While trying to use daqhats inside of a Docker container I receive the error 'Error: module 'daqhats has no attribute 'mcc118''. This occurs on a Raspberry Pi 3B+.
I have added support for C type TCs. I think that it can be useful to other users that need a high temperature TC.
MCC128 on RPi5: Fluctuation in number of samples returned by a_in_scan_start() and a_in_scan_read()
I am running a continuous voltage acquisition on the MCC128 on a Raspberry Pi5 (with a `PREEMPT_RT`). I am running the DAQ card with 10 000 samples/second rate and reading...
The file descriptor was left open after the function returns.
The existing Python bindings look fairly straight-forward to port, and build crates like [`cc`](https://crates.io/crates/cc), [`bindgen`](https://crates.io/crates/bindgen), etc. make FFI pretty trivial. Thoughts / interest?
If you don't follow the instructions and only install the Python library, without installing the other software, you can do the following: ```python >>> from daqhats import hat_list >>> hat_list()...

…uous scan - Increased buffer size from 1000 to 50000 samples per channel - Reduced usleep from 500ms to 100ms for faster data reading
The script defines SYS=/sys/class/i2c-adapter/i2c-$BUS which doesn't exist on my pi3B (Linux version 6.12.22-v8+) Because of that a second board will fail to be detected. (I'm using an MCC128 and MCC118)...
