In the graphic screen on the ferduino there are no values of the temperature only 2 blue and 1 red line and the yellow time line .
I changed the line
Code: Select all
card.init(SPI_FULL_SPEED, ChipSelect_SD);
to
Code: Select all
card.init(SPI_HALF_SPEED, ChipSelect_SD);
because i use the card reader on the tft screen.
but still no data on the graphic.
