Peter -

Didn't realize SE had been updated too. Let me take a look...

Are you using the SE version of the compiler? If so, it's a couple of versions behind the released one, and it has issues with the K22 that have been fixed in the latest full version. I can't vouch for the include files from Miles, but when using the ones produced by the SF SystemConvert utility and...

it seems that I can read and write the registers, but the time is not running (changing) If you have verified that the I2C bus communications are correct and that you can indeed talk to the chip (try reading/writing to some of the scratchpad RAM bytes), then it sounds like the oscillator is not run...

Glad it's all making some sense. Read the datasheet, even if the code has been tested You may find this with a number of libraries. There are so many different chips out there it would be a full-time job just trying to keep up with all of them. While most of them are pretty similar, it seems Mchip j...

I'm running it with a different chip (and no sensor), but as long as I specify a port pin that has a pullup and shut off the analog function for that pin, then ds18b20.find() returns false as it should.

If I specify an unused analog or floating pin, then it hangs.

Yeh Garry, you mentioned that. I've never used the OW module, but I can see where Find() could get hung up if the hardware's not functioning. I could be wrong (and haven't actually checked this), but the outer 'repeat... until (LastDiscrepancy = 0)' in OW.Search() looks like it'll hang if the pin re...

On the 4620, pin RE0 is also analog input AN5.

Add a call to SetAllDigital() (found in utils.bas) before the SetPin() call. The default version of SetAllDigital should work ok for this chip from what I can tell.

Very few chips are spec'd such that an input pin can exceed Vcc by more than a few tenths of a volt. Usually there's an input clamp diode on the signal pins to Vcc, so if you shut off Vcc the clamp diode conducts and powers the chip via the input line. How about tri-stating the SPI signals (or setti...

Glad you found it. It seems to calculate the delay values wrongly, in the end I simply calculated the correct value myself and used that as the argument for SetBaudrate. I don't know if it isn't being passed correctly but when you look at the calculated values it seems to be ignoring the Clock setti...

Without seeing the actual code, it's hard to make specific recommendations, but here's some general ones. There's about 25 bytes or so of sytem variables which you can't do much about. If you use interrupts and you have a 'save(0)', you need ~2x that to store the context, and if you use both high an...

It seems I violated one of the cardinal rules of software development... don't make any changes after testing (no matter how simple), and found out once again why that rule exists. It seems I added a compile-time check to verify some '#define' settings in the USBCDC file after I had done most of the...

I updated the library to v1.4.1 to fix the register initialization issue identified by Graham and RangerBob in the thread http://www.sfcompiler.co.uk/forum/viewtopic.php?t=1470 Normally, I wouldn't post an update so soon, but since this one can be a show stopper if you're using a bootloader, I figur...

Dang, Nathan. It sure looks like you've got your bases covered. Of all the junk I have laying around, one thing I don't have is a 4550. I took a look at your latest ClearRegisters.bas, and the Mchip HID bootloader hex file (USB Device - HID - HID Bootloader - C18 - PIC18F4550.hex), and one thing I n...

Have you seen http://www.sfcompiler.co.uk/wiki/pmwiki.php?n=SwordfishUser.MultiArray ? Something like that could even be extended another dimension if the data is in ram, but unfortunately, this method won't work with const data since you can't initialize an array of const structures. I think you mi...

I just posted my updated version of the SF USB library over on Digital-DIY ( http://digital-diy.com/Download-document/87-SF-USBv14-Library.html ) Features include: - support for all current 30 18F USB devices, including: 18F2550, 18F4550, 18F2553, 18F4553, 18F2455, 18F4455, 18F2458, 18F4458, 18F2450...
