I have now ported my Arduino library for controlling Sharp Memory LCDs to the Raspberry Pi. The extra memory and processing power available on the Pi certainly expand what you can do with this great little display. The lowly Arduino and even the 80 MHz ChipKIT did struggle to complicated process frames of data for […]
Ever wondered where utilities like top, jnettop, free and mpstat get their information on CPU usage, network throughput, free RAM etc. from? Well, the majority of it is hidden within the /proc filesystem, most of the rest can be found in /sys and the last few scraps have to be gleaned from elsewhere. Some of […]
This weekend I ported my Arduino library for the Sharp Memory LCD breakout boards I’m selling to the Raspberry Pi. At the moment, I have the short demo running successfully although the code does need (and will be receiving) further improvement. However, it’s already great to see how smooth the demo runs on it, with […]
If you’re wanting to use a Memory LCD with an Arduino, there are at least four software libraries to choose from. In no particular order, they are: The Rengineer’s Memory LCD library: https://github.com/TheRengineer/MemoryLcd Supports drawing basic shapes and printing bit map images. You may have to replace instances of ‘prog_uchar’ in the code with byte […]
While browsing the Raspberry Pi forums the other day, I came across a thread called “Potentially useful things to program” which reminded me of a problem I solved when I was first becoming interested in programming. The code I wrote to solve the problem wasn’t a particularly useful thing to program, as in the Raspberry […]
