register and bit names as they appear in the datasheet

There are many cases where CCS functions don't cover my needs, or they are buggy, or simply don't exist. (For example, I need a function that runs the ADC in the dsPIC33, writing continuously with DMA, using all 4 S&Hs.)

Am I correct that the PIC register and bit names, as they appear in the datasheet, are not already declared somewhere? Do I have to create a #byte or #word for every register I want to access directly? For the dsPIC33 ADC alone, there are many registers... this seems like a collosal waste of time.

Since Microchip has all the registers and bits already defined in MPLAB inc files, it would be nice to somehow access them. Has anyone created a batch file or macro or little program to read the Microchip file and spit out a CCS-compatible .h file?

If I'm way off base here, please set me straight. I just need to quickly and easily set registers and bits to configure peripherals, following the step outlined in the datasheets.

Thanks,
Jim

If you have PCW (CCS IDE)you can use the Device editor to do this.

I have the CCS IDE, and will look closer at the device editor. I didn't realize it would be helpful in this case. Can you elaborate just a bit more?

Unfortunately, though, debugging stopped working for me a while ago -- can't get anything to work properly inside CCS. I have the ICD-U40, ICD2, and ICD3. They either don't work or crash my system when trying to debug with them. So I've been working in MPLAB, where both ICDs work perfectly for debugging.

Thanks!

I'm running the most current versions of everything for the dsPIC33. Compiler/IDE version 4.101. Also have the most recent release of Microchip stuff: MPLAB 8.40, and ICD firmware bundled with that release.

Spectacular! Creating an include file of registers and bits is easy. :)

Thank you, ckielstra. Very very very much appreciated!

Thanks for the tips, very helpful.
It's on the register tab and named 'Make include file'
