The communication seems "reasonably" straightforward. But what about timing. For the PIC18F4553 connected to the PC via USB, this is fine. But once this is programmed, this will take a few s ...

has anyone managed to get a piar of pics programmed via a single USB connection? I have two pics which currently "talk" via i2c, one is an 18F4553 and the other an 18F4650. The 18F4553 can ...

Which is the best header file to use with a PIC18F4685 for CAN ? I'm using the ECAN module direct, so no use of any MCP* devices. Is the can-18xxx8.h compatible, or is 18F4580.h better ? Or do neither ...

Having done further tests on this using flexhex, it seems that mmcd.c library looks only at the "Physical" layer (obvious really), and that the "real" boot sector needs to be read ...

I've tried a number of different #USE_SPI settings and none seem to alter that I dont read the correct values from the SD Card. the "FORCE_HW" isnt supported in 4.057

I'm guessing the onl ...

Thanks for both your help! I'll investigate further. I still dont think the mmcsd.c driver is working properly though.

Well, if I read from the SD card using mmcsd_read_data, my offset is an int32 based value, starting at 0. When I use this function and read the first 5 bytes I get :

EB 58 90 4D 53 44 4F 53 35

I have an SD card, formatted FAT16 on a PC. I'm just doing some tests on read/writes to it and one of the tests is to find the volume name on the card.

When I search for the volume name ('MYDATA') ...

Presumably then, this is a bug in the fat.c library CCS supply. I'm on compiler 4.057

I'm using the fat.c library supplied with PCH and I appear to be able to write files to an SD Card. But I cannot see those files when I put the SD card in my PC. I can create files from the PC and not ...

I tend to agree. I used their IDE and really didn't like it at all. MPLAB isn't brilliant, but it certainly better than the CCS one. And infinitely cheaper!

Great, so don't actually do it in a logical manner, do it in a quirky "CCS" manner.

Maybe that explains why their shipped files often don't compile and why eventually you end up rewriting ...

I've decided to split my source into separate .c/.h files and before doing this I'm trying to build the MCU project example given by CCS.

Everything compiles, but the linker fails ...

Clean ...

Thanks, I will try that first and see how I get on. I am new to CAN and may I ask another quick question. The PIC I'm using is an 18F4685, which uses ECAN, the display I want to talk to is CAN 2.0B. I ...

I'm currently trying to interface a PIC18 based datalogger to a CAN based automotive display. This requires messages to be sent at 1Mbit. I'm currently using a PIC18F4685 at 20MHz, with an MCP2551, bu ...
