Project Callisto: LCD Text Simulator Post author By whitespace Post date January 9, 2023 Project Callisto is a basic LCD project started by me (UI UX) and my husband (software engineer). He designed a board attached to a small screen that can perform basic functionality such as:- AM / FM Radio- Wifi- Music from SD Card feature- Sensors (temperature, humidity, etc) The Problem: 1. Because the device has limitations, in order for text, symbols, and numbers to be displayed on screen (whether it was an input by the useror a device displayed output), PNG files of these letters, symbols andnumbers needs to be stored. 2. The PNG files of the letters, symbols and numbers are built in Figma and exported as a ZIP file and sent via email which is then extracted andre-uploaded for testing. This is time consuming as sometimes thesePNG files have the wrong spacing, weird positioning, etc. which requires re-making the PNG files and re-testing time which eats intodevelopment time. The Text Simulator: - Export all PNG files from Figma and store them in a folder. - Open the text simulator.exe and click on "Pick Folder". - Select the folder that contains the PNG files and click on "Select Folder". - The simulator will display how your PNG files will look in the LCD screen. This helped me finalize the perfect PNG files to be used in the project. The simulator will show you the letters, numbers, symbols side by side or in combination in a sentence so you can see which letters have weird spacings, etc.
