Save your headaches and look to getting a PICKIT2 from MicroChip.

Save your headaches and look to getting a PICKIT2 from MicroChip.

Hello Dave,
pickit buyed and running, I've too mounted a 18 pin in a board connected with the ICSP signal.
It's all ok with pic 16f628, but with 18f88 have this alarm message


The code :

TRISA = %11111111 'RA.0:3 Input
TRISB = %00000000 'all PORTB output

ANSEL=%00000001'only porta.0 is analogue
ADCON1=%00000010'right justify the result(top bits are read as zero)
CMCON = 7 'Turn off comparators

adval VAR BYTE
i var BYTE
RPM VAR BYTE

' Define ADCIN parameters
Define ADC_BITS 8 ' Set number of bits in result
Define ADC_CLOCK 3 ' Set clock source (3=rc)
Define ADC_SAMPLEUS 50 ' Set sampling time in uS
PAUSE 500

loop:
ADCIN 0,adval

serout PORTB.6,n2400, [$FE, 1]
serout PORTB.6,n2400, [$FE, 2, "pressione ", #adval]
serout PORTB.6,n2400, [$FE, $C0, "giri", #rpm]

IF adval < 90 THEN
HIGH PORTB.4
endif

IF adval > 120 THEN
LOW PORTB.4
endif

COUNT PORTA.2,250,RPM
for i = 1 to rpm
toggle PORTB.5
PAUSE 25
NEXT i
LOW PORTB.5
GOTO loop 'repeat

Any help will be apreciated,
Thanks a lot

Hi Dave , I'm at home now, but have the original one from MPASM 8.10 ans pbc Pro 2.50. MicoCode Studio Plus last release.

Tomorrow (now it's 23,20 pm) I'll post the file.

tnx
