如何将uint32_t转换为char*类型?

Hello i am using an Arduino UNO with an adafruit shield to display score values but the function used to display scores only accepts char* values and the score itself can occupy up to 6 digits(000,000 to 999,999). i have tried using sprint() but i have had no luck since the screen will flicker like crazy. i believe the problem to be that chars only hold a certain number of bytes that could not fit a 32 bit int but i would think their is a way around this. draw text is the function used by the shield to drawstuff on the screen with input being char*, color code, size, x pixel, y pixel. if anybody can please help me convert between these two types please let me know. also if their are alternatives that would also help me.Hello i am using an Arduino UNO with an adafrui
