Issues that need attention when initializing SPI of C2000 series 280049 chip [Copy link]

When the 280049 chip uses TI's library function, the register settings do not change after SPIA initialization, all are 0. At this time, you need to enable SPIA or SPIB. This problem has troubled me for a long time. Finally, I compared the two projects and found that

SysCtl_enablePeripheral(SYSCTL_PERIPH_CLK_SPIB);
This should be changed to SPIA, and then there will be no problem with initialization. I have to say that this kind of thing is really a pitfall
