[Elphel-support] change camera parameters through Telnet

[support-list]

>how could I change the EXPOS value with Telnet without the need of php or wget?

You may write a C application, copying some code from the PHP extension code, providing the mmap access to the data structures and handling the FPGA pipeline operation (there are actually two 8-deep pipelines - for FPGA internal commands and the sequence of the i2c commands sent to the sensor during particular frame.
Even such simple operation as changing exposure time should be synchronous to other parts of the camera. Some interactions with the command queues can be done by just using fseek operation to device drivers (seek relative to end of file beyond the end of file has special meaning in many of them), but using PHP is much easier as the functionality is already there. What kind of problems do you have wit the current interface so you want to re-implement it?
