16F88 7 data bits

I thought the DEFINE for SERIN/SEROUT stuck constant for the whole program...like you can't re-DEFINE it.

They do - that is why I suggested using SEROUT for one and SEROUT2 for the other. They are not related by the defines

AHA! Missed that!

In the software serial routines, MELabs must be looking at the settings in order to determine how to send the data bits and set the parity right? Problem is it's a define and not a variable or it most likely could be changed on the fly.

I sure hate to bit bang this but I may have to.

>>I sure hate to bit bang this but I may have to.

you do not have to, PBP has done the work for you.

>>two adjacent pins connected together

another thought - no need for adjacent pins - use SEROUT for 8N1 and SEROUT2 for 7N1 ... using the same output port pin.

If PORTA.1 = 1 then ; check jumper
SEROUT PORTB.0, .... ; need 8N1
else
SEROUT2 PORTB.0, ... ; need 7N1
ENDIF

will that work?

Also, I do not see why you keep mentioning CCS??? We are taking PBP here

I'll give it a shot this morning. It "should" work.

Why do I keep mentioning CCS? I only mentioned it once in an effort to show it is possible to do it But upon closer examination, it also only handles it in software only.

Hi Richard,

I hope this approach works for you.

Hi Richard,
I this approach works for you.
Best of the Day,

I ended up using SER2 for the 7,N,1 Stuff then
using HSER for the 8,N,1 Stuff.

Check the Dip switch, Configure TXSTA, RCSTA, SPBRG to the values needed or Zero if not needed. This worked great and allowed me to still use the modifiers like in SER2.

Thanks for the ideas.

Richard
