This program is a initial connection test of mBed and Texas Instruments EZ430 Chronos Watch. The Chronos RF Access Point radio dongle is connected to mBed usb port , and it's configured as a usb host. The program uses the USBHostSerial library.
Chronos Test
- This program is a successful connection test between mBed and the watch EZ430 Chronos Development Tool from texas Instruments.
- The RF Access Point usb dongle, that comes with the watch, emulates a usb serial port when connected to a PC. I connected it to the mBed usb port , configured as host ( two 10 K ohms resistors from D+,D- to gnd , I know the recommended value is 15k ) and based the development on the USBHostSerial HelloWorld example program.
- The mBed leds are activated based on the button received from the watch : led2 goes on when the "*" button is pressed , led3 when the "#" button is pressed and led4 when the "up"button is pressed .
- In order to function , you have to select the "ppt control" mode on the chronos watch and after that , start the transmission pressing the "down" button on the watch.
