Send by parameter Char PROGMEM in fonction

[kammateo]

I'm trying to send a bit map to my function but I have an error: "call of overloaded "
Any ideas?
Thank you so much!

What Teensy board is this for?

In particular is it a T2.x or T3.x (or LC).

if 3.x/LC - then programem means nothing. Note: your array is of type "unsigned char" and your functions are "char" so you may need/want to make them the same.

If 2.x - Your function will need to do something to get the PROGMEM array into data memory to be used... Been awhile since I dealt with that.

Hi Kurt,
It was for A t3.5. I solved thank you
Is it possible to delete this post?
My error was

void GPSicon(uint16_t posX, uint16_t posY, char *text, uint16_t Width, uint16_t Height, uint16_t color)

The type was wrong:

void GPSicon(uint16_t posX, uint16_t posY, const unsigned char *text, uint16_t Width, uint16_t Height, uint16_t color)

Thank you so much Kurt
