Hi! I am trying to download the tar.gz python library from github; however when I try to unzip the tar.gz archive via the command line on Raspberry Pi, it returns the following error, suggesting this is not the correct file:
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
Could you please point me to where I can download the correct DLPDLCR2000EVM python library from?
Github link: github.com/.../DLPDLCR2000
Hi Austin, thank you for your reply. I was trying to download the tar file via wget in the command line. I've cloned the entire repository and then unzipped the archive and that worked. However, I now have another issue.
I've followed the instructions in the git readme and installed the DLP library- there's been a lot of syntax errors in the files (I assume there's a difference between python2 and 3?). I've got Python 3.7 installed on my Raspberry Pi. Got through all of the errors preventing me to run the sample scripts, except for one.
I am attempting to run ExtProjOnOff.py, and I get the following error:
Traceback (most recent call last):

ModuleNotFoundError: No module named 'i2c'
Now, I've got the i2c arm protocol enabled in the boot/config.txt file, and I've installed the simbus2 module via pip3 in the command line. I am not quite sure how to get past this error.
Update: if I change line 45 in dpp2607.py from "import i2c" to "import smbus2", it traces back to the following error:
