Pretty cool stuff! I have been using a WiFly to do http posts to www.thingspeak.com, but this looks pretty cool too! I'll have to dig out my pcdemnet board and try this out.

Jerry, I've been interested in a USB bootloader for awhile now. Not sure if this fits in with your plans. Even better would be a mass storage class bootloader, where the new firmware would be loaded if a new hex file was present. I haven't had the resources (mainly time) to look into either of these.

Roger that. I will continue to copy over the correct mpasm files to SF's directory.

I think this came up in another thread, but SF does look for the latest installed MPLAB, in the microchip install folder now though, right?

David, thanks for checking in on this. I really like to use SF vs PDS but have been trying ot use the last set of 18FKX622 series parts without much luck. I can use the 18F25K20 all day long but have yet to make some good attempts with these other parts. I was able to get it working in PDS so that w...

Peter, I had forgotten I had played with these a while back and could never get 18-bit mode working. Thanks for the great module. Unfortunately, I was unable to run this in SF (seems like it has been really buggy lately) on the 18F26K22 chips I wanted to use. However, I got everything up and running...

Peter, looks good. I am doing some thermocouple and I2C stuff now. I might have to look at pricing for these compared to the dedicated IC approach I am using now...looks like they are 1/3 the cost of the solution I am using now. mmmm, good stuff. Just curious what you have been using all those 18-bi...

Jerry, Great work. I am trying this out with 18F14K50. 1. Everthing compiles great. That's a good start. 2. I cannot run the "new" pc software on WIN7 64-bit. - "orig" bootloader pc software starts and recognizes device. Seems to program as well. But the cdc code doesn't seem to run. - I loaded the ...

Jerry, thanks for the link. I had seen this awhile ago and it was driving me nuts that I coudn't find it. Those routines will work perfect. I'll have to modify some code to work with this structured type array. But it is totally doable.

3x3 Matrix

All, I am looking at implementing some DCM matrix stuff very similar to code found here (http://voidbot.net/razor-6dof.html) for the Arduino. Is it possible to store a 3x3 matrix like they do here in SF. I am not sure what the best way to store this might be and am interested in any pointers if you ...
