It may have the SSD1306 chip, try this library to talk to your display: https://github.com/gadjet/1602-OLED-Arduino-Library Regards, Vinc

@Aapje Thanks for sharing the info. If it's free programmable it may be used to easily control the user interface of DCS and save key commands of the HOTAS controllers, like center TrackIR or VR-Headsets. Regards, Vinc

Hi there, you may try this snippet for lc2 void onUhfFreqDispChange(char* newValue) { lc2.setChar(0,0,newValue[0],false); // digit 1 lc2.setChar(0,1,newValue[1],false); // digit 2 lc2.setChar(0,2,newValue[2],true); // digit 3 with dot lc2.setChar(0,3,newValue[4],false); // digit 4 lc2.setChar(0,4,newValue[5],false); // digit 5 lc2.setChar(0,5,newValue[6],false); // digit 6 } DcsBios::StringBuffer<7> uhfFreqDispBuffer(0x45b2, onUhfFreqDispChange); Depending on the order of your LEDs, you may swap the digits (newValue[0] to [6]). Element 4 of the string (newValue[3]) is a dot and not a number, additionally the "true" on digit 3 than may be shifted to digit 4. As the radio display code seems to be similar to that of the A-10, you also may adapt that of my OLED displays. For the F16 you use the "UHF Manual Frequency Display" and "UHF CHAN Display" code snippets. Regards, Vinc

Many thanks for your efforts. Will the Preschen air base from former East Germany be included? It was home of Fighter Squadron No 3, including two MiG-29 ant one MiG-21 wings. Thanks in advance, Regards, Vinc Edit: I found it in phase 3, thanks

You can try to keep the boot button pressed during the upload process. Regards, Vinc

Did you installed the latest ESP32 drivers? I put the following lines into File -> Preferences -> Additional board managers URLs: https://dl.espressif.com/dl/package_esp32_index.json https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json Regards, Vinc

@questerymj01 You can readout the hardware SPI ports like I posted here: Regards, Vinc

As there are a few on the market, please tell us exactly what ESP32 board do you use. Probably a link to the supplier would do it. Regards, Vinc

If you still have issues to talk to the MCP23017, you may have a look how I described usage of that pin extender within my VHF FM radio panel. Btw. the tryToSendDcsBiosMessage commands can be replaced by your sendDcsBiosMessage code. Have a nice weekend, Regards, Vinc

That's a good question from the mechanical point of view. And: why always a parallel way for information (here: this forum and discord) ? Regards, Vinc

@Hammer3246 Have you already tried to declare two display objects? #include <TM1637TinyDisplay6.h> TM1637TinyDisplay6 display(4, 5);// Create a display object -> display for frequency TM1637TinyDisplay6 display2(11, 12);// Create a second display object -> display2 for channel Talk to both displays like so display.clear(); display2.clear(); The last lines of above code than must be changed in somethin like that // ---- edited code for a F-16 UHF CHAN Display display2.showNumber(digit7, false, 1, 0); display2.showNumber(digit8, false, 1, 1); // ---- end of edit Regards, Vinc

Hi Hammer, The above code doesn't include a Preset Channel display. If you want to have that display e.g. to the last two digits of an already used 8 digit module, you can plug in additional lines to my function"show_UhfFrequency()". See below code snippets for markings "edited code for a F-16 UHF CHAN Display" to see where the changes have to be in the sketch. Beware of, that I neither touched the rest of for the A-10C UHF code nor tested the edited sketch with hardware. Note, that an additional variable "String uhfChan" is created in the head of the sketch to convert the output String of the Channel to an integer and use the "showNumber" feature of the TM1637 library in the end. Regards,, Vinc

Strange! Please tell us more in detail what microcontroller and display driver are in use and if you modified the hardware. Regards, Vinc

You just deleted to much from the root sketch. Put the following line in front of the DCSBIOS_DISABLE_ SERVO definition: #define DCSBIOS_DEFAULT_SERIAL As the Serial port is used by DcsBios, you furthermore may uncomment the DEBUG definitions and Serial statements in your sketch to unblock communication.
