Send data from target thru ISP3 to Delphi ??

Hello,

I would like to send datas from target ATMEGA and SPI connected to the ISP3 programmer, and receive them on computer under Delphi program. Is it possible ? what components to import to Delphi 5 ?

The idea is to help for debug, as I have not the JTAG interface on my project...only the ISP connector, so nice if I can send out bytes datas to control...

Thanks,

In this case, it would be nice for your company to product a new product, very simple, on USB out to connect on the SPI pins by the standard ISP connector, and Delphi components to exchange datas with Target board via SPI !
The advantage for all customers would be to use USB interface very easily, without modify the hardware, with standard AVRs and only ISP connector

There was a BusPirate (27$) compatible AVR project called BusNinja, which could allow you to issue i2c, spi and some other commands over serial line. I have just checked and site is down, but you can access it's files here: https://github.com/jobytaffey/bus-ninja. It shouldn't be hard to interface it with any serial component for Delphi/Lazarus/FPC.
SPI commands and serial communication then looks something like this:
