Recently I have been using an \u00a0mbed<\/a>\u00a0micro-controllers. These are a great way to rapidly prototype micro-controller projects. \u00a0One of the great features of the boards is that they provide a serial-over-usb port that can be used to communicate with the board.<\/p>\n

The boards have a good range of on-board peripherals (a:d d:a,pwm,rtc, counters), and can read\/write to usb, connect to ethernet.<\/p>\n

One of the problems I encounter when moving to new dev tools and\u00a0micro-controllers\u00a0is the lack of\u00a0on-board\u00a0debugging. An alternative can be to hook something up to a serial port so that you can “talk” to your board, read values from variables and ports.<\/p>\n

When working on a new project I like to have the command shell available on the device as well as the program I am working on.<\/p>\n

http:\/\/mbed.org\/users\/jont\/code\/JonsDebugTerminal\/<\/a> uses the serial over usb port and provides a very simple command “shell”. It can be extended to support the functions you need. As it is, it allows setting of the real time clock,\u00a0interrogation\u00a0the A:D\u00a0converters\u00a0and the control a few port lines on.<\/p>\n

The code is not robust, or neat, or K&R, \ud83d\ude42 the code has a *lot* of scope for improvement. Its old code I wrote in the 90’s for another micro.<\/p>\n

But its good enough to allow you to play with the board and can be help when developing a new project.<\/p>\n","protected":false},"excerpt":{"rendered":"
