User GPIO Signals (J2)

The ReadyBoard 700 provides eight GPIO pins for custom use and the signals are routed to connector J2. There is an example of how to use the GPIO pins in the Miscellaneous Source Code Examples subdirectory, under the ReadyBoard 700 Software menu on the ReadyBoard 700 Doc & SW CD-ROM, (RB700\software\examples\GPIO)

The example program can be built by using the make.bat file. This produces a 16-bit DOS executable application, gpio.exe, which can be run on the ReadyBoard 700 to demonstrate the use of GPIO pins. For more information about the GPIO pin operation, refer to the Programming Manual for the Secondary I/O (W83877TF) controller at:

Notes: The shaded area denotes power or ground.

Temperature Monitoring

The Southbridge (VIA VT82C686B) chip performs the temperature monitoring function and has inputs directly from two thermistors on the board. One thermistor is located near the CPU and the other thermistor is located near the Southbridge.

NOTE	The ReadyBoard 700 requires a heatsink for all Intel processors
	(Celeron, Pentium III) and the Northbridges, but no fan.

Serial Console

The ReadyBoard 700 supports the serial console (or console redirection) feature. This I/O function is provided by an ANSI-compatible serial terminal, or the equivalent terminal emulation software running on another system. This can be very useful when setting up the BIOS on a production line for systems that are not connected to a keyboard and display.
