Detailed Description

SPI library for STM32Fxxx - http://stm32f4-discovery.com/2015/07/hal-library-08-spi-for-stm32fxxx/.

It supports all 6 SPIs in master with 3 Lines Full Duplex mode

Default SPI settings

All six SPIs work the same principle by default:

• Master mode
• 8 data bits
• Clock polarity low, data sampled at first edge, SPI mode 0
• Prescaler set to 32
• Firstbit MSB
• Software SS pin configure
• Direction is full duplex 3 wires

In case these pins are not good for you, you can use TM_SPI_PinsPack_Custom in function and callback function will be called, where you can initialize your custom pinout for your SPI peripheral

Possible changes to each SPI. Set this defines in your defines.h file.

Change x with 1-6, to match your SPI

//Default prescaler
#define TM_SPIx_PRESCALER   SPI_BAUDRATEPRESCALER_32
//Specify datasize
#define TM_SPIx_DATASIZE    SPI_DATASIZE_8BIT
//Specify which bit is first
#define TM_SPIx_FIRSTBIT    SPI_FIRSTBIT_MSB
//Mode, master or slave
#define TM_SPIx_MASTERSLAVE SPI_MODE_MASTER
//Specify mode of operation, clock polarity and clock phase
#define TM_SPIx_MODE        TM_SPI_Mode_0
