UART2 normally uses int rda2

you are right, i miss the ports, C6 and C7 are from UART1, i changed now but still don't work.
| Code: |
#PIN_SELECT U2TX=PIN_C6
#PIN_SELECT U2RX=PIN_C7
#USE RS232(UART1,ERRORS,BAUD=9600,STREAM=WIFI,ERRORS)

I'm surprised the compiler doesn't complain about this.
TX1, and RX1, are not relocatable.
Repeat 50*. "You can _only_ use 'select' statements on peripherals that are relocatable"....
UART1, just needs:
| Code: |
#USE RS232(UART1,ERRORS,BAUD=9600,STREAM=WIFI,ERRORS)
INT_RDA1
//and the code in this must fgetc from 'WIFI'
|
For UART2, you have to select the pins, and the pins used must be RP pins.
Look at table 10-13 in the data sheet, which shows what input devices can be relocated, and 10-14, which shows the relocatable output devices.
It's honestly getting like trying to pull teeth using a pair of tweezers.... |

I will pay more attention to the documentation.
The console display wrong or even connect to uart.
- get mac
Mac Addr=00:06:66:9c:
- $$$
ERR: ?-Cmd
<4.41>
- get ip
IF=UP
DHCP=SERVER
IP2TG
get ip
IF=UP
DHCP=SERVER
IP2TG
- get ssid
SleepTmr=0
WakeTmr=oxb
sometimes the first legend is
&«Kc#Ó&‹VvƦ
otrers:
server init
This is the code. Not always work.

Hello, someone
Several posters on sparkfun report having problems passing data from PICs to the RN-171 device, but no-one mentions the possibility that an inverter is needed between the two to make the communication from PIC to RN-171 work.
The ploblem is that the RN171 dont receive data from the pic or it does with wrong data.
Someone had the same problem?
Thanks |
