<\/figure>\n\n\n\nPower<\/h4>\n\n\n\n
Each DNIN8 input duinoNode requires two power connections:<\/p>\n\n\n\n
- \n
- VCC<\/strong>, +5v device power<\/li>\n\n\n\n
- GND<\/strong><\/li>\n<\/ul>\n\n\n\n
Data Connections<\/h4>\n\n\n\n
DATA OUT: Each duinoNode requires three outbound connections for upstream (to the microcontroller) data transmission: Clock, Latch & Data Out.<\/p>\n\n\n\n
DATA IN: Each duinoNode offers three inbound data connections for receiving data from downstream input duinoNodes: Clock, Latch & Data In.<\/p>\n\n\n\n

DNIN8 Data Connections. Multiple boards can be chained together by connecting Data Out of a node to Data In of the next upstream (to microcontroller) node.<\/figcaption><\/figure>\n\n\n\n This version of the board accepts data connections at three port terminal blocks. Board-to-board data connections can be made with standard, 3-wire servo extension cable. <\/p>\n\n\n\n
Stacking<\/strong><\/p>\n\n\n\n
In addition to chaining board by wire, you can also stack up to 6 DNIN8 boards together to share the power and logic connections, and concentrate ports in one location. Stacking is enabled by soldering in 6-pin headers (included with the board) and soldering jumpers on each board in the stack.<\/p>\n\n\n\n

Close up view of the stacking jumpers, used to select input and output pins on stacked boards.<\/figcaption><\/figure>\n\n\n\n Successful stacking depends on setting the correct jumpers for each board to so that each board has uniquely assigned input and output pins.<\/p>\n\n\n\n
On the board that will be on the bottom of the stack, solder just one jumper to read input from a pin: we strongly recommend you select pins in numeric order, so solder the data in<\/strong> jumper at header pin 1.<\/p>\n\n\n\n

<\/figure>\n\n\n\nOn subsequent boards solder two jumpers: on the data out<\/strong> side, set the jumper for the pin corresponding to data in<\/strong> from below, then select the next pin on the data in<\/strong> side for reading from the next board.<\/p>\n\n\n\n

<\/figure>\n\n\n\nFollowing this pattern, you can mount up to 6 boards in a single stack. The top board of the stack does not need to select a data in<\/strong> pin, but can still connect to more upstream boards via wire connections at J2.<\/p>\n\n\n\n
Additional Notes about Stacking<\/strong><\/p>\n\n\n\n
- \n
- Connect power to the bottom board only.<\/li>\n\n\n\n
- The order of boards and ports is bottom to top, the same as if the boards were connected by wire instead of stacked.<\/li>\n\n\n\n
- To connect to another downstream board or stack by wire, use the DATA IN<\/strong> terminals (J2) on the TOP board of the stack<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Device Connections<\/h4>\n\n\n\n
The DNIN8 can be connected to standard buttons, switches and any +5v digital sensor device that produces a digital (HIGH or LOW) signal.<\/p>\n\n\n\n

Connection points for buttons, switches and digital sensors. All devices share the common anode power source but use individual Ground ports.<\/figcaption><\/figure>\n\n\n\n There are 8 device ground connections plus 4 shared VCC anode terminals to supply power to all attached devices. Simply connect a wire from VCC to the “hot” side of each button, switch or sensor, then the ground side from each device to individual ground ports. Pull-down resistors are already present on the board. <\/p>\n\n\n\n
Using the Board<\/strong><\/h3>\n\n\n\n
DNIN8 is an 8-bit parallel in, serial out shift register device. However,<\/em> the Arduino shiftin() library function is not compatible with shift register used by this board<\/em>. <\/strong><\/p>\n\n\n\n
The duinoNodes Arduino Library is free to purchaser of any duinoNode product. It will be added to your cart automatically and you will receive a download link when your purchase is complete. The library is delivered as a zip file; unzip it into your libraries directory, usually C:\\Users\\USERNAME\\Documents\\Arduino\\libraries. You will find example sketches in ..\\Arduino\\Libraries\\duinoNodes\\examples.<\/p>\n\n\n\n
