| 24FJ..Buffered RS232 still not working - any help please |
 Posted: Tue Aug 21, 2012 4:23 pm |

Hi,
I have started to write a simple program for buffered RS232 communication on the 24FJ64GB106. The non buffered procedure is working well, however the buffered routines are not working. Could you please make a short lookup and suggest me where I'm wrong. Thank you in advance,
Best Regards

The obvious big mistake, is you are talking to the wrong function.
_putc_ (and bputc for the buffer), is the function to 'put' data. You are printing to 'bgetc', the function to get data.....

Hi Ttelmah,
Thank you so much for your indication. I corrected it as alo other small mistakes I have found. However it is still not working. I have used it 100 times in the 8 bit processors, but it is my first impression with 16bit. May be you can see it again, please, ansd have any idea. 4 eyes is much more than 2 eyes :-)
My best regards
here is the corrected code with your and some mine corrections
