MQX 4.2 & SPI driver for SPI3 module

BlueJay — Wed, 17 Jan 2018 09:59:59 GMT

Hello everyone,

since SPI2 Interface is not available on VF3xx we need to use the SPI3 Interface.

Now I am looking for the SPI Driver on MQX for SPI3 module. But MQX only provides SPI Driver for SPI0, SPI1, and SPI2.

Is it correct that MQX does NOT Support SPI3 Interface ?

I need to implement the SPI Driver by myself ?

Many thanks for any clarification or hints about this issue.

Bluejay.

Hi Bluejay:

Yes, you are right. No SPI3 support in current MQX package. You need to implement it by yourself. sorry for the inconvenience that maybe cause

Please refer to the MQX_io_user_guider.pdf for more details.
Chapter 9 SPI drivers. This chapter describes the SPI driver framwork

Maybe the following file will be involved.

io/spi/*

init_bsp.c

init_spi.c

user_config.h

Daniel
