You are Go for FPGA!

Reconfigure.io is accepting beta applications for its environment to configure FPGAs using Go. Yes, Go is a programming language, but the software converts code into FPGA constructs, so you don’t need Verilog or VHDL. Since Go supports concurrent routines and channels for synchronization and communications, the parallel nature of the FPGA should fit well.

According to the project’s website, the tool also allows you to reconfigure the FPGA on the fly using a cloud-based build and deploy system. There isn’t much detail yet, unless you get accepted for the alpha. They claim they’ll give priority to the most interesting use cases, so pitching your blinking LED project probably isn’t going to cut it. There is a bit more detail, however, on their GitHub site.

Running Golang on the Intel Edison

While most embedded development is still done in C and/or assembly, some people are working with more modern languages. The team over at Gobot has successfully managed to get Go running on the Intel Edison.

The Go programming language, which has been around for about five years, compiles to machine code like C. It has a number of modern features including concurrency, garbage collection, and packages.

We’ve looked at the Edison on Hackaday before, and even took a detailed look at the hardware. It features a Quark SoC, Bluetooth, and WiFi, which makes it well suited for connected devices.

Getting Go to work on the Edison hardware wasn’t particularly difficult, since it supports the Pentium instruction set and MMX. However, a library was needed to interface with the Edison’s peripherals. The Gobot team whipped up gobot-intel-iot, which makes it easy to work with GPIO, I2C, and PWM.

After the break, the team demos PWM on the Edison using Go.
