You nailed it. Programming as expected now. Sincere thanks for your support.


I have been using this kit for about six years now and never experienced this. However MEProg does occasionally...

I have a nice little system which uses CanBus to Control 8 LED lights on a bespoke PCB.
I am using Darrel Taylors excellent SPWM_Int routines.

I have run this for several weeks now on a LABx2...

Hi Darrel

Thank you for the prompt reply, it was very helpful.

The code is now working very nicely.

By the number of posts, instant interrupts are very popular. I have a number of projects...

Hi All,

Just getting into using Darrell Taylors Instant interrupts with 18f4580

Had about half a dozen compile errors initially but quickly resolved them. However there is one final error...

Hi Ingo,

Well spotted on the major bug . I dont know how many times I checked that - obviously not looking properly - either I was misled by the bogus bus activity which convinced me the output...

Hi Ingo,

Update for you,

Received two 18F248 today. snatched half an hour to quickly try out, but no bus activity at all. getting the same results as for 18F4580 otherwise.

Also tried using...

Hi Ingo

Code wise, I am doing the same configuration with the exception that my BRG con values are for 125Khz and 16Mhz. Beyond that I am setting data byte values for tx. I will send you code for...

Thanks Joe S for the links, I already looked at most of Microchip data sheets and Application notes. Lots on M2510 but not much on ECAN.

Just checked the 18F4580 Errata, but there is nothing in...

Hi Ingo,

Thank you for coming forward. I am not having any success in achieving a Can transmission in Normal mode. I have two 18f4580s connected together on 400mm of twisted pair and 120 ohm ...

Hi Folks,
Anyone got experience using CAN interface on the 18F4580 or similar microchip device ? Lots of resources available using 16F876 etc with 2510 external interface but had no success...
