33EP512GP806 and fprintf (FIXED)
PostPosted: Mon Jan 08, 2018 11:48 am     Reply with quote

Hello.

I try to put some data to serial port but i can only see "0x00" on windows terminal. Is there problem processor fuses or serial port init?
Thank you for your help.

PIC: 33EP512GP806
Compiler: CCSC PCWHD 5.074
Computer: win7 ultimate x64

Processor FUSES:
Code:
#fuses HS, NOWDT, PR, WPOSTS16, NOCKSNOFSM
#use delay(CRYSTAL=10MHz)


Serialport init:
Code:
#pin_select U1TX=pin_d7
#pin_select U1RX=pin_d6
#USE RS232(stream=UART1, ERRORS, BAUD=115200, STREAM=HW_CONSOLE)


Main:
Code:
fprintf(HW_CONSOLE, "\n\rTesting\n\r");
delay_ms(500);

While I don't use that PIC, this line..
#USE RS232(stream=UART1, ERRORS, BAUD=115200, STREAM=HW_CONSOLE)

may not be legal....

others may know for sure.

Get rid of the "stream=" and it will probably work.

I'm not noticed that dual stream name at all! Fixed lines is now:

Now setup is:
Code:

#pin_select U1TX=pin_d7
#pin_select U1RX=pin_d6
#USE RS232(stream=UART1, ERRORS, BAUD=115200)


fprintf:
Code:
fprintf(UART1,"Testing..\n\r");


Still one "0x00" mark is coming terminal..

It is cheap chinese usb to rs232 module. I think driver is something like CH3xxx. This problem is very strange because it always put that one 0x00 and that's it. Even it there is text "testing.."

Fixed!!


I made a new circuit board an different rs232, still same.
I changed a different USB- converter, still same.

code change

this:
Code:

#USE RS232(ERRORS, BAUD=115200, STREAM=HW_CONSOLE)


to this:
Code:

#use rs232(UART1, baud=115200, ERRORS, stream=HW_CONSOLE)


Maybe I was too tired and did not look at my code exactly enough Embarassed
