Text on MikroElektronika 8x8 LED click

Hello,

I connect am equivalent of MikroElektronika 8x8 LED click to PIC Iot and I display the sensor temperature.
But I see that I can display only numbers.
Do you know if it is possible to display text as well? Or ascii signs?
And, for this 8x8 led matrix, it is any possibility to change the speed, brightness and display static text/numbers/signs ? I know thsi it is possible if I use code directly, but my question is related to Atmosphere IDE.

Thank you,
Mihai
