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.
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.
