Get the pixel color value at a given, unrotated coordinate. Just did this for a feature in the ILI9341 library (but for a specific drawRGBBitmap() variant instead of drawPixel()) and seems OK, does the Expected Thing. thought some more about it: I'd globally define an encoding (as a #define) and use #if encoding == latin-1 / #endif to add code / data: UTF2ISO & ISO2UTF functions (not sure what the latter will be needed for, but it's in fact the easier translation since it's just reading UTF from an array) The former will be a lot of case statements methinks. The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays. h. Its not exhaustive and we'll try to update it if we find a really useful function. getRawPixel (int16_t x, int16_t y) const. ), font size in points (currently 9, 12, 18 and 24 point sizes are provided) and “7b” to indicate that these contain 7-bit characters (ASCII codes “ ” through “~”); 8-bit fonts (supporting symbols and/or international This is a helper library to abstract away I2C & SPI transactions and registers.
