What other things will I need to buy or get if I order an HCS_C board?

You'll need cables. You'll get a loaded HCS_C board, a loaded Adapter board that

plugs into the HCS_C ARM JTAG connector. You'll receive a short RS232 cable that

plugs into the console 8 pin molex RS232 connector. You'll receive a power cable that can

be connected to a current limited lab supply. You'll receive an FPGA Config Eprom

programming cable (if you order the JTAG adapter). All other cables, you will have

to supply.

What add-on or expansion boards are available?

Dec 3, 2006 The HCS_C Combo card is now available. This powerful remote board has a long list of capabilities, including four channel analog input and outputs, four optoisolator inputs, three relays, a voice recorder chip, video output capability, PS2 keyboard support, and a 16 channel programmable IO port. Other expansion cards can be plugged into this IO port. In addition, the 16 channel light duty and heavy duty relay boards are available.

These cards are undergoing test

c: 16 optoisolated inputs. The inputs are completely independent of each other, you supply about 10mA of current into the opto LED. Since there is no shared ground with HCS_C, this provides maximum independence and isolation from the HCS_C environment, thus making these inputs safe for wiring from long distances such as from one side of a house to the other.

a: 16 light-duty relays with SPDT output terminal blocks. These are 2A relays, with all three points of the SPDT available via screw-type terminal blocks. 8 relays, $139 16 relays $179

b: 16 heavy-duty relays with SPST output terminal blocks. These are 8A relays, with both points of the SPST available via screw-type terminal blocks. 8 relays, $139 16 relays $169

d: 16 IO User prototyping board. This board has a Xilinx Spartan3 208 pin FPGA on it as well as a large .100" spacing prototyping area. This IO board is absolutely ideal for learning about FPGAs, and uses the same FPGA that will be used for future HCS_C designs. There are about 100 IOs available on this FPGA, so this IO board can be used as an IO expansion board if desired. $139 with XC3S50 $149 with XCS100 $169 with XCS400

e: 16 channel 10-bit ADC and 10-bit DAC IO board. The inputs and outputs are available via screw-type terminal blocks. $89

f: 4 output stepper motor driver IO board. Four motors, each with 4 stepper inputs, can be controlled by this IO board. The L293D stepper motor driver chip is used, so motors up to about 700mA per stepper input can be controlled for forward or reverse direction. $89

g: 8 input shaft encoder IO board. Up to 8 shaft encoders can be connected. The shaft positions are continuously maintained without any HCS_C processor intervention. $89

How do I hook up power to HCS_C?

The board has a position for a 3.3V regulator (LT1584CT-3.3). If you want, you can

jumper this and provide 3.3V directly (about 600mA for the base board), but I don't

recommend this, the regulator helps protect against accidental overvoltage (but not

reverse voltage!!) All loaded boards will come with the 3.3V regulator, I suggest

driving this with a +5V supply. The power connector has three pins, the outside pins

are ground, the middle pin is +5V. See the HCS_C Connection Users Manual for more

information on making safe power connections to HCS_C.
