Video Experimenter and CAN Bus Shield

Hello all,

I have an Arduino Uno + Video Experimenter (Master Shield SPI_CS_PIN D9) + CAN Bus Shield (Slave Shield SPI_CS_PIN D10) and I will draw Information as an Overlay receiving from CAN. The Code for the Overlay works fine and also for the CAN…separately.

The Problem is, when I merge the Code it doesn´t work. I find out that the Problem is inside the “initOverlay()” function:

// Enable input capture interrupt
 TIMSK1 |= _BV(ICIE1);

When I comment out this line, the CAN Bis Shield works but the Overlay is missing. If anyone has an Idea?

Thanks!
