prerequisites: You must have a H3 SbC with HDMI and rca out. Orangepi PC for example. processor : H3 Linux distro : Armbian Image of Armbian to get working : Retrorangepi ([login to view URL]) Image flash to micro-SD Using a H3 SbC (orangepi, banana pi, nanopi...) with Retrorangepi, we want an automatic switch of display between an HDMI screen and RCA Video/Audio when HDMI cable is connected/unconnected to the SbC: - When HDMI is NOT connected : display on the RCA LCD and audio to RCA output. And stop HDMI output - When HDMI is connected : display on HDMI screen. And stop RCA Video/audio Currently it is possible to switch between HDMI and TVoutput from software by going to retrorangepi menu and launching a script manually. (link to this script github : [login to view URL]). Then the SbC has to be rebooted, then boot on the specified output. Aim of the project : Plan A (prefered option) : - By default, if HDMI connected SbC boot on HDMI. - If HDMI not detected then boot on RCA. - While the SbC is ON, if HDMI is plugged in, display switch from RCA to HDMI - While the SbC is ON, if HDMI is unconnected, display switch from HDMI to RCA Plan B : - Both outputs (HDMI and RCA audio/video) are enabled at the same time, with no artifacts and both working correctly. Plan C (minimal): - By default, if HDMI connected SbC boot on HDMI. - If HDMI not detected then boot on RCA. Not sure Plan A is possible. If it is not possible please repport why before going for plan B or C. From H3 specs it should be possible to enable both HDMI and RCA at the same time, however no one could get them to work at the same time (without artifacts on displays) so far. (Display settings are set in the [login to view URL] in the root of the SD card. (To open [login to view URL] you can use bin2fex and fex2bin tool preinstalled on armbian.)) This link might help: [login to view URL] Plan C is minimal accepted result. What is expected : - This should not have an impact on SbC performances (should not use constantly 30% of CPU...) - Video of the system setup, showing the SbC behaving as expected on Retrorangepi. - All necessary drivers/files/settings. - Explanation of how it works and how to implement the solution. Please give me estimated timeframe. Thanks

Hi I'm an electronic engineer with more than 5 years of experience in Embedded systems designing. I have worked with single board computer for many project and much similar to this one as well. Usually I have used in built functionalities as well as GPIO in outs to connect with different functionalities. So I would say I have in depth knowledge and experience to handle this kind of project. When discussing about your project, I would say plan A is possible. But we might need to see if the OS supports any external program to any HDMI connected/unconnected information. if that is provided we can easily go for plan A. the other one is plan B of plan A is not working. I think anyhow we can switch on and off RCA output and display output. So we can keep HDMi on always and switch on and off others. We can discuss furthur about this on the chat. looking forward to hearback from you. Thank you Anusha
