On how to wire up ILI9341 TFT LCD to ESP32. Special thanks to XTronical for his video Turn LED on/off with Blynk app on smartphoneĬompiled and tested with VS-Code (PlatformIO) on ESP32-WROOM-32D. Humidity & temperature sensor/module DHT22ĮSP32 CN -> Capacitor -> GND // No need to press Boot button to upload sketchĮSP32 13 -> 1kΩ resistor -> GND // For fun. Measures temperature and humidity using DHT22 sensor.ĭata is displayed on KMRTM28028-SPI - 2.8" TFT SPI 240x320.Īlso, a LED is added to play with Blynk on smartphone. But "Components and Programming - I/O Devices - Sensors - Modules" seemed like a good fit.ĭisplays current date and time using ntp sync via internal WI-FI.
Please do not take the fact that it got moved as you have done something wrong on the forum! I myself still struggle from time to time in trying to decide the best place to post a comment.Īnd this could still not be the "best" place for this topic. This has worked fairly well fo the displays I have used, but don't know if it will for sure solve your issue.Īs you can now see these two posts have been move to a more appropriate thread. This is a programming issue that I have used a variable to determine if the data to be displayed has changed since the last time I wrote information to the display and if the data hasn't changed then no write occurs. While I have not used the exact display you mention, the displays I have used can have a "flicker" issue if you are writing to them more often than needed. So perhaps these two posts should be moved to a more appropriate thread. Sure that this issue is worthy of a video to explain.
