Transparent Clear Acrylic Case for Nextion Enhanced 3.2 inch NX4024K032 UART HMI TFT LCD Resistive Touch Display Screen WIshioT

Most of the LCD touch displays are connected to the microcontroller either using parallel connections or SPI. This is because a lot of data has to be transferred to build up just one page. And because these displays are completely “thumb”, also after a small change, the whole page has to be built from scratch. Usually, the display routine is the biggest part of the sketch and takes a lot of time to build and debug. Recently I found an interesting new display concept to be used for Arduinos, ESPs, and other microcontrollers: The Nextion by iteadstudio.com. This is a series of touch displays which include a controller directly attached to the LCD and which can be connected to any microcontroller via a slow serial communication. And these modules are quite cheap, not much more expensive that a touch display of the same size without this feature. So, they should solve many problems: Nice lo
