This is a low-cost sensor very easy to use. ILI9341 SPI TFT Display Sample link to ILI9341 Sellers usually refer to these as “driven with at least four IO” What we need for this design is a model with an SPI pin configuration. Anyway, I think the one is being sold now is perfectly compatible with the previous model. The only difference is that the one you can find now implements a set of pins to control a touch panel (though they say at the product description “non-touch”). Workaround: once Arduino IDE tries to upload the schema, press BOOT and without releasing it press also EN button, wait for a half second, release EN and when IDE stops waiting and starts the uploading you can release BOOT button.Īgain, the component I had at home was about one year old. But, these boards have a bug design: they don’t allow uploading schemas directly from Arduino IDE ( Error: Timed out waiting for packet header) and you have to ‘play’ with EN and BOOT buttons every time. I tested voltage on each significant pin (D/C, CLOCK, MOSI) and no result.įinally, I decided to give a try one of the last boards I bought: the model on the left side. I tried multiple pin configurations, alternate libraries loading order. After 3 or 4 display operations (text, area fill, …) the screen went always blank and only when WiFi library was loaded. When I first tried to put all the components together I noticed that ILI9341 TFT Display and WiFi connection were not good friends working at the same time. It is a board I bought a year ago and it was working fine (for small tests) since then. The first one was the one on the right side. ESP32 Development Board: I’ve tested two different boards, and though they are very similar the results were not the same.No resistors, capacitors, diodes… no discrete components apart from 3 five cents of € coins. Claudio consists of just five (or six) components, the wiring between them and code.
