The LOGI Pi is an FPGA development platform that has been optimized for use with the Raspberry Pi. The LOGI Pi/Raspberry Pi combination was designed with key design attributes in mind including ease of use, maximum expansion capability and low cost to performance ratio. The LOGI Pi creates a powerful and versatile digital canvas for users to create their imaginative digital designs.
The LOGI Team has developed software and drivers that make it easy for users to communicate between the FPGA and the Raspberry Pi. APIs and Wrappers have been written that allow easy access to the FPGA custom hardware peripherals using the wishbone bus standard. Applications can easily be written using C,C++ in conjunction or with python. APIs for these languages allow easy to use communication with the FPGA.
The LOGI Team has created a number of applications for the LOGi-Pi including a bitcoin miner, machine vision and autonomous vehicle and robotic controllers. All applications are open source and available on the LOGI repository. An “App Store” (Free) application methodology has been developed that allows users to simply download the latest fully built applications and run them with no need to delve into building the HDL and source code.
The LOGI Team is developing custom hardware modules to enable direct support for applications that they could not find an easy existing solution. LOGI Hardware modules are designed using the widely used standards including Digilent Inc PMOD, Arduino Shield and high bandwidth modules using SATA connectors (For LVDS expansion only - SATA protocol not supported). Existing LOGi modules include the LOGI Cam and the LOGI EDU.
