Silicon Labs makes many excellent 8051 based MCUs. All the MCUs in the EFM8UB line have a native USB and are pre-programmed with a USB HID bootloader. EFM8 Flash is a small GUI tool to flash the MCU from a binary file. The program uses the wxwidgets toolkit for a native look in all supported operating systems and hidapi for cross platform compatibility.
Real Atari 2600 Joysticks are necessary for a truly authentic feel when using an emulator. The UJOY interface allows to connect one Atari Joystick to a standard USB port.
ProtoJS is small (5x5cm) board with a minimal S08JS implementation and a standard 100mil prototyping area. While similar in features to our microJS, protoJS is more suited to permanently wire simple one off USB projects.
gboot is a very simple USB HID bootloader for Silicon Laboratories USB microcontrollers. It has been developed for C8051F32x and C8051F34x but it should work on the F38x as well.
We are proud to announce that gglabs was chosen by the LCD Smartie team to design a custom USB interface for text displays specifically designed for LCD Smartie. The result of our collaboration is the LCD Smartie official hardware. Beside purchasing the most advanced USB based LCD interface on the market, your money will serve good cause as part of the profits will go to the LCD smartie developers.
