My C deal with Microcarl
Hi Jörg, The '168 XML files are correct nowadays, but back then the 168 stepped vectors by 2 bytes, I have old installs files but don't really want to install an old version to...

I just found the offending code in a backup archive (who needs subversion (me...

My C deal with Microcarl
Well, I'd still be wary. I did an ATMega168 project last year and had problems with interrupt vectors. Worse still, it was code that used to work. I checked the headers and all...

My C deal with Microcarl
Hi Dean, That sounds like a good idea, but is probably a bit counter to the apparent plan to put device-specific info into the AVR Studio XML files. I'm still not sure how they...

My C deal with Microcarl
To revisit a much earlier part of this post, you have about twice as much code as you need ;-) /*Led flashing program, uses pb1 as led output on Mega88*/ /* Clock is 1MHz...

Reliable usart comms without 'magic number' oscillator
Just one little refinement for those who haven't come across it before. Don't just calculate the baud-rate divisor based on baudrate pre-scaler and clock, add .5 to it to get the...

USB uding FTDI245BM
Just a quick check, have you fitted the 6MHz crystal and capacitors to the 245? I used the FT245R, Oscillator integrated, USB Bus resistors integrated, EEPROM integrated, AVCC...

Total newbie in trouble, reading coils
Whilst higher frequencies allow smaller inductors and smaller pucks, it would be better to use smaller capacitances as the area of the puck is related to the coupling with the...

Wireless Data Transmssion
I did a remote control recently and came up with a tricky scheme to preserve DC balance. I split each byte to send into 4-bit nibbles. I then code a 1 as 2 bits 10 and a 0 as 01...

USB uding FTDI245BM
Hi Guys, Really Erasing the chip with a hardware programmer like AVRISP can clear the fuses and bootloader space. The Bootloader code mentioned fakes an AVRISP, but when it gets...

Total newbie in trouble, reading coils
I think I get the picture, several sensor locations, 'buttons' of several different resonant frequencies which may or may not be present at those locations. What you are building...

BIG PROBLEM:Convert compiler defined string in unique number
I think you'll be better off in the end just biting the bullet and setting up a bunch of #defines. For each C file you can use 2 digits for the File ID since you only have 30....
