Configuring RF1101SE (CC1101) for 433.68 MHZ

TER said:

Download SmartRF Studio and use this to calculate the FREQ word for the frequency you need.

Hello

Thanks for your reply. I have a doubt:

1) I am using the RF1101SE bought from ebay - I understand it has the CC1101 chip, nevertheless.

I downloaded the tool -- but I see a lot of different values -- which ones are the relevant?

I downloaded a lib from the net for this specific device.

the header file from the lib has this registers:

/**
 * RF1101 configuration registers
 */
#define RF1101_IOCFG2            0x00        // GDO2 Output Pin Configuration

#define RF1101_TEST0             0x2E        // Various Test Settings

And the code from the smart RF studio reads the following registers:

#ifndef SMARTRF_CC1101_H
#define SMARTRF_CC1101_H

#define SMARTRF_RADIO_CC1101
#define SMARTRF_SETTING_IOCFG0     0x06

#define SMARTRF_SETTING_FSCTRL1    0x06

#define SMARTRF_SETTING_FREQ1      0xAE
#define SMARTRF_SETTING_FREQ0      0x14
#define SMARTRF_SETTING_MDMCFG4    0xCA
#define SMARTRF_SETTING_MDMCFG3    0xF8
#define SMARTRF_SETTING_MDMCFG2    0x16
#define SMARTRF_SETTING_DEVIATN    0x40
#define SMARTRF_SETTING_MCSM0      0x18
#define SMARTRF_SETTING_FOCCFG     0x16
#define SMARTRF_SETTING_AGCCTRL2   0x43
#define SMARTRF_SETTING_AGCCTRL1   0x49
#define SMARTRF_SETTING_WORCTRL    0xFB
#define SMARTRF_SETTING_FSCAL3     0xE9
#define SMARTRF_SETTING_FSCAL2     0x2A
#define SMARTRF_SETTING_FSCAL1     0x00
#define SMARTRF_SETTING_FSCAL0     0x1F
#define SMARTRF_SETTING_TEST2      0x81
#define SMARTRF_SETTING_TEST1      0x35
#define SMARTRF_SETTING_TEST0      0x09

#endif

Should I leave out all my code from the lib, and just replace it with the new values from the RF studio? or should I just select those relevant registers and update the data of the RF studio code?

I am affraid to fry my CC1101 chip if I write some wrong code.

Thanks for your time to read this.
