HDMI-Pi Raspberry Pi to MIPI DSI Adaptor
- johndoe0815 5y agoThis seems to be an external HDMI to MIPI converter based on a custom ASIC (with a link to a different FPGA-based implementation). Since the Raspberry Pi already has a MIPI-DSI interface on board, this seems unnecessary. However, AFAIK the Raspberry MIPI-DSI interface only supports a small number of "official" LC displays and there is no documentation how to configure the interface so other displays can be used. It's time for a really open computer with open documentation and driver code down to the last bit. RISC-V won't help here, since all the peripherals on a typical RISC-V SoC are also proprietary.

Help us take those critical first steps toward a world in which silicon-level trustworthiness is attainable." So RISC-V, but with the cores and peripherals all software defined on an FPGA, so you can audit the code and verify what you upload as "software defined hardware". They've blogged profusely about the design decisions and the philosophies behind them: https://www.bunniestudios.com/blog/?cat=71 https://www.bunniestudios.com/blog/?cat=71
- peterburkimsher 5y agoThe screen resolution of official LCDs is much lower than phone screens. Replacement phone screens are much easier to source than RPi screens. Other non-RPi devices can still be used, e.g. A headless Mac Mini or PC tower, or an HDMI feed for a livestream. This adaptor is amazing to me, much better than carrying a giant flat panel display around!
