// SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS // line below so it is NOT defined. Other displays such at the ST7735 require the TFT CS pin // to be toggled during setup, so in these cases the TFT_CS line must be defined and co...

When I tried to Google “Arduino data logger“, the first few results would tell me about saving it in an SD Card. SD Cards are an excellent option but you need to manually transfer the reading from your SD card to some application like Excel to do the processing. ...

SD card and plotting them even faster as the typically the RLE compressed files will be significantly smaller than a raw bit map. Potentially icons could also be stored in FLASH as well. As an example a raw image of 60 x 60 pixel icon is 7200 bytes, RLE of a simple graphic of a ...
