RF Modules

[tonyfelloni]

Is this what it looks like?

That's the one alright!

Thanks for all the input.
I have managed to get these working, they will only work when the baud rate is set to 19200 and the DEFINE HSER_TXSTA must be set to 24h when working off a 4Mhz Crystal.

Thanks

Hello tonyfelloni

I look for a similar wireless solution. What you say about this moduls? Work´s good? It's hard to use it? Have you a sample code that works that you can share?

Thanks
Best regards

Hi Pedro

The modules I used were cheap as chips and I have found them quite reliable...I would reccommend them all the way, the instructions are crap but the comments above are completely accurate and will iron out any issues you may have. You need to use a PIC that has a hardware USART such as 16F88 as the RF modules only run at a baud of 19,200 and with picbasic only the Harware USART can achieve this.

Apart from that if you can't follow the instructions written by some asian dude in a language fit for a 12 year old get back here and ill try help you out with any problems u may have.

Luciano's analysis of the modules is 100% by the way.

Hi tonyfelloni

I will get 2 pieces to test it and if i have problems to run it i ask for your help

Thank You

FYI. DEBUG can send serial data at 19200 with a 4MHz oscillator, and you can use most any I/O-pin.

@ DEVICE PIC16F627A, WDT_OFF, MCLR_OFF, LVP_OFF

DEFINE OSC 4
DEFINE DEBUG_REG PORTB
DEFINE DEBUG_BIT 2
DEFINE DEBUG_BAUD 19200 '38400
DEFINE DEBUG_MODE 0 ' 1 = inverted, 0 = true

Main:
    DEBUG "Testing 19200 bps @ 4MHz",13,10
    PAUSE 1000
    GOTO Main

Hello Bruce

tonyfelloni said that it must use the hardwareUart from the pic. I not understand why.
Perhaps a buffer problem why it not function with SoftUart?
The modul hande up to 64 bytes, is this why must use the hardwareUart

You need to use a PIC that has a hardware USART such as 16F88 as the RF modules only run at a baud of 19,200 and with picbasic only the Harware USART can achieve this.

My guess would be he didn't know DEBUG would work at 19200.
