HC11 or HC12 help libraries

[student]

Hi,

i am a student who need to connect a microprocesor to an IC devices which i need to configure throught an I2C or SPI bus. i can use either the MC68HC11 (writting in assembly using Bufflao compiler) or the MC68HC12 (writing using codewarrior).

Are there any libraries that i can add to the compilers so it is easier to use any of this buses (i only need to use one of them, depending on your answer...).?

Are these libraries free/how much does they cost?

Where can iu find this libraries?

Thanks

Hello Student,

I would advise to use the HC12, it is simpler, I think.
In your CodeWarrior, look for Processor Expert and see if it supports your product.

You have modules available on their website and it does most of the work for you
- init routines,
- read/write interrupt sub-routines (ISR)...

CodeWarrior is FREE for this size of application and Processor Expert is included in CodeWarrior.
You may want to get the latest CodeWarrior.
