I have now tested the "RudderTrimDisplay". Connected are 1x MAX7219 LED display ( 8 digits ) and 2 x TM1637 LED display ( 4 digits ).
MAX7219: Display shows " 0.0". The "L" is usually only displayed after a few seconds.
TM1637: Display shows " 0.". The "0" after the comma and the "L" is missing.
When operating the rudder trim switch in the FF A320 the display of the hardware display remains at " 0.0". I see no change.
I converted Battery_1(2)_Volts, because with this parameter the correct voltage is not displayed. I tested it with the DataRefTool and looked at the values of "sim/cockpit2/electrical/battery_voltage_actual_volts". There the first two indices are used. The battery voltage in the A320 was 28.1V ( according to the display at the overhead ). The values of "sim/cockpit2/electrical/battery_voltage_actual_volts" were at 23.9V.
I wanted to test this directly again. But how can I delete the conversion of the parameters "Battery_1(2)_Volts" ? There is a function "Mark for removal", but it does not delete the conversion.
I have solved the brightness problem. I assigned all 3 displays "BRT0_Ctrl". So the brightness of the 3 displays can be adjusted. I noticed, that the brightness of the TM1637 modules is at maximum after power on, but at minimum on the MAX7219 display. Only after I turned the brightness control "BRT0_Ctrl", all displays have the same brightness.
I have downloaded the current "SimVim.dat". But after starting SimVimCockpit I have the warning " BRT_Overhead" ( The following parameter names are not recognized ). If the parameter "BRT_Overhead" does not exist anymore, please remove the corresponding entry from the A320 Layout Maps.
