GPIO SLICE CARD

The is a GPIO slice card for use with slicekit. This GPIO slice card provides a collection of features to slicekit including LEDs, buttons and A to D inputs. Combined with xSOFTip it allows simple input/output functions to be evaluated easily and provides I/O expansion to connect sliceKIT to other systems. A pair of 1bit ports 1 each for RX and TX are used with an RS232 transceiver and DB9 connector to provide a standard UART terminal running up to 115.2KBaud which can be connected to any PC COM port or serial to USB adapter. An ADC with a standard two wire interface is provided, with an external linearised thermistor connected to the first ADC channel. The remaining three ADC channels are exposed on testpoints.
