The raspberry pi camera module v2.1 had two "special" signals on the 15pin flat cable. This is at pin 11 and 12 (sometimes called CAM_GPIO and CAM_CLK but I don't know for sure). While the camera itself has two special pins one for the FSTROBE (the flash) and one GPO (not idea where that is for).
- I need the FSTROBE for connecting a flash light (and other things) but is this connected to one of the pins at the 15pin flat cable?
- What is the meaning of the pin 11 and 12 in case of the V2.1 sensor?
- If I capture a still image with "raspistill --raw -o image.jpg" will the FSTROBE be triggered and passed on to one of the pins of the flat cable, or is FSTROBE disabled by the driver of the IMX219?
