That particular pull-up one is a 'gotcha', in the CCS code, where it only works correctly with the drive disabled, on transceivers that do have internal pull-ups....

So, now you need to be doing so ...

He is actually compiling for the F, not the LF.

Since it runs on the F at full voltage, and the device ID for the F and LF are the same, we know the problem is with the voltage, not the code.

I ...

OK. So as I read it, you can compile and use the code OK on the 'F' variant, but the compile is halting on the 'LF' variant?.
If so, the first thing you need to tell us is the compiler version?.
Any ...

What is the Vdd voltage on each PIC, and on each type of CAN bus
transceiver chip ?

The PIC 18F2685 has a VDD voltatge of 5V and the 18LF2685 has a Vdd voltatge of 3.3V

The 18F2685 is connecte ...

What is the other PIC?.

The 2685, has the ECAN peripheral, so you really should be using the 18F4580.h driver.
The other pic is the 18LF2685

Hi;

I am doing a project where two PIC have to communicate between each other using the CAN protocol (can-18xxx8.c , in the drivers folder in PICC).
I have tried to establish (turning on & of ...

Just use a text search engine on the files in the CCS drivers directory on
your PC. Search for 'rectangle'. You will find a few functions that
draw a filled rectangle with the specified color. ...

Great, it worked perfectly. Thanks guys.

The problem is that with this "blank display" code that I have shared doesn't allow to blank neither the display not the buffer in random square locations of the display, as it isn't meant f ...

Hi
I am currently developing some bargraph (8 LEDs) made with a shift register and, in order to test it i have developed to following code.
The problem I have encountered and that I need help with ...

Do you guys have any idea on how to modify the attached code in order to only clear a specific area of the display and not the whole screen? I have tried several times but haven't successfully found a ...

Thanks,

By disabling the fuse LVP works perfectly

this is how my fuses are defined

#include <18F2685.h>

#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale

I've tried by disconnecting the programmer and still doesn't get to the high level. Other pins do work. I also tried by changing to some other 18LF2685 so the error is not in the PIC.

thanks

Hi,

I am using a 18LF2685 PIC and recently I have tried to turn on some LEDs with the pin RB5 with pin number 26. When trying with some other pins I get no problems but with this one I can't get it ...
