![]() The standard TP4056 is set to allow up to 1Amp of charge current into a 3.6v battery. Lithium Polymer batteries require a current limiting charging circuit to avoid overcharging and damage. ![]() The only two main challenges are to ensure the hookup wire is adequate for the location of devices within the case and ensuring that the Battery does not short out when arranging the components in the case. I have also included a version of code for the standard ILI9314 displayĬircuit assembly is relatively simple. If problems persist message me and I will try and assist. If the orientation of the screen is in portrait then row 105 in code can be adjusted.If the colours are incorrect check they can be changed after row 60 of the code.If the touch locations are incorrect then row 218 of the code provides test coordinate data which can be used with Row 39 min/max settings for touch accuracy.If the screen is not working then you may need to change the screen type in the code to ensure correct operation.Test that the colours and touch locations of the touch screen are consistent with the video and pictures provided. I had quite a challenge with this particular model getting it working and had to make a number of configuration changes before I could get it working satisfactorily.įortunately, Adafruit has provided a variety of options to deal with these challenges however you may find some issues you may have to deal with. TFT LCD Screens come with different control chipsets and touchscreen setups. Calibrate Screen colours and Touch Locations Adafruit_TFTLCD.h - Arduino library for 8-bit TFT LCDs ģ. ![]() ![]() Adafruit_GFX.h - Adafruit GFX graphics core library.The code requires the following three libraries to be loaded into the Arduino IDE to enable it to work In the picture provided, you can see the correct alignment including the noticeable gaps in the Uno and TFT screen pins that help with alignment.įirstly download and install the Arduino IDE from here ![]() I have subsequently found there are various screens available that have different drivers or settings so here is my recommended approach.Ĭarefully align the Arduino Uno and TFT screen pins and ensure they are oriented correctly. The best place to start is to connect the Arduino Uno with the TFT screen and test the screen. ![]()
