Procedure for converting code from P232C to PMC232/PMS232

Please follow the below steps for converting code from P232C to PMC232/PMS232:

Go through the PMC232/PMS232 datasheet and user guide;

Modify the source code engineering file “.pre”; change “.chip P232CXXX” to “.chip PMC232” or “.chip PMS232”

Press “Build” and then IDE will show some errors and warnings.

Modify the source code correspondingly until all errors have been solved.

Save and build the project files again.

Write to a real chip and test its functions in detail.

Back to the step 3 if necessary.

Contact our FAE at fae@padauk.com.tw if you still have any problems.
