#161754 - LED Maxtrix Driver |
HI all,
I would like to drive an array of LED 7x5 (or 8x8) LED Tiles (Matrix configuration). Here's what I have so far 
Operation MCU pulses RESET to reset the ring count to 0 MCU clocks the ring counter to drive C1 high MCU send SPI command to SPI led driver to select LED's in the C1 string MCU truns of C1 string of LED MCU clocks the ring counter to C2 MCU send SPI command to SPI led driver to select LED's in the C2 string . . . etc I'd like to drive 10 tiles in a row... What can you suggest to for driving an array of tiles. I've looked at the single chip Maxim parts but there about $10~$15. Thanks in advance Joe |

| Yes - MOSI and MISO should be swaped | 01/01/70 00:00 | |
