I’m trying to test my Uno board and 8x8 led matrix with the MD_MAX72xx_HW_Mapper example of the library.
My hardware and my wiring is good, as I can run some sketches of the LedControlMS library
before. (so I changed the pin assignement in the MD_MAX72xx_HW_Mapper example)
The serial monitor show me this :
߸⸮BW⸮Cl<RVZJ⸮0O⸮@E\⸮Gr0⸮B0 n⸮G⸮⸮SR⸮B⸮⸮⸮Rb2CN4jFX ⸮B⸮ ⸮C%BZA⸮ T⸮⸮⸮QBGOBҀV⸮⸮r⸮⸮1B⸮\⸮Җ⸮ӑM⸮⸮⸮GCVe ]⸮⸮⸮⸮⸮⸮BABC⸮S⸮ x⸮Q]⸮⸮B⸮C YG⸮aF⸮BBA⸮FB⸮PT@ ⸮4FAB⸮G0C⸮rRQe
What could it be ?
