time in eeprom
low 1 '
goto start ' End of new timing. Switch OFF
