FWLib V1.0 to V2.0 migration steps

AN2776

12/20

1.

2.

“I2S” was added in the configuration parameter to indicate that it can be used for SPI

3.

The function format is updated as follows:

SPI_

e.g.: SPI_

Table 3 provides the list of the impacted functions.

If you are using any function listed in the first column of Table 3, update the prototypes and

parameter name to the new names given in the second column of the table.

Example: Typical code for SPI interrupt and DMA configuration based on FWLib V1.0:

Using FWLib V2.0, this code becomes:

SPI_I2S_ITConfig

(SPI2, SPI_I2S_IT_TXE, ENABLE)

Note:

peripheral.

SPI-specific functions

The functions not listed in Table 3 where not modified and are specific to the SPI protocol.

1.

I2S_Init(SPI_TypeDef* SPIx, I2S_InitTypeDef* I2S_InitStruct)

2.

I2S_StructInit(I2S_InitTypeDef* I2S_InitStruct)

3.

I2S_Cmd(SPI_TypeDef* SPIx, FunctionalState NewState)
