P89C51Rx+/P89C51Rx2/P89C66x/P89C6xX2/P89V66x / ISP Programmer
« on: November 12, 2009, 01:02:22 am »

I program some P89V664 soldered on the electronic board, I use a Future Design USB-ICP programmer, but it don't seems to be a good quality programmer...So I'm looking for a programmer for the P89V664 compatible with Flash Magic and ISP programmation. Do anybody use an other programmer?



I've a P89V664 on a board and I use an USB-ICP-8051-ISP to programm the microcontroller, I saw all the post and I alway's got the message "Unable to connect at the specified baud rate...." I've tried to reduce it but it has no effect, I send a "U" by the terminal and I got the echo on the oscilloscope. If someone has a tips, perhaps there is a pin to connect that I missed, if sommeone have a pict of his ISP schematic...

Thank you!
