just looking for some more in depth information on the ISP commands regarding the AT89S52. I a building an ISP programmer using another AT89S52,... Be warned, there are details of the timing which are neither listed in any datasheet nor application note! I have the ISP programmer from Atmel and can tell you, that this beast produces signals on the reset and clock lines which do not comply with the datasheet specifications. So, I would highly recommend to choose the atmel's ISP programmer. This does not mean that you have to buy something from atmel, because software is free and schematic can be found in the www. Kai |
