28757b2 / cc1101-driver Goto Github PK

Hello, I am having an issue that it seems another person has had. However, I utilized the latest download and checked the file to make sure it matched. Do you have any idea of what would be causing this or where to look/troubleshoot?

11.390317] cc1101 spi0.1: Device not found (Partnum: 0x00, Version: 0x00)
11.440640] cc1101 spi0.0: Device not found (Partnum: 0x00, Version: 0x00)

I am using this on a Pi Zero W and using DietPi. I tried Bullseye and Buster previously.

Hello there!

I am trying to use this driver to implement a small proof of concept I wrote to send a captured RF signal. I am using an arduino to send the signal by turning the transmission on and off at specific intervals using asynchronous mode (e.g: '1' for 4000us, '0' for 100us, etc etc).

I am not sure how to translate that functionality here, my best guess is that I have to generate a bytestream that represents the same signal by calculating the bytes depending on the selected baud rate, so for instance if I have to send '1' during 600us and I have a baud rate of 100kbps, In theory I would need to send 10 bits, so that needs to be converted into 2 bytes with padding, correct?

The problem I'm running into is that my captured signal is rather long: it was around 18678 bytes @ 100kbps and it would appear the maximum packet size is 1024. I have some intervals that are 60us so I could reduce the baudrate to about 16kbps but I'm wondering if either my assumptions are wrong or perhaps there is a cleaner way to "stream" data to the radio?

I could fragment the packet into several 1K packets, but I'm afraid the additional processing might introduce delays and botch the signal.

Any ideas?

Thanks!

Hi,

I'm having some problems installing the cc1101-driver, I've followed the procedure but can't get the overlay loaded.
FIrst: When trying to insert the module I get the below message:
pi@raspberrypi:~/cc1101-driver $ sudo insmod cc1101.ko
insmod: ERROR: could not insert module cc1101.ko: Device or resource busy

The insmod command is working after a reboot and can see it loaded with lsmod.

Second:
The cc1101 overlay is not loading. I can't see the expected /dev/cc1101.x.x.
Also the /dev/spidev0.x is also gone.
After removing the /boot/overlays/cc1101.dtbo the spidev0.x appears again and is working fine.
When I try to add the overlay I get the below message:
pi@raspberrypi:~/cc1101-driver $ sudo dtoverlay -v /boot/overlays/cc1101.dtbo

This seems to be the same issue that danucu was having

Neither:
sudo dkms build -m cc1101 -v 1.4.0

nor:
sudo dkms build -m cc1101 -v 1.3.3

work - the make.log that I get for them are:

When sudo dkms build -m cc1101 -v 1.4.0 that give's me error.

Long packets are not sent completely, "tail" is trimmed.

How to reproduce:

1. Try to transmit for example 656 bytes of data
2. Observe debug output, observe transmitted data (it is enough to measure transmission time with some receiver like RTL SDR)

Observed:

• tx underflow in the debug output
• transmission time shorter than expected

Probable root cause:
It seems that packet remainder in tx_multi() is written to TX FIFO too early without making sure that there is a place for it. This causes TX FIFO corruption and transmission cancelation.
