Code breaks at set datasize about liveov7670_stm32

[stevstrong]

What do you mean under code "breaks"?
What is the last information displayed on the screen?
SPI.setDataSize() only sets some registers, it cannot hang.
So most probably the program stops somewhere in your loop.
Insert some Serial.print() messages to track where exactly it stops.
And double-check your connection, maybe the sync signals are not detected.

Hi, Thanks for the response. I tried Serial print and find that the program does not move beyond camera.waitForHref(); When I uncomment this line the displays shows a black screen with one line of pixels to the left, which sort of changes pixel color when pointing the camera at something.
HREF is connected to PB3 and every other pin is connected and checked. PWDN is GND and RESET is connected to VCC. tried them floating and had the same result.

It looks like the camera is not working correctly, as it does not provide the sync signals.
You should check the pixel clock which comes from the camera, and the other sync signals, too.
