The following two videos shows an interfacing of lcd display(with hd44780 controller) with parallel port and serial port respectively. A two softwares are used for both interfacing which can be downloaded
Hello All, I'm currently building an interface to hd44780 lcd, and needs PWM to drive the backlight. For some electrical rules on PCB, i can only set PWM at P1A/RC5, but i'm unable to get it done, even with ISIS Proteus simulation, its outputs nothing. Here is the code for the PWM for lowest possible frequency, at 48MHz fosc: void Ini
If you are utilizing either the Microchip XC8 or C18 compilers, both provide the Xlcd library which supports either the 8-bit or 4-bit interface to hd44780 compatible lcds. You can find the source code for the Xlcd library in the: \sources or src\plib or (...)
Recently i have purchase a 16 by 2 lcd display,that is DT1602C. I connected the pins of lcd display to PIC and potentiometer.But the backlight newer turned on despite there is 5V voltage supply. My question is it hd44780 compatible ? Can it interface with a 5V pic and potentiometer ? Thank you.
its a simple lcd 16x02 It's surely hd44780 compatbile, but you should pay attention to the port expander/interface chip shown on the photo in your initial post. It decides if you can use the built-in mikroC libararies or need to write something on your own.
You need to familiar with lcd hd44780 first.
I don't think you will find any place in the world that does not have a hd44780 compatible lcd. In addition, you'll also hardly find an alphanumeric lcd display with byte parallel interface that doesn't use a hd44780 compatbile controller. In so far, the thread is imagining non-existing problems from the (...)
The following is a tutorial demoing an hd44780 compatible lcd using 4-bit interface with the 8051 family and provides source code in both Assembly and C languages: lcd interfacing with Microcontrollers tutorial Typically, black boxes/rectangles indicated an initialization
The hd44780 chipset offers either 8-bit or 4-bit data I/O, not 16-bit. The interface and coding method is similar to utilizing the device with an 8-bit PIC. There are numerous hd44780 compatible lcd libraries available. Are you coding in C or Assembly Language? If C, what compiler are you using? BigDog
For driving motor you can build discrete H-bridge (which is general way to control DC motor rotation direction) or use some integrated bridge like L298, LMD18201 or similar. For buttons see any microcontroller related tutorial, this is the most basic thing ever. As for lcd, if is has hd44780 compatible controller (which i'm almost sure it has) you
in JHD162A JHD is the Company Name/etc 162 mean 16x2 but this lcd uses the same controller hd44780
I hooked up a Hitachi hd44780 based 2x16 lcd with PIC18F2420. Now on the bootup, I should see boxes in the top row (Typical for a hd44780 based lcd). But what I see is 8 boxes in top row and 8 boxes in Bottom row. Is the lcd Blown or something else is wrong? I have attached a snapshot of (...)
I think the question title is misleading, you apparently mean interfacing the hd44780 in Verilog, not implementing it? If the project possibly implies designing a hd44780 model for test purposes (you don't clearly tell about this point), it can only apply to the digital part (bus interface and controller) not the analog part (...)
Most lcds have similar setups, take a look at these examples: FPGA4Fun's lcd Tutorial Interfacing hd44780 lcd PDF These should get you rolling.
Dear all, I want to use a hd44780 for a hobby circuit. So I have connected with my PIC MCU in a 4-wire interface and tried to communicate with it. However I cannot display anything on the lcd. I will try to troubleshoot my design but I need to know something pretty important! I cannot understand whether the lcd has (...)

PIC16F877A microcontroller connection with hd44780 lcd,C code for programming PIC16F877A to interface lcd
Hi all, I've see that many people have trouble about lcd interfacing, I've just finish to develop a library to do all the things needed to drive a hd44780 lcd controller based display with a PIC. My application is able to work with 4 bit interface (in order to save 4 pin of the microcontroller) and also isn't restricted to (...)
Most of the lcds use the standard hd44780 chip or the KS which is also hd44780 compliant chip. Here is a zip file that might help you in interfacing the lcd with MCU.
I have used this page several times and it should help with building an interface library for a hd44780 lcd. Sadly, I do not know any examples for that particular compiler...but there are many out there for other PIC compilers which should be helpful even if it isn't a direct copy & paste.
