#USE RS232 -> ERRORS

[12Lapointep]

Hey all,

After reading in the CCS C Compiler manual updated in May 2015, I still do not clearly understand what ERRORS mean for the #USE RS232 preprocessor directives. I have used it in my previous codes but it does not seem to change anything flow or content.

ERRORS: "Used to cause the compiler to keep receive errors in the variable RS232_ERRORS and to reset errors when they occur."

Anyone have a better definition for this?

Thank you!

They mean UART framing errors and hardware buffer overrun errors.

When you operate a uart you can encounter the errors mentioned by pcm. Normally this makes your uart dead in the water until you clear them. The ERRORS keyword does this for you when read the uart buffer. It also provides a variable you can optionally check to see which errors occurred. It is considered a "required" option for the uart for most users

Thank you all for the comments. It is very clear now.
