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.
The GGLABS T232 is very popular for debugging legacy RS-232 connections. In this article we will describe a few debugging tips and show how to emulate some of the common cable configurations.
RS232 monitors are quite common but most of them use the standard good old DB25 connectors. The majority of the RS232 ports in use today however use the smaller DB9 connector. This forces the use chains of adapters to get the commercial monitor/breakout boards working. The GGLABS T232 solves the problem by providing native DB9 connections.

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.
A new release of SDCC, the portable optimizing compiler for 8051, DS390, Z80, Z180, Rabbit 2000, HC08, STM8 and PIC microprocessors is now available. Sources, documentation and binaries compiled for x86 Linux, x86 and x64 MS Windows and x86 and PPC Mac OS X are available.
Many MCU applications use electro-mechanical relays to control AC loads. While this is an excellent solution for occasionally turning on/off a load it is not suited for frequent switching or PWM applications. SSR01 is an opto-coupled solid state relay that can control two AC loads up to 16A each.
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.
The SDCC team is spoiling us with yet another great release. After a little less than one year of development and 3 release candidates the new 3.3.0 version is ready for download.
Besides the numerous bug fixes here is a list of the important changes since the release 3.2.0 (list taken from SDCC website):
