The BLC876A consists of the SBC28PC-IR2 fully assembled Single Board Computer with a 20MHz crystal and a PIC16F876A microcontroller. The PIC is programmed with the free bootloader from Microchip. No special programming hardware is required to get your code working this board. All you'll need is a 9-pin serial port on your PC and a CAB3S6FT 3-to-9-pin serial cable. - Connect the board to your computer via a CAB3S6FT serial cable (sold separately).
- Download the zipped Bootloader PC software and unzip it to a folder on your computer.
- Start the PICbootPlus.exe program, and set for 56000 Baud and correct COM port.
- Load the target hex file you want to program the PIC with (click Search button).
- Click on the Write button and apply power to the board. The PIC will be programmed with the given hex file.
- After resetting the board, the new program will be executed.
Note: The CAB3S6FT serial port cable is not included in this package, but is required to use the bootloader unless you make your own cable. This six-foot cable has a 9-pin Sub-D female connector on one side and a 3-pin Molex plug on the other. The cable connects to the 3-pin Molex connector on this PIC board. You may add the cable to your order using the option box below. PIC16F876A Bootloader Board Features - 14.3 kBytes of Flash program memory
- 368 Bytes of SRAM
- 256 Bytes of EEPROM
- 5 MIPS instruction cycle -- 20MHz crystal
- 22 free I/O pins
- 5 Analog inputs with 10-bit accuracy
- 2 Analog comparators
- 2 PWM (CCP) modules
- SPI and I2C bus
- Two 8-bit timers and one 16-bit timer
- Brown Out Detection circuitry
- Watchdog timer
- Low-power modes
- CPU has built-in circuitry for in-circuit debugging
- 3-pin single line Molex connector with RS232 TX, RS232 RX and GND pins. The CAB3S6FT serial cable connects to this.
- Socket for optional CAN transceiver (such as Microchip MCP2551-I/P).
- Operating voltage from 7V to 30V
- 2.1mm power connector for standard DC transformer
- 6-pin Micro-MaTch socket with Power, I2C and SPI signals
- Power LED
- Compact Daughter Board connector and pads for a Frontend connector to add expansion capability. (Frontend connectors are not installed.)
- 5-pin 3.81mm terminal block (Phoenix) with RS232 (when CAN interface chip is removed) or CAN BUS signals, ground and external power. Matching screw terminal connector included. Spare connectors are available.
- The power pin on the 5-pin terminal block connector can be connected to the board's unregulated power supply (the input of the 2.1mm power connector) via a strap. This can be used to:
- Provide power for all other boards daisy chained to this one. For this to work this board must be powered via its 2.1mm power connector.
- Obtain power for this board. In this case no power has to be supplied via the 2.1mm power connector.
The Micro-MaTch connector allows you to use this board to drive one of the LCD2S- Serial LCD displays found in our LCD Displays category. Multiple I2C devices can be daisy-chained together using the Micro-MaTch connector. Build an Enclosed System Using the Compact Daughterboard connector, this RS232 and CAN board can be used as a control module for the Input-Output-Relay Board, which comes in a sturdy enclosure. You also can make a fully enclosed system by connecting this board to the Add-on Prototyping Board with 10 I/O Ports or the Add-on Prototyping Board with 24 I/O Ports, each of which also comes in an enclosure. Optional In-Circuit Serial Programming Adapters PIC ICSP Board Connector to DIL Adapter Set, In-Circuit Programming Adapter Set for connecting this PIC board's ICSP connector to out-of-circuit PIC chip programmers with a DIP/ZIF socket. PIC ICSP Adapter, 6-pin Single Row to RJ12 and 2mm 2x4 Header, In-Circuit Programming Adapter for connecting this PIC board's ICSP connector to the debuggers programmers with RJ12 jack or single row square post headers. Optional Daughterboards and In-Circuit Debugging Connections This board features connectors for either attaching a daughterboard, or using this board as a daughterboard on a larger add-on board. It also features a 2x4-pin in-circuit programming header. For details on these options, see the description of the SBC28PC-IR2 board on which this product is based.
