Hello,
I'd like to control 7 10-led-bargrah to display some visual effects. I chose to use MAX6955 to drive them, it works by the serial interface I2C. I also use the stm32 discovery board.
I followed the datasheet of the MAX6955 to make the wiring :
- I connected the cathodes of each bargraph together i followed the "Connection Scheme for Sixteen 7-Segment Digits" from the datasheet.
- I took my I2C routines from another project that is working properly just made a few changes to fit to...
