The CFA633 series of advanced display modules will be changing from the current firmware v2.1 to v2.2. Design changes were made for backwards compatibility.
The CFA633 series of advanced display modules will be changing from the current hardware v2.0 to v2.1. Design changes were made for backwards compatibility.
As part of our continuous improvement, design changes have been made to the hardware of the CFA633 series of advanced display modules for improved manufacturability, improved quality, and a lower current profile.
As part of our continuous improvement process, Crystalfontz America, Inc. is releasing a new version of firmware for the 2v0 hardware based CFA633 family of intelligent modules.
Customers with Defined Part (DP) numbers will not have their modules shipped with this new firmware automatically. Please contact our engineering support team at support@crystalfontz.com.
As announced in a PCN 10286 https://www.crystalfontz.com/news/pcn.php?id=10286 on 2010/10/06, the new CFA633 hardware v2.0 / Firmware version 2.0 ("s2.0" for serial modules and "u2.0" for USB modules) is fit, form, and function compatible with previous versions of the CFA633 series (hardware versions 1.5x).
In command 5 (0x05): Reboot CFA633, Reset Host, or Power Off Host, the module now knows if it is coming from a power up or from a reset. This in turn improves the bootup sequence. A note was added to describe the brief delay at bootup when more than one of the optional fans are on.
In command 12 (0x0C): Set LCD Cursor Style, cursor style choice "3" changed from "3 = blinking block plus underscore" to "3 = blinking underscore cursor." The rate at which the cursor blinks is faster than in previous CFA633 versions (HW v1.x).
For information on additional changes, please see the Data Sheet’s Revision History. For a technical bulletin comparing CFA633 modules by version number, see PCN 10291 at https://www.crystalfontz.com/news/pcn.php?id=10291 published 2010/11/10.
The attached PDF file describes differences between our CFA633 v1.5x and CFA633 v2.0 intelligent display module series. We also list the CFA533 series as a comparison for customers who do not require the fan control available in the CFA633 series. Hardware version numbers are silk screened on the back of the PCBs.
The LCDduino board enables users to create many applications/projects that require a 16×2 LCD display and Arduino. The board has the exact size of 16×2 LCD and can be installed on the backside of the LCD. This is a low-cost solution that has onboard Arduino + LCD so no extra Arduino Nano or Arduino board is required. The Arduino compatible hardware includes onboard programming and boot-loader connectors, Atmega328 microcontroller, and 16×2 LCD interface. Each Arduino I/O Pin including the VCC and GND is exposed to the connectors for easy connection with sensors and other devices. The board enables the easy interface of many devices and sensors. The operating power supply is 7 to 15V DC.
This serial LCD kit includes a 16x2 LCD together with a small "serial interface" PCB fitted with a PICAXE-18M2 chip. The on-board PICAXE-18M2 chip is provided pre-programmed with the open-source AXE133 firmware, which allows this on-board 18M2 chip to act as a "slave" serial driver for the LCD display. This allows your main project to display text on the serial LCD via simple serout commands, such as
The control codes are identical to our popular AXE033 module, so this kit can be used as an altenate to the AXE033. On this board the slave chip is a completely normal 18M2, so it can also be reprogrammed whenever you want (e.g. to change the power-up welcome message or even temporarily "borrowed" for another project!). Click on the resources tab above to download the AXE133 BASIC firmware file.
16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. But the most used one is the 16*2 LCD, hence we are using it here.
All the above mentioned LCD display will have 16 Pins and the programming approach is also the same and hence the choice is left to you. Below is the Pinout and Pin Description of 16x2 LCD Module:
These black circles consist of an interface IC and its associated components to help us use this LCD with the MCU. Because our LCD is a 16*2 Dot matrix LCD and so it will have (16*2=32) 32 characters in total and each character will be made of 5*8 Pixel Dots. A Single character with all its Pixels enabled is shown in the below picture.
So Now, we know that each character has (5*8=40) 40 Pixels and for 32 Characters we will have (32*40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels.
It will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780 is used, which is mounted on LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen.
The LCD can work in two different modes, namely the 4-bit mode and the 8-bit mode. In 4 bit mode we send the data nibble by nibble, first upper nibble and then lower nibble. For those of you who don’t know what a nibble is: a nibble is a group of four bits, so the lower four bits (D0-D3) of a byte form the lower nibble while the upper four bits (D4-D7) of a byte form the higher nibble. This enables us to send 8 bit data.
As said, the LCD itself consists of an Interface IC. The MCU can either read or write to this interface IC. Most of the times we will be just writing to the IC, since reading will make it more complex and such scenarios are very rare. Information like position of cursor, status completion interrupts etc. can be read if required, but it is out of the scope of this tutorial.
The Interface IC present in most of the LCD is HD44780U,in order to program our LCD we should learn the complete datasheet of the IC. The datasheet is given here.
There are some preset commands instructions in LCD, which we need to send to LCD through some microcontroller. Some important command instructions are given below:
