This week I was working on the device driver for the camera. The plan is to interface with the camera through v4l2 (video for linux 2) which comes preinstalled on the raspberry pi and is supported by the raspberry pi HQ camera. We managed to capture some raw images from the camera but realized that without a lens, they don’t look very good. So I ordered a camera lens. I also worked on improving the LCD screen device driver to make it print out special characters for the suits.
Since I wasn’t able to finish the camera driver, I am a bit behind schedule, but once the lens arrives, I expect finishing the driver to be fairly straightforward.
Next week, I’ll finish up the camera and work on writing the receipt printer device driver. Hopefully in the process of formalizing the driver I will be able to figure out exactly what the confusion with respect to the bitmap printing commands was.
