Hello,

I have a rather strange question about IDE options. I have this auto expand option Unticked in Editor options. But when I reopen a project, all the tabs open expanded all the time. So i kee ...

Hello again.

I successfully made the synch with IO as Thelmah suggested. Thanks a lot. The difference is noticable in a slow motion cam.
Now I am trying to make 3 PIC synchronization since I wi ...

OK got your point Thelmah but this only solves the problem "starting the operation at the same time".
How do you continue to be in sync mode after that until the end of operation, that was ...

Hello;

Thank you for your quick responses. My 2 dsPICs have PID loops in cascade, both controlling speed and position in closed loop. The motors are small dc motors with optical encoders.

Ttel ...

Hello;

I have a test bench concerning 2 dc motors. I need to run these motors in sync since they need to lift some weight from 2 opposite ends. In order to move them in sync, I suspect that the PIC ...

Hello;

I have worked on this matter a little more. First I changed the Loader Size to 4FF and thought it was working but i was wrong, its still the same.
I took the symbol map of the bootloader p ...

OK.
A basic test with your compiler, shows where the fault is.

The application code must always start on a page boundary, and the code in the bootloader needs to fit in the space allocated for it. ...

OK.

Your last comment is interesting. Think about it. Interrupts imply a hardware 'call' to a specific memory address. If there is no code at this address this will almost certainly completely cras ...

since this PIC is the slave, how do you know the Master is sending ? Does a scope confirm data IS being sent to the Slave ??

Yes I am sure. I did 2 tests. First I checked with oscilloscope if I am ...

#BUILD STACK=0x200

That should be large enough for most normal use.

Hello.

I tried your suggestions, the RAM use increased to 26% but its still the same. The code normally runs but interrupts ...

OK, so that's not it....
next idea...
Maybe you need to increase the 'stack' size ? I recall some of these 'high powered' PICs need you to increase the size of the stack. The more complicated the co ...

OK I don't use that PIC but just quickly looking at your code..

...this doesn't look 'correct'.

#INT_SI2C
//!#int_ssp

You commented out the official CCS PreProcessor directive name and rep ...

Hello.

I have a strange behaviour with dsPIC30f4011. I loaded the CCS supplied serial pcd-bootload code through PICKit2. After that, I downloaded my application through serial port with pcd_bootlo ...
