4 in this quick start guide, you will learn how to set up the TWR-PXR40 module and run the included demonstration software. for more detailed information, please see the user manual found on the included dvd or at freescale.com/TWR-PXR40 . quick start guide connecting the twr-ser insert the TWR-PXR40 and twr-ser boards into the primary and secondary elevator board. the primary and secondary cards for each module are indicated along the card edges. powering up the TWR-PXR40 connect the TWR-PXR40 board to a computer or a wall charger using the provided usb cable. additionally, the usb connector on the primary elevator or osjtag connector can be used to power up the board. using the serial to usb bridge the mc9s08jm60 serial to usb bridge solution provides an rs-232 equivalent connection to the host computer through the usb communications device class. when plugged in and powered, the usb connection will enumerate as a com port on the pc. to determine the com port number for the connection, right click on the my computer icon and select manage, click device manager, find and expand ports (com and lpt). installing the software driver when the cable is plugged in for the first time, then found new hardware wizard will start. select the option install from a step-by-step installation instructions 1 3 4 2 note: for windows xp 64 bit users please connect db9 connector to the twr-ser card.
5 tower system list or specific location (advanced), then select next. select the cdc virtual serial port folder which is available on the dvd or at freescale.com/TWR-PXR40 . the wizard will find the updated driver within the folder and install it. installing and using freemaster install freemaster (fmastersw. exe) which is available on the dvd or at freescale.com/freemaster . open the freemaster file demo-TWR-PXR40. pmp. go to the menu project and select options, set the communication to use the com port from step 4 and the speed to 115200. running demonstration code press the reset button on the board, on freemaster deselect the stop button, and select demo scope, the chart will appear showing the accelerometer values, move the board to see the values changing. rotate the potentiometer to see the value on the watch-grid. press the buttons to see the status on the watch-grid. change the value of the ledx to 1 to turn it on. 6 5 ? mqx? real-time os ? ashware etpu simulator ? bytecraft code development system for etpu ? green hills software multi ide ? serial bootloader utility ? codewarrior v10.x eclipse development studio ? osjtag virtual serial port using usb ? rapid application initialization and documentation tool (rappid) ? freemaster runtime debugging tool additional software and tools
