Hardware setup for the Arduino Mega

Updated Mar 23, 2010 by acle...@gmail.com

See ArduinoDiecimilaHardwareSetup for the other pins on the Tlc that need to be connected.

Required Pins

Mega pin 51 (MOSI) -> SIN (Tlc pin 26)
Mega pin 52 (SCK) -> SCLK (Tlc pin 25)
Mega pin 11 (OC1A) -> XLAT (Tlc pin 24)
Mega pin 12 (OC1B) -> BLANK (Tlc pin 23)
Mega pin 9 (OC2B) -> GSCLK (Tlc pin 18)

Optional Pins

VPRG - for setting dot correction (per-channel current adjustment)

Mega pin 50 -> VPRG (Tlc pin 27)

XERR - for checking for thermal overloads or disconnected LEDs

Mega pin 10 -> XERR (Tlc pin 16)

Wiring Diagram

Anyone want to modify the SVG of the Arduino Diecimila?

Do I need to change anything on the IDE side ? This library isn't working for me on my Seeeduino Mega. I am using Arduino 0017 on Linux and connections as per the above. There are no error messages but nothing is happening either. Also, I can't find the Tlc5940.o file that needs to be deleted for new settings to take effect.
