Hello,
I've got an issue with my MAX7219 chip connected on my MCU (STM32). I'm programming in MikroC for ARM, and I've got working code for my led matrix which displays some random text when I turn on my mcu. But sometimes when I run my mcu, my led matrix just displays all 8x8 leds are constantly on, and nothing changes.
Does anyone know why this could happen to me?
I've attached my code if it could affect solution.
P.S. If I can somehow notice, this happens always after some period while mcu was turned off, and after that when I switch off - on my matrix will display right screen
For any further information, free feel to ask me.
Thanks in advance
