This is a card with 4 RF input connectors and 8 tuners and 16 demodulators incorporating 2 STID chips. it can deliver 16 full transport streams from 16 muxes on 4 satellite bands simultaneously. With neumoDVB 16 or more services can then be tuned simultaneously from all of these muxes.New drivers were needed to handle conflicts between the tuners, as they share the LNBs and should be careful not to make contradictory decisions regarding sending 22kHz to switch between high and low bands or to send conflictingdiseqc commands. neumoDVB itself still needs some modifications to make use from this, but by being careful in starting the muxes (not all at once), it can already working.  Here is a screenshot showing 18 services from 16 muxes selected from 52E, 30W, 19.2E and 28.2E.To add to the complexity, neumoDVB itself was running on a remote computer and all of this was streamed over WIFI.It works, but the frame rate was not great.[ATTACH=full]156153[/ATTACH]The code needs some more work before releasing itThe new code also can show useful information about the internal state of the drivers via sysfs[CODE]$cat /sys/module/stid135/card0/statecard_no = 0 dev =00000000a81f1a57use_count = 2chips: 0000000064275c6e 00000000dc378979rf_in[0]: use_count=4 owner=-1 controller=0 voltage=0 tone=1rf_in[1]: use_count=3 owner=-1 controller=0 voltage=1 tone=1rf_in[2]: use_count=4 owner=-1 controller=1 voltage=1 tone=1rf_in[3]: use_count=5 owner=-1 controller=0 voltage=0 tone=1====[/CODE]This shows that all 4 rf_inputs are in use on 4 LNB connections. use_count is the number of demodsconnected to an rf_in. The total is 16, showing that all demods are in use. All rf_inputs, except 2,  are controlledby the first stid135 chip, which means that this chip is responsible for diseqc and 22kHz sending. Voltages are controlled by the FPGA on the card.[CODE]cat /sys/module/stid135/card0/chip0/statecard_no=0 chip_no=0 addr=0x68 i2c=00000000b5b88f76use_count = 8 mutex_locked_by=-1 at FE_STiD135_GetBer:1518tuner[0]: use_count=4 power=1 active_rf_in=0           rf_in_use_count=4 voltage=13V tone=offvglna=0 control_22k=1tuner[1]: use_count=3 power=1 active_rf_in=1           rf_in_use_count=3 voltage=18V tone=offvglna=0 control_22k=1tuner[2]: use_count=0 power=0 active_rf_in=-1vglna=0 control_22k=1tuner[3]: use_count=1 power=1 active_rf_in=3           rf_in_use_count=5 voltage=13V tone=offvglna=0 control_22k=1[/CODE]So on the first chip only 3 tuners were in use[CODE]$cat /sys/module/stid135/card0/chip1/statecard_no=0 chip_no=1 addr=0x68 i2c=00000000abb9b0e1use_count = 8 mutex_locked_by=-1 at FE_STiD135_GetBer:1518tuner[0]: use_count=0 power=0 active_rf_in=-1vglna=0 control_22k=0tuner[1]: use_count=0 power=0 active_rf_in=-1vglna=0 control_22k=0tuner[2]: use_count=4 power=1 active_rf_in=2           rf_in_use_count=4 voltage=18V tone=offvglna=0 control_22k=0tuner[3]: use_count=4 power=1 active_rf_in=3           rf_in_use_count=5 voltage=13V tone=offvglna=0 control_22k=0[/CODE]On the second chip only 2 tuners were in use.neumoDVB and the drivers decide which tuners to use. As there are only 4 input bands, there is no need to use more than 4 tuners, except when all demods on one chip are fully used and the second chip comes in action.Then more tuners must be started...</blockquote>
