Identifier PIN0 (1,2,3,4, etc) is undefined

Victor Youk54486

I'm looking to modify some registers using this kind of format:

P4DIR |= (PIN2 + PIN3)

However, the PINx gives me the "Identifier PINx is undefined" error. What is the proper include I must have? Thank you!

Hey Victor,

There is no actual definition for PINx (PIN1, PIN2, etc..), the most common way to use PxDIR, PxOUT, etc. is to use the BITx definitions:

P4DIR |= (BIT2 + BIT3)

Best Regards,

Matt J

Thank you! I must have been getting confused with another system.

IIRC, the 8032 has its port pins bit-addressable, so there migt even be a 'register' definition for each individual pin on soem compilers.

On MSP, PINx in a port is always equal to BITx, so there never was any need to define PINx in addition to the already existing BITx symbols.
