Now you connect this little gadget you have made to the thing with SPI that you actually want to test.īecause you designed the gadget and wrote the protocol you can engineer the protocol to be the 'best' thing you want to use from the PC software you will then write to drive it. The only things tha connect to the USB ports and don't require chips are those little lights used to read while using notebooks.

This chip in turns receives the Data and changes to the proper ps/2 protocol. Obviously you include a mechanism to get the reply bytes back too. the ps/2 protocol is a very simple one but the USB is not it requires a chip so whatever connects to s USB port has to have a chip. It then talks on using its own SPI interface. You then define some protocol the PC and AVR agree on where a command such as 'S34,56,78' sends those 3 bytes in turn to the SPI (or something like that anyway!). In all cases the PC view will be a 'UART' so you can use existing terminal software to talk to it.

To be honest if I wanted 'SPI out of a PC' what I'd actually do is implement a small translation board using an AVR!ġ) Just an AVR then a USB-TTL cable connected to its UARTĢ) An AVR+MAX232 then a USB-RS232 cable connected via the MAX232 to its UARTģ) An AVR+ converter chip then just wire PC USB to converter USB and on the other side of the converter connect to the AVR UARTĤ) A USB enabled AVR that can be programmed to do CDC-ACM class
