TM4C1294XL SPI和SOFT_SPI的差别?

在TivaWare_C_Series-2.1.4.178/examples/peripherals/ssi/ 下同时看到了soft_spi和spi 请问这两个有什么差别?

xyz549040622:

顾名思义,一个是硬件SPI,一个是IO模拟SPI。

Susan Yang:

是的。
This example provide the same functionality using the same pins as the spi_master example.As such, it can be used as a guide for how to convert code which uses hardware SSI to the SoftSSI module.
