Hi there,

I have problems with the ISP. All the pulses are send well. I can see it in my oscilloscope. All times and frequenies are ok.
The chip is ok and works fine in parallel mode. I mean it's not burned.

In the datasheet there is something like RD_INT or READ_INT command but this is command is nowhere. Does anybody knows how can I talk via ISP whih this chip.

Ah, As I send the pulses at MOSI (0-5V) by clocking the SCLK, I see some pulses at the MISO, at the falling SCLK edge but the voltage is (0-1V).

Thanks.

Michael.

You have posted in the wrong forum. This forum is to discuss projects that are or will be in the AVR Academy. Please delete your post and put it in the AVR forum, you will get better help there. And I think you need to review your acronyms. ISP (in most context found here) means In System Programmer. I don't think the ISD1730 supports ISP. I think you mean SPI, Serial Perifial Interface which will interface it to a uC and if it has internal flash program memory you might beable to use ISP. All AVR are ISP capable.
