Registers are 0 at debug mode

[ahmetaki]

Hello, I wanna ask some question about module and debug lib. I use debug library as you say and results are "0". I check my connections and my module is working properly 2 days ago.

Are my module burned? Are there anything to i do?

I have 5 module, and all of them like that. 2 of them are brand new. one this result are "1F".

thanks for the help

Hi there,
if the rigister 0 are mostly wrong with the spi connection. It is important that you use 3.3v for the power supply of the cc1101. in order to draw conclusions about the problem i need to know which microcontroller you are using and what your sketch looks like. the 1f on each register appears to show that the spi connection is ok but the cc1101 is not yet initialised.

Regards

thanks for reply, I use Arduino uno (atmega328P) and CC1101 D-SUN module. My connections for uno:
3.3v ->3.3v
SCK->13
MISO->12
MOSI->11
CSN->10
GND->GND
GDO0->6
GDO2->7

i realize sometimes sketch is doesnt start until i disconnect any cc1101 pin.

thanks for the help, stay healthy 👍

that the sketch only starts when you interrupt a pin is not normal. with the dsun module and the uno, I am not aware of any problems in this regard. which arduino ide version are you using? with what have you wired (breadboard)?

Arduino IDE 1.8.13 I am uploading a video about sketch start problem.
