Hello,
I can't program a mega644 with the USB-ISP programmer I bought from MCS , some years ago. When I connect the programmer to a Mega8515 board , it works perfect. After this , I programmed the Mega644 with a Leaper48 programmer , I loaded it with a small led program , so I could see the Mega644 was working. The Leaper48 programmed the Mega644 perfectly. I verified the board connections over and over , they look fine as Mega8515 and Mega644 have the same program-pins at the same place. So .... am I doing something wrong or so? With a logic probe , I see some pulses to mosi , miso and the reset. It looks like there is a very short time of communication. When I want to go to the "Program chip F4" , it says it can't read the ID of the chip. The Bascom version I use is 2.0.7.6 and the computer has XP SP3 operating system. Can someone help me here?
Many thanks,
Ron,
