Bus Pirate Linux I2C bus driver

buspirate's Issues

Unable to get BusPirate to show up as i2c bus

Hi Tony,

If built your module as per your instructions except for 2 small variations ;

• in include/linux/tty.h 25 was already used (kernel 4.9.0.9) so I used 26 instead
• in sys-utils/ldattach.c I also used 26

Everything compiles normally and I am able to load the module without any issues.
I can confirm that the buspirate is connected properly and working. I can manually set it to i2c mode via picocom and run a scan for addresses successfully.

If I run "ldattach BUSPIRATE /dev/ttyUSB0" everything seems to work correctly.
Howevever, if i then run "i2cdetect -l" , I get no output.

If I run "ldattach -d BUSPIRATE /dev/ttyUSB0" I get the following :

root@slam:~# ldattach -d BUSPIRATE /dev/ttyUSB0
ldattach: opened /dev/ttyUSB0
ldattach: set to raw 0 ---: cflag=0xb0
ldattach: line discipline set to 26

which seems correct.
But I still get no output out of "i2cdetect -l"

I was wondering : do I have to recompile my kernel with the changes to include/linux/tty.h (I dont think so... but I just want to make sure).
If that isnt the case, would you have any pointers as to what I might be doing wrong ? Is there anything I can do to troubleshoot this further ?

Thanks in advance
