you are right, yes .....
Ttelmah !!!
I found the bug. Parity works ok, but it is confused!
Parity=EVEN mean Parity=ODD.
After

Yes, thanks, i do that. I found this :

I can receive 9 bits and send 8bits with same PIC hw uart. There is separate TXSTA.TX9 and RCSTA.RX9 bits.
I just wanted to see how looks C code and learn something. I found some benefits and little ... |

With my minor XP here, i can point what puzzle me in these #use statements.
I had no success to run a hardware spi or uarts on 18F23K22 with them.

I give up. I have not enough brain to understand these #use statements. I guess they are amazing for software communication,
but i can't get working hardware peripheral with them.

I will try, but i really like this style

spi_write2(s);

Ttelmah, i'm sorry:
The definition of the RS232_ERRORS is as follows:
No UART:
· Bit 7 is 9th bit for 9 bit data mode (get and put).
· Bit 6 set to one indicates a put failed in float hi ... |

As a comment though, just put a jumper on JP2 of the display. This turns parity off.

Hi RF,
The device surely uses 9600 8-ODD-1. I solved this task for one LCD to overlay in 2010. I did that with hw uart to receive and software uart to transmit with PIC16F88. And ofcourse, i set r ... |

Hello,
I'm new to " C for microcontrollers ". I read what i found about parity in this forum, but it seems not so clear for me.
I know what is PIC and PIC_UART , but i am puzzled from comp ... |
