hey,
i m trying to transmit and receive data using two cc1101 chips. i have configured one of them as transmitter while other as a receiver. but i m not being able to access the registers of either the transmitter or the receiver.

the code is attached along with the header files,

can someone guide plx?

If your have provided 5V supply to module then it is damaged. You have to provide 3.3V and if you interface it with microcontroller and micro is 5V type then you need voltage translator. If your arduino is powered with 3.3V then you can interface the module directly.
 

Hoc do you connect two CC1101 chips to a single SPI bus? There must be separate SS lines and also separate GDO0 inputs handled in the code.
 




I have connected it with aurdino and powered aurdino using USB port. cc1101 is connected to the 3.3V pin of aurdino

Click to expand...

I have two aurdinos not 1... so i have conected one with the transmitter and other with the receiver....
 

You are postng the code provided with the Elechouse CC1101 modules. How do you determine that you don't acces the CC1101 registers? Are the modules connected to Arduino as expected by the software?
 

yeah i checked it........ besides there is another issue to begin with

i wrote this command
digitalWrite(SS_PIN,LOW);
delay (1000);
Serial.println (SS_PIN); // i get 10 in ascii

and if i connect led, it glows where as i thnk it shouldn't

and then if i write high to the same pin, it still returns me 10 in ascii

any idea???
 

I'm not familiar with Arduino libraries, but I guess SS_PIN is just a pin number. You are printing the pin number, not reading the pin state.

I also presume, Arduino has more effective debugging methods available, e.g. running code in single step and check it's operation?
 

i m trying to read the value of the configuration register FREQ0

here is the code

#include <ELECHOUSE_CC1101.h>
byte s;
void setup ()
{
Serial.begin (9600);
ELECHOUSE_cc1101.Init();
s= ELECHOUSE_cc1101.SpiReadReg(CC1101_FREQ0);
Serial.println(s);
}
void loop ()
{}




but this returns me 0 everytime........ where as i set its value as 0x62... can some 1 help plxxx?????

}



Where are SPI pin defines? Where is SpiMode() function call?


Did you check this file?
