Multilevel Programming comes to the G144A12

arrayForth Release 02a includes a fully functional and fully supported high-level polyFORTH® development system for our chips, free of charge. Running on the EVB001 Evaluation Board using a software-defined virtual machine, high level software can now interact with parallel “microcode” sharing the chip’s array of F18 nodes. Like all polyFORTH development systems, this one runs on the target chip and is able to fully reproduce itself from source. Release 02a is accompanied by an updated edition of DB004 (the arrayForth User’s Guide) and a new manual, DB006 (polyFORTH Supplement for the G144A12). All this is available at Customer Support Central as usual.

New App Notes and Courses

Two new App Notes have been posted: AN001 is a revision of an MD5 example, and AN008 by Peter Milford describes a high-level interactive process of testing a 3-axis accelerometer, verifying its protocol documentation, and obtaining data from the device. Download them from the Index of Downloads. In addition, the arrayForth Institute offers two new courses. “Application Notes” is structured to present one application note in each learning path. The first such App Note is AN008. Register for the course to view Peter’s video presentation of the project in question. An additional new course, “The Commons”, provides an experimental venue for interaction among those interested in GreenArrays technology.

arrayForth® Institute has opened!

GreenArrays is pleased to announce the opening of the arrayForth Institute, a free online learning resource intended to faciliate the successful use of our chips. Access via https is supported for those who prefer encrypted communications and don’t mind the possible inconveniences. The curriculum is organized in courses, each of which is subdivided into one or more Learning Paths. The first such path is in place and ready for use. Anyone interested in our products may create an account and take our courses. Feedback will be appreciated!

At the same time we are improving the organization of the GreenArrays Website during March to make it easier to keep abreast of our literature.

Best wishes to all!
