Which board (stock / gruvin9x / sky9x) are you using? stock

What is your open9x FW version? r1855

What is your open9x EEPROM version? 212-1

What steps will reproduce the problem? 1. press left long to enter General Settings on Transmitter 2. on first page press down key 3. after the sound options, I expected the Input Filter option, but it is not there.

What is the expected output? What do you see instead? The expected output should be an menu item called "Input Filter" with the options Single, Oversample and Filter. Instead of this, this menu item is missing. Also in the other pages no such settings can be found.

Please provide any additional information below. Interestingly the option is available in Windows program companio9x. And this option actually works if you alter it on the PC and load the settings afterwards to the transmitter.

This option has been removed in new versions. This part of the code has been reworked (Issue 164)

Right. Romolo removed the input filter option from c9x today

First I want to say, thank you for doing all of this. It's nearly perfect in every kind. Also how you handle issues reports, etc. very professional.

Please let me r comment on this topic. I tried to understand a little bit the rework based on issue 164. As far as I understand you reduced the latency a lot, which is really good. On the other side, the original meaning from er9x (I think it's the branch which invents this option) the input filter option also increases the resolution. I still see the higher resolution, because the output values have a digit more if the option is enabled. That's why I think it is still working, even not visible. So in the output display you see 100,0 instead of just 100. The simulator in companion9x does not show this difference. Are you really sure the old mechanism is removed? What is about the resolution in the new mechansism. Quite interesed.

The new inpu system is in my opinion the best we will able to have on the 9x. The "filtered" option was completely wrong. The "oversampled" option was the best. So it's the one we choosed at the time. The latency is not increased as described in issue 164.

Also update documentation.

Actually true I checked again, and there is no difference, whatever you choose in companion9x. Please also update the documentation, which still explains ADC Filter options, which are no longer there and add the information open9x always uses OSMP option as explained in er9x. I used in former times (last year) also er9x and choose that option, so I am very happy with this decision you did. I look forward for the next version of open9x, especially the backlight dimm option, hopefully included. Great work, please continue. Btw, I thought I found a donation button, but can't find them anymore, where is it?

Right I asked to make donations to MSF. But it's true that now I need to buy some sensors, so a donation will be welcome ;) You will find a link in companion9x help dialog.

Done, hopefully worked and helps you to buy whatever needed to continue. Please do not forget stock configuration in future. Thanks again and please continue...
