By Lewis Loflin This is an Arduino version of my Raspberry Pi program. Both programs do not require any external libraries or hidden code and I believe more flexible. /* By Lewis Loflin [email protected] Electronics website: This demonstrates using direct coding and no external user libraries op operate a common I2C based LCD display with Arduino.

You already seen that by using our header file lcd.h, you can connect your 16×2 LCD to any of the output pins of the microcontroller. • In the firmware folder in the library you will find the.tft files: • 2.4' Nextion display 240x320Example.tft • 4.3' Nextion display: 272x480Example.tft • Copy the.tft file to a FAT32 formatted SD Card. Ensure that there is no other.tft file on the SD Card • Insert the SD Card into the slot and power cycle the display • The display should immediately begin to install the firmware • When the software is installed, remove the SD Card and power cycle the display again • The following image should appear on the screen. • There are only three full screen graphics loaded and they are referenced as Pictures 0, 1 and 2. See the section ' The Graphics and Image Cropping'. • There is only one page and it is referenced as 0. Its background has been set to Picture 0. • There are four components created: • m0 (ID:1) is a touch area. The only parameter changed is in the Touch Press Event -- Send key value is selected. • b0 (ID:2) is an image crop button. The default image 'picc' is 0. The Pressed image 'picc2' is 1. In the Touch Release Event tab the Send key value is selected. • b1 (ID:3) is an image crop button. The default image 'picc' is 0. The Pressed image 'picc2' is 1. In the Touch Release Event tab the Send key value is selected. • t0 (ID:4) is a text area with a solid white background, right aligned. The Pressed image configured to 1 is why the check boxes show the round grey circle when they are being pressed even though we haven't configured anything in the Arduino yet. Receiving a Message and detecting a Button. In the Nextion Editor there is a component called a Progress bar. There are several aspects that I don't like about the implementation. Rotor gene 6000 software engineer salary. First, it requires that one isolates the graphics for an empty and full progress bar and then add them to the Pictures in the Editor. Yj newsflash module rapidshare search engines download. Secondly, every time the progress bar receives a new value it erases the progress bar entirely and then repaints it. This causes a noticeable flicker even if it repaints with the same value. Hopefully, this will be fixed in the future. The three screens below are the ONLY graphical assets that were used in this project. Each screen is only between 17 and 19 kilobytes. Even the temperature progress bar states are included here. The first screen has all the graphics in their default or OFF states. The second displays both the buttons in their Pressed state. And in the third the buttons are shown in their Selected State and the progress bar is completely filled. How can this be? What if I want one button ON and the other OFF? How do I set the progress bar to 50%?
