IPS-PI40 is a 480x320 4.0" IPS display connected to RPi's SPI bus. It works with 64 MHz SPI clock and is capable of approx. 17 FPS. Additionally it compresses the data that is being transfered over SPI. SPI compression works very well in GUIs therefore FPS in GUIs is much higher. Comes with a resistive touchscreen and controller. Optionally five push buttons can be mounted.
The IPS-PI40 connects directly to the GPIO connector of the RPi. IPS-PI40 uses only SPI pins and one GPIO pin. Optionally additional pin can be used for backlight dimming. The rest of pins are free for other use. Push buttons require no additional GPIO pins, their status can be read over SPI. The shield also includes 4 mounting holes for
The IPS-PI40's driver makes it a primary display for RPi which means that there is no need for any special libraries easy mounting.or software to control the LCD. Common software like Qt, Xwindows, etc. can be used for developing applications. Driver and display support DMA, SPI compression technology and up to 64 MHz SPI clock.
Raspbian based images with compiled drivers are available under Documentation link. Please check Source code link for compiling custom kernels.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
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.
