Hi there,

does anyone know how to read the bits (pixels) from the fonts in picomite? For example to print big characters with "#" (like on printers in the past ...) or to display a letter on the 8x8led ;-)

# # # # ###### # ##### ### #####
## ## ## ## # # # # # # # # #
# # # # # # # # # # # # # # #
# # # # # # ###### # # ##### # #
# # # # # # ####### # # #
# # # # # # # # # # # # #
# # # # ###### # # ##### ### #####

If your display is suitable,
Print the text to the display then use the PIXEL function to read each pixel.

MM.INFO(FONT ADDRESS n) Returns the actual address of the memory location containing the start of the binary data defining FONT n

Then PEEK(BYTE addr%) to access the data.

The data looks like this. First four byte define the fontwidth,fontheight,first charcter in data, number of characters in font , the data then follows.

const unsigned char F_6x8_LE[580] = {
