Testing the serial port in Bolt 18F2550 system
We provide a test program that allows communication and remote control between a PC and the electronic Bolt module, using a serial cable, at 9600 bps. In the C18 compiler project, you must include also the standard library for the serial port <usart.h>.
Testing may be done using a Laptop computer with a USB-Serial interface and an external wall transformer to power Bolt 18F2550 system, as shown in the photo (jumper JP1 must be placed in external power supply mode).
Use a terminal emulator software -as Hyperterminal- to do your testing. Configuration is 9600,n,8,1
Load from the table below the test program (.hex file) in Bolt 18F2550 and try the commands listed in the table below.
