Hi to everybody,
i'd like to make a sipmle MIDI piano that should be connected to my computer. Which ST7 have implemented the MIDI serial protocol? I thank you2004-08-09 09:48 PM
ST7 do not have any protocol by the name MIDI serial protocol. But have I2C, SPI etc. Could you explore more about the MIDI serial protocol?

You can use ST7 micros with SCI - Serial communication Interface (e.g. devices like ST72F264 or ST72F521). The SCI can be interfaced to create MIDI interface and I/Os can be programmed as your Piano keys.
Hope this helps, ParveenG2004-08-12 11:49 PM
Hi ParveenG,
I have tried with the SPI protocol with a st7lite09, as you can find in my other question, but after a byte trasmission i have 5 volt fixed at pin 3 of the port B (used for the SPI trasmission in master mode). I should have 0 volt. I have tried in several ways, but i couldn't find the way to reset the pin 3 of the port B. Something is wrong? Have you a solution? I thank you
