LCD Module in 4-bit Mode
In many projects, alphanumeric LCDs driven by Hitachi's industry-standard HD44780 controller are utilized. These displays can operate in either 4-bit or 8-bit mode. In 4-bit mode, only the high nibble (D4 to D7) of the display's data bus is employed....
LCD to a PC Parallel Port
The circuit is pretty simple. The data lines on the LCD match up well with the data lines of the parallel port, and extra parallel port I/O lines can be used to simulate the RS, R/W, and E signals on...
display and serial interfacing of
This hardware is designed to display the number of cars in a parking lot. The system utilizes a six-segment display; however, a single display is sufficient for the intended function. It employs the segment driver IC SN7447AN along with a...
Game-scoring Display ScreenCircuit
The game-scoring display screen circuit diagram is depicted in the image above. The circuit consists of an add/subtract scoring input circuit, an add/subtract scoring circuit, a counting-decoding display circuit, and a reset circuit.
The game-scoring display circuit is designed to facilitate...
Interfacing LCD via SPI
Over time, microcontrollers have become increasingly powerful, cost-effective, and compact. A typical microcontroller from the past may have had 40 pins and lacked internal memory, whereas modern J-series PICs feature 96K of program memory and only 28 pins. This allows...
interfacing lcd
The EN line is referred to as 'Enable'. This control line is utilized to indicate to the LCD that data is being sent. To transmit data to the LCD, the program must ensure that this line is low (0), then...
Build your own LC-Display
For the wiring of the display, the ribbon cable is first taken and soldered according to the circuit diagram on the 25-pin sub-D (parallel port) plug. The small circuit diagram illustrates the rear side, which is the solder side of...
LCD 7 digit HF counter
The resistor between basis and collector (around 47k) is to be individually set according to transistor characteristics. Without PIC in socket at the collector should be 2.5 V.
The circuit described involves a transistor configuration where a resistor, typically valued at...
LCD to LPT board
The LCD2LPT with Lirc circuit is the compilation of two circuits found on the net on a single board. The first is LCD to LPT interface and the second an IR remote control interface using http://www.lirc.org program. The main circuit...
