SERIN2 = ok, HSERIN = no!

EDIT: Your baud looks good.

At first I didn't see your BRG16 =1, but Steves Picmulticalc is still good. I'll see if I can find anything real

Steves PicMultiCalc tool works great for this, and give you text results you can just paste in to your code. Just enter OSC speed, baudrate, and press the go button.

DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 20h ' Enable transmit, BRGH = 0
DEFINE HSER_SPBRG 12 ' 9600 Baud @ 8MHz, 0.16%
DEFINE HSER_CLROERR 1 ' Clear overflow automatically

... I used PICMulticalc and pasted its results in my first post's HSERIN code; unfortunately it doesn't work.

Could it be hardware related? Pull-up or current-limitting resistors?

What about the Mode setting (True VS Inverted)?

EDIT: You use Open,True,N,9600bps for SERIN, that's inverted.

You use BAUDCON = %01001000 for HSERIN, bit 5, 0 = non-inverted Data/Receive Polarity.


There could be other stuff, but that's all I got.

Hi Demon,

I tried all that already. Neither a new chip nor data polarity will change anything; HSERIN won't work...while SERIN2 does :-/

BAUDCON bit 3

BRG16: 16-Bit Baud Rate Register Enable bit
1 = 16-bit Baud Rate Generator – SPBRGH and SPBRG
0 = 8-bit Baud Rate Generator – SPBRG only (Compatible mode), SPBRGH value ignored

Don't you want 8-bit?

I tried BAUDCON = %10000000 if this is what you mean. No luck either.
