HwLevel is a team of people that work or used to work at the Faculty of Computer and Information Science, University of Ljubljana. We have developed or have been a part of development team for commercial products and products used in scientific experiments, for example data acquisition and monitoring unit for deployment in underground mines, ARM9 based system used in teaching process, programmable ultrasonic sensing system for targeted spraying in orchards, RTK DGPS module for targeted spraying, etc. We usually develop both hardware and firmware. In digital signal processing we specialize in digital filters, spectral analysis and speech recognition.
We have designed our first 3.2" SPI LCD module since we needed it for a product we were developing. It proved to be a interesting as a development module so we improved it and designed some other models. Although we advertise our displays as displays for the Raspberry Pi, they can be used with any embedded system with SPI bus. They are based on our controller that enables us to high speed SPI transfers (up to 64MHz SPI clock on Raspberry Pi) and larger LCD panels with up to 800x480 resolution. We also provide a Linux framebuffer drivers that make LCD-PI displays to be primary displays. This means that they show the same picture as we see on monitors of Linux workstations. Therefore standard development tools like Qt, X windows, etc. can be used for application development and there is virtually nothing new to learn if one wants to start using our displays.
