![]() ![]() To wrap up the series, we’ll install it on my son’s Manco two-seater and do some basic tuning. The finished controller uses the Nextion display as a programming and tuning tool, including many features found in professional products. In Part 5, we’ll cover tach signal input, reading vacuum for load, and other hardware. ![]() The 3.5” has 320x480 pixels which is large enough to fit table cells and other controls. The 2.4” used previously is too small for this project. We’ll use the Nextion 3.5” Basic display. While peak power is about the same, the “area under the curve” increase is truly amazing! To program the table while testing (driving) requires a Human-Machine Interface (HMI). A timing table allows changes in timing as engine parameters change (like a car). Of course, a simple controller could change ignition timing by turning a knob, but it would still only meet Best Mean Timing (BMT) within a narrow window of engine operation (which is what happens stock, and why we need this controller!).īesides, advanced timing could cause engine damage at higher loads and RPM. While this article qualifies as “Nextion Part 3,” it also qualifies as “Build a Small Engine Ignition Timing Controller, Part 1.” Small engines have a fixed ignition timing, as the magneto is solidly bolted to the engine. He spent considerable time working with me to give you the best information possible. I need to thank the Nextion North American Distributor, Patrick Martin again for his invaluable help in crafting the code for this article. The Editor Guide covers installing the IDE, configuring a new project, and using the Toolbox items. ![]() Nextion’s website is, where you can download the latest IDE, Instruction Set, and Editor Guide (and purchase products). Anything new in the v0.59 IDE will be covered as applicable. I suggest reviewing the first two installments and the new Editor Guide to refresh your memory on basic commands, as this article makes assumptions. Since writing Parts 1 and 2, Nextion has updated their Integrated Development Environment (IDE, Version 0.59 as of this writing), Instruction Set, and Editor Guide. In this installment, we’ll make it sizzle. » Skip to the Extras Give Your Nextion a Look of Class!īack in Part 1 of this series, we designed a simple Nextion display screen and got it to do stuff. ![]()
