hello,
i just tested the program with the 16f88 but it s not working , there are some error messages.

dont know exactly what to do next
can u give me some advices please??
thanx

thank you very much , it was the trisb=0000001 command that resolved the problem. it works as expected but one more thing is not right, the portb.6 output 1.62 volts when the program goes through...

my program is working fine but i just need to learn more about interrupt so i can make it better. by the way i started my project very early but not early enough (last summer).

about the small...

hello
i woulk like to know how can i activate an interrupt digitally instead of using a switch.
because i wrote a program with need to jump to the interrupt when one of the 4 portb is low,
i.e. if...

hello,
i wanted to test an interrupt in a simple small code , i found a code on the internet and modified it and got this:
@ DEVICE INTRC_OSC, LVP_OFF, WDT_OFF, MCLR_OFF

DEFINE OSC 4

hello,
this is a peace of my code, the main routine called main is detecting object and avoiding them and the interrupt subroutine is called start.

basically its a robot which detect and avoid...

hello every body
i m trying to program a small robot which will detect objects and avoid them and will also avoid edges.
i managed to write two separate codes, one for the edges detection and...

those 6 lines allowed me to use an accurate inside clock and to use all pins as digital input or outputs:

DEFINE OSC 4
INTRC_OSC_NOCLKOUT
INTRC_IO
OSCCON=%01101000
ANSEL=%00000000 ...

thank you so much. you are a star
finally everything is working with internal clock and measurements well displayed on the lcd.

wasn't that easy to understand the data sheet but because of all of...

what do you mean by check porta.0 , read post2 and 4 ????? do you mean that the porta.0 is analog and I shouldn't use it for digital signals input????

anyway , I moved the echo signal to...

i just tryied to use the external clock again.
but it is still not working.

any one with an idea, please ??????

hi
i just tested my port with few led and they work fine, inputing and outputting.
but the srf04 is still not working.
I have no idea of what is going on.

anybody with an idea????

good idea but how can I do it???
how can I disable the ADC and comparators in a 16f88???

hello everybody

I have few problems with my ultrasonic ranger the SRF04.
I managed to make it work with a pic 16f84 to measure distances in inches and centimeters and display the results on a...
