msp430 lcd display supplier

Beijing STONE Technology co., ltd was established in 2010 and devoted itself to manufacturing and developing high-quality intelligent TFT LCD display modules.

Our vision is to become one of the world"s top display manufacturers in the industrial intelligent field. And providing top-quality products and professional technical services to customers all over the world.

Our core TFT LCD display modules integrate a CPU, flash memory, and touch screen in the hardware unit. Paired with an easy-to-use free GUI design software and complete instruction set, customers can avoid time-consuming accessories selection and system integration tasks. These units greatly reduce the workload in HMI development and make the entire process faster and easier.

The modules come with a UART TFT serial interface that can be controlled by any MCU through the simple but powerful instruction set like the 8051 series, AVR series, MSP430 Series, STM32 series, MC9S12, and Arduino series, among others.

Each TFT display LCD module has a wide range of applications, such as automated system control, vending machine functionality, intelligent lockers, electricity equipment (oiling machine, EV charger), elevators, smart home and office, precision instruments, and much more.

To date, we have delivered custom display solutions to over 3000 customers around the world. Our TFT LCD modules have been widely praised for their quality and performance and that is in large part thanks to our partners, including NI, Siemens, ThyssenKrupp, and many others. These long-term cooperative relationships have been mutually beneficial and we hope to continue a long history of success.

In this post will you find some basic tests with 16×2 LCD display using the MSP430. It is a widely used display controlled by the Hitachi HD44780. This display is able to show 2 lines of 16 alphanumeric characters.

Character LCDs use a 16 contact interface, commonly using pins or card edge connections on 0.1 inch (2.54 mm) centers. Those without backlights may have only 14 pins, omitting the two pins powering the light. The pinout is as follows:

The hardware assembly of this project is very simple. The commication with display is done using 8-bits or 4-bits, to save I/O pins is commonly used the 4-bit operation mode. In this case the data is send in two parts: first the upper nibble is sent and after the lower nibble is sent. The connection between LCD and MSP430 is as follow:

Communicating with LCD controller requires to follow a specific initialization sequence. The commands and timings must be respected in order to achieve a proper work in desired mode. The following diagram shows the initialization sequence for the JHD162A (The device that I utilized, some variations in timings can happens depending on lcd display manufacturer).

The full project can be downloaded in the GitHub. At this step you might set the development environment like shown in previous article. More things can be done to improve this code, specially removing the delays. As the LCD is a ‘slow device’, the microcontroller usually hangs much on delays during commands, this time could be used to make other tasks.

Alphanumerical LCDs are probably the easiest devices to quickly project information visually. They are easy to use and cheap. To be able to use them, we do not need any additional hardware feature of a micro or any special communication hardware like I2C and SPI. Digital I/Os are what we need to use these displays. Just like my other tutorials, this tutorial includes three LCD examples – one with software SPI communication, one with software I2C communication and one with direct DIO-based 4-bit LCD interface.

Be sure to use 3.3V compatible LCD because most of them don’t operate at 3.3V power level. Most of the LCD are designed for 5V operation. It is okay to use 5V power supply for powering LCD if there is no other option. LCDs accept 0V – 3.3V logic level. However, there should be no way with which a 5V power supply/device can get connected with MSP430’s 3.3V power bus.

Most popularly alphanumerical LCDs are driven in 4-bit data mode and this is what that has been done here. First let’s see some typical LCD instructions.

Since alphanumerical displays utilize GPIOs, there’s hardly anything to explain here. Try not to use GPIOs that have alternate roles because you may never know when would you need their alternative functions.

I am using a 16x2 LCD with an MSP430 and am unable to figure out how to print a value from my AtoD. My LCD is using the ST7066U driver, and the setup code for my LCD is this:

In my main code, I read an AtoD value, but I am not too sure how to display it. The AtoD works fine, I can use debug mode in Crossworks and see the AtoD value is what I am expecting. I can display text on the LCD with something like this:

I am a complete novice at this, and the code for setting up the LCD was taken from HERE and edited slightly to fit my MSP and setup. Essentially, I just want to do something like

I get an error saying too many arguments to lcd_print. I assume this means in my setup, I need to change something to the way lcd_print works, but not sure how to do this. Can someone please let me know how to edit this so I can do something along the lines of

This 3.2 inch TFT LCD Display module has a resolution of 320 x 240 pixels. The module includes Resistive Touch Screen Panel. SSD1289 is used to control LCD and the touch panel is controlled by XPT2046.The module can be interfaced with any MCU like STM32, AVR and 8051 using the 40 pins breakout header that Include touch panel interface. The module can be driven in 16bit data interface mode.

This LCD Module can be directly plugged into Arduino board using "TFT LCD Adapter Shield for Arduino" shield. The LCD on this module has a has wide viewing angle and a decent contrast ratio.
