The two RS modules in the BIG8051 can operate separately. To connect, switches 1 and 3 (optionally 2 and 4) on DIP switch SW11 should be set to the ON position. -
Page 13: Can Module
BIG 8051 Manual CAN module Controller Area Network (CAN) is a communication standard primarily intended for use in the automotive industry. It is used when microcontrollers and devices need to communicate with each other in applications without a host computer. The modern automobile may have as many as 70 electric control units for various subsystems. -
Page 14: Zigbee Module
BIG 8051 Manual ZigBee module The BIG805 enables you to connect the ZigBee module that is used for wireless communication. The module communicates with the mi- crocontroller with the standard SPI protocols. It is necessary to set switches 1,3 and 5 on the DIP switch SW10, as well as the switches 1,2,3 and 4 on the DIP switch SW15 to the ON position for function- ality. -
Page 15: Mmc/Sd Connector
BIG 8051 Manual MMC/SD connector The development system is able to read memory cards due to the on-board MMC/SD connector. The module uses microcontroller pins for serial com- munication. To connect this module, it is necessary to set switches 1,3 and 5 (optionally 2,4, and 6) on the DIP switch SW10, as well as switches 1 and 2 on the DIP switch SW14 to the ON position. -
Page 16: Comparator
BIG 8051 Manual Comparator The BIG8051 can compare voltage levels due to a comparator built into the microcontroller. Voltage signals are supplied via potentiometers P5 and P6. To enable voltage signals, set switches 5 and 6 on DIP switch SW15 to the... -
Page 17: Adc Module
BIG 8051 Manual ADC module The ADC module is used to convert an analog voltage level into the appropriate 12-bit digital value. The analog voltage signal is supplied via screw terminals CH0, CH1, CH2, and CH3. The ADC module is built-in into the microcontroller. The voltage supplied from the VREF pin is used as a voltage reference. -
Page 18: Dac Module
BIG 8051 Manual DAC module . The DAC module attached to the development system can be used to convert 12-bit digital values into appropriate analog voltage values. The output analog voltage signals is delivered via screw terminals DAC0, and DAC1. Like the ADC module, this module also uses the VREF pin on the microcontroller as a voltage reference. -

BIG 8051 Manual Memory modules The BIG8051 comes with Flash, RAM and EEPROM memory modules. This allows the microcontroller to expand its memory space. The Flash module lets the microcontrol- ler to use an additional 8Mbit flash memory via SPI. To establish connec-... -
Page 20: Leds
BIG 8051 Manual LEDs There are a total of 64 LEDs on the development board and can be used to visually indicate the state of each microcontroller I/O pin. When active, an LED indicates that a logic 1 is present on that particular pin. -
Page 21: Push Buttons
BIG 8051 Manual Push buttons The provided push buttons on the development board can be used to change the logic state of all the microcontroller input pins. Jumper J10 is used to determine the logic state to be supplied on the appropriate microcontroller pin by pressing a push button. -
Page 22: I/O Ports
BIG 8051 Manual Input / Output ports The BIG8051 has 10-pin connectors lined to the microcontroller I/O ports. Due to DIP switches SW1- SW8, every connector pin can be connected to one pull-up/pull-down resistor. It depends on the position of jumpers J1-J8 to control this aspect. -
