RF Modules

[tonyfelloni]

Hey cheers for the reply.

Sorry for not posting the data sheet. I thought it was more of a general question assuming most RF module opperate in a semi similier manner. As for the make and model, there pretty much a no name device, I bought them off ebay, model Cy2198TR-a. Have attached the data sheet that came with them.

Best Regards

That datasheet pretty much blows IMO. Looks to me like a car owners manual...doesn't tell you how to overhaul the engine, just what the car is supposed to do.
Any other data around for this module?

That would be to easy. Some transmit the data as it is received no matter what the baud with out configuring (up to a point) and others can/need be configured.

The data sheet you have does not help.
Maybe Dave Houston will see this thread, he has a loot of experience with RF and maybe he has seen this one before.

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

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

Best regards

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
