Hello Matrix team,
Have you got any idea about the problem between Timer1 and Timer2 ?

I confirm that the problem appears during simulation and when using control board.

I don't know what to do.

Hello Benj,
I tried several tests tonight.
First , I removed Interrupt on Timer0, keeping the interrupt of Timer1 on external clock RC0. No change, motor left affected, reversed.
Second, I put back the 2 interrups, on both timers, but both on internal clock at 2441 Hz, motor left affected.
3rd test ...

I agree with you that Timer2 should not be affected by use of Timer1, that's something very disturbing.
I did not try to run Timer1 without Timer0, I'll give it a try this evening.
About clok sources, I'm not simulating, my program is running on my mobile plateform, with 2 motors and IR odometers ...

Hello Benj,
Still working on my robot, I found a new problem.
Here we are, my project runs on a PIC 16F877a, I am using PWM component to run motors 1 and 2 separatly.
I intend to measure distance of each wheel using odometers. I wanted to use interrupts, one wheel distance counted by timer 0, the ...

Thanks Benj,
Finally, after a couple of bad results, everything's clear, uploading ok, with the right configuration, and RS232 working well.
At last, the mess I did was due to the fact that my PPP setting did not stand while doing all the tests. I should have check that, but you know ...
Well, now ...

Right Benj,
So I have to put the configuration into an additionnal C code control box ?
Actually I tried last night, but every time, what I've got was a compiling failure from C to asm :
D:\Matrix Multimedia\Flowcode V3\Exemples 16F877\TUT_09_printf.c(303): error: missing semicolon
D:\Matrix ...

Thanks Benj for the answer,I understand that the expert configuration screen is from PPP software.
Unfortunatly, the 16F877 on which I try to load my programm is on a developpment board I built. And you know what, I have only the serial port to upload my program. And it seems to me that PPP has been ...

Dear MatrixMultimedia team,
One more post on this forum for tonight, I would have two requests about new components, the first one would be an I2C sonar sensor like the MSU10 or SFR08 , and the other would be the I2C compass CMP03 . Both of these components are widely used for personal robots and ...

Hi MatrixMultimedia team,

I've got another RS232 problem ...
I recently purchased FlowCode, because of my poor software programming skills, Flowcode sound a lot easier.
However, to debug my programs, which run on a PIC16F877A CPU board that I built, I use the RS232 trhough a MAX232 connected to ...

Hi everybody,
I'm having troubles when compiling Flowcode. It happens sometimes on some programs, while on other it happens every try.
The error message is
"Error : Access Violation at 0x7C92084B (tried to write to 0x00030FFC), program terminated.

Have you got some ideas ?
