LED board cut to size

Forth embedded board via USB serial

Terminals

My normal serial terminal program (ZTerm) doesn’t appear to allow manual control of DTR+RTS (as far as I can tell). I, however, need this control for a ByVac BV511 LPC ARM + Forth board http://www.byvac.com/bv3/index.php?route=product/product&path=20&product_id=49 which uses them to control the reset and program-enable lines. (I first saw the BV511 sold on ebay.co.uk by ByVac).

I tried to install minicom via MacPorts, but for some reason it wouldn’t set up (via sudo minicom -s)

Anyway, found CoolTerm, which allows things like manual RTS & DTR line control and also line delay.

http://freeware.the-meiers.org/ (There is both a Mac and Windows version).

Working with the BV511

CoolTerm was set up to 115200, 8N1.

I also set the end of line delay to a huge number (50) to allow the target to compile when pasting in text.

Copied some I/O code and got the on-board led to toggle that’s on I/O port 0.31 ... very cool (if somewhat simple!)
