SEROUT and HSEROUT

I'm working with 18F6720 and RN171 (WiFly). I need send commands to RN171 with Uart.

Then I send

serout PORTC.6,N9600,["$$$"]

and RN171 don't reply

but if i send

DEFINE HSER_BAUD 9600
hserout ["$$$"]

then RN171 reply CMD (OK).

Where is the problem?? SEROUT and HSEROUT don't work equally??


best regards

Try mode T9600 for serout.

with T9600 is the same

It's likely in the configuration bits.
Post your complete code.

Try SEROUT2

Is USART also using port c? (haven't checked datasheet from phone).

Analog on port c?

Configs ok?

The short answer is No, UART is the HARDWARE serial port whereas serout & serout2 are bit banged serial routines. The hardware UART will receive or send data only on the Rx & Tx pins of the PIC. The bitbang serial ports will operate on nearly any port or pin. Debug is also a bitbang serial port and many will say the neatest and fastest of the bitbang routines. The UART will send & receive 2 bytes while code is doing something else. Not so with bitbang.
