MSP430FR2355: Error #20: identifier is undefined

Carlo

Part Number: MSP430FR2355

Hi E2E,

Good day.

Our customer is using the MSP430FR2355 and they're getting an error in the UCSCTL designation. Is there something wrong with the code? Please help in figuring out the proper way of labeling this for MSP430FR2355. Please see attached image of the code and the error when debugging.

Regards,
Carlo

It looks like this code was written for an F5 series device. [Ref F5 User Guide (SLAU208Q) Chapter 5 "UCS"]. The equivalent for the FR2 is the "CS" module [Ref FR2 User Guide (SLAU445I) Chap 3 "CS"] There's a lot of overlap, but some of the fields might have moved.

Also, the FR2355 is only rated up to 24MHz (vs 25MHz for most of the F5 series), so the FLL and TimerA constants will probably be a little different.

An example for running the FR2355 at 24MHz can be found in Example msp430fr235x_CS_09.c here:
