STK500 and Tiny11
2005-03-15 by leon_heller
Has anyone successfully used the STK500 to program a Tiny11? I've checked the connections several times but can't find anything wrong. Leon

Dave, Sorry to hear you're having a bad time. A suggestion.. Download the CV-AVR demo, compile your code on studio, and then use CV-AVR to program the chips. I have no end of hassle with the bloody avr studio programmer, but CVAVR always seems to work perfectly. Paul ----- Origin

When you pick up the 4 byte value you start from the first address of the array of bytes. So, this gets to the concept of 'endian'. In a 'little endian' architecture the low order byte will be stored first followed at higher addresses by higher order bytes. In the 'big endian' ar

A common practice, where a bit of inefficiency is OK, is to send numeric information larger than a byte is its HEX-ASCII or Decimal-ASCII form, rather than, say, 4 binary digits. That way, there are no byte-order or bit order issues for the other end of the link to have a-priori
