so there are three stages or three levels of information: Sensor, FPGA, and software isn't it?
let's say I don't care that much on the software that runs on the camera, is it possible to control both FPGA and sensor with a single set of tools via de command line? or maybe run a process that keep control of both sensor and FPGA asynchronously. when I call the pixel binning summing process with this "fpcf -i2cw16 4820 0x60" i'm calling the FPGA isn't it? where "0x60" is a value and I guess "4820" is a process (in this case "pixel binning summing") in the fpga, and I guess "-i2cw16" is the sensor? 2012/12/13 support-list <support-list@support.elphel.com> > ** > Hello Biel, > > By "through telnet" you mean "from the command line"? > > The simplest way is to use wget, like we do in init scripts, here is an > example: > wget "http://localhost/i2c.php?bus=1&raw=0x2000&data=0x7f"; -O /dev/null > >/dev/null 2>&1 > > You see - changing parameters otherwise is tricky - there are no "current > parameters" in the camera because of the pipeline operation.
