Some of the projects I design make use of character displays. The Liquid Crystal Displays (LCD) I typically use are based on the Hitachi HD44780 LCD command set. Most HD44780 compatible LCDs use a standard 16 contact interface and are known as parallel devices. This project presents a design that allows the LCD to be controlled by a single serial pin from a microcontroller or a serial connection on a computer. Check out the project here

Hi! I work with engineering website EEWeb.com and would love to do an exchange of website links and feature you as a site of the day on EEWeb. Is this of interest to you?
Sure thing. This is an open site with open projects.
Thanks,
Curtis
I can be reached at brooksware2000@gmail.com if you need any further information.

Hi,
Like this to interface with Thermocouple item.
Can I get it a kit of parts
Cheers
Peter
Sure thing, I have a few pieces left to work out for the interface but, I will offer kits when complete.
Hi,
The thermoamp sits on top of another board? is it an Arduino?
Also has this been used with a Rasberry PI?
Cheers
Peter
Ps I’m a newbe
For the new design, everything is on a single board. Plugged into the board in the upper corner is a Bluetooth module that allows wireless communication. The other external board contains an LCD and menu buttons for manual control.
The previous design was all-in-one but has a connector that allows an external real time clock breakout board to be plugged in.
Let me know if this does not answer your question.

Hi Curtis,
Where does the code run?
The code for the LCD controller above runs on a PIC16F628 from Microchip. Controlling the LCD controller can be done over serial port by a microcontroller or Serial connection from a computer.

Curtis,
That now makes me even more interested in a kit.
Want to mointor cyliner head temps.
Please make a kit soon.
Cheers
Peter
I’m working on it. I need to make sure the firmware, software and case is solid before release.
Thanks for the interest,
Curtis
Where can I find the HEX file or compiler which I can use to get it?
I currently version 1.8
thanks
Compiler I used for the code is PicBasic Pro. The Hex files are in the download links.
