ikalogic said:I want to build an ISP programmer that attaches to the serial port of a PC.
I have already made a parallel programmer here:
**broken link removed**
But Parallel port is disapearing, slowly but surely, so i want to find a long term solution, either USB or SERIAL. I am able to build any required program (under WINDOWS)
I thought i would start by putting my first target on the SERIAL port (since there exist many USB to serial adapters out there..)
soo.. here is where i stand!
So basically you're trying to reinvent the wheel?.
But, as Bill says, essentially both serial and parallel are disappearing, so you need a processor solution, USB to serial adaptors don't really work for non-standard (actually non serial port) uses of a port.
