Refer to eBay Return policy for more details. Dynamic contrast control Unlike other common graphic LCDs the contrast for the ST is set by an internal resistor divider. Search by Tech Spec Search by size, controller, interface, etc Ask our product support team We’re here to help! It is necessary to connect RESET to the microcontroller as the initialisation procedure involves toggling this pin. Contact the seller – opens in a new window or tab and request a shipping method to your location. The internal booster can provide from 2x to 6x the input voltage depending on how capacitors are connected between the CAPxx terminals. Improving efficiency Refreshing the screen involves sending the entire local buffer to the screen RAM.

SPI mode provides an easy mechanism to drive the screen using few pins. Basic operation software SPI mode provides an easy mechanism to drive the screen using few pins.

“COG Display x64 Blue LCD Module Arduino,STP,White on Blue

Only registered users can write reviews. The measurement shows The datasheet I used can be found here.

After this a quick trick is to write a single byte and see how it is displayed. It is necessary to find a value between 0 and 7 which works well with the specific st756p5 as this is used with the dynamic contrast feature.


The tutorial follows the same path I took whilst developing a simple library for a screen I had bought.

The first position in our array is at the top left of the screen. Voltage boosting and regulation The ST has an integrated voltage booster charge pump circuit that can provide the high voltages s7565p by the liquid crystal display. Help other Logicware Pty Ltd users shop smarter by writing reviews for products you have purchased.

As the screen has 8 pages the most efficient method on a small microcontroller is to send only the st75655p which have changed.

Download the ST7565P LCD Controller Datasheet

If you are using an Arduino, install the ST folder which contains the library and an example sketch. In this tutorial we assume you’re using a 5V microcontroller such as an Arduino, if your chip is runninag wt7565p 3v, you can basically just ignore the and do everything else!

However this is inefficient if more than a single bit or pixel is set in the same byte in subsequent operations.

Sr7565p item will ship to United Statesbut sr7565p seller has not specified shipping st7565pp. Resume making your offerif the page does not dt7565p immediately. Report item – opens in a new window or tab. See all condition definitions – opens in a new window or tab Please enter a valid ZIP Code.


The picture below shows the same font demonstration as above, but with the inverse feature turned on. We have a display for that! The steps required are: Download it from github – click Download Source to grab it all. Warranty is void and no repair or replacement is granted under the following conditions:. We’re adding new displays all the time.

This maps nicely to the software buffer required for caching the screen contents because each page is a byte high. A number of reasons could produce the difference between our calculation and the physical measurement:.

Notify me when back in stock. Learn more – opens in new window or tab. Impatient readers can check my graphics library Doxygen documentation can be found here. A quick check is to send constant bytes of 0xFF to fill the screen. This has 8 steps and regulates the reference st7556p used to drive the liquid crystal display.

The th byte in the array Array[] is on the first page at the right hand side of the screen.
