Hi.
I want to know that there are any MCU which support 9 bit SPI interface. Do you know that? I will wait for your answer. Thanks.2013-12-03 04:07 AM
Do you mean any MCU at all, or is there a particular family/subset you're interested in?
Have you looked at any datasheets?2013-12-03 06:32 AM
I got a couple of SoC designs that work from 1-to-32 bits. The STM32F0 and STM32F3 parts support 9-bit configurations.
On other parts you can play games with sending 9x 8-bit bytes, or simply bit-banging the bus.2013-12-04 12:21 AM
It's possible to bit bang 1 bit and send 8 bits with hardware, tricky but works.
