If I plug the Hyperpixel 4 on top of the AroioDAC it will work but if I connect the display with a cable, after the boot the Volumio UI flashes shortly (show album artwork play buttons, etc.) and it become black after half a second.
Could this be a power consumption issue? Has a 15cm cable so much impact on this? Does the display has an own power connector?
Sorry but I’m newbie. I understand, messing up the GPIO is not a good idea. But it works if I place it directly on the GPIO on top of the AroioDAC but not if I use a cable between the AroioDAC and the display. So there is no conflict with the boards and data. Also it works for a second after booting Volumio. It shows the correct screen for just one second. So what do you mean with messing up the I2S in this case?
Ok, than I can put the display in the trash. This is a pity. This was the third display I tested and the best one. Any suggestions? Alternative displays?
In the product description is mentioned an alternate I2C interface. Could this help?
I want to build my own streaming amplifier like Cambridge Audio EVO. For this touch is only optional. I don’t need touch because I want to control the streamer from my couch. I build my own case and the display should not have more than 4inch and not below 2.8inch.
I like the high resolution and quality of the hyperpixel. Also the pimeroni square displays looks very interesting. It’s a pity that they wont work.
I think HDMI will be the easiest option but it need an extra USB connection and I want to have acces to the connections of the PI from outside the case. I’m currently thinking about a DSI display but don’t know if drivers could be a problem with Volumio.
Thanks for your help.
To be honest, I‘m more looking more on the High end side, with own clock (Reclocker), clean linear power, based on Boards from Ian Canada. Currently I’m starting cheaper with the AroioDAC (from a German high end manufacturer). This board has own clock, one for 44,1kHz multiplier and one for 48kHz multiplier. This allows me to collect experiences, because the trouble with the display shows me the problems. The display should be kept while the DAC and Amplifier grows. The milling of the front is more expensive than my complete current test stage, so I don‘t want to change the display later.
OK, fair enough. The only Pi I currently play music on is a Pirate Radio based on the pHat Beat and just streams Classic Rock from the Internet. No display on that one. Very basic simple operation, just some buttons for volume up down etc.
I do have a Pirate Audio Speaker on my itty bitty beat box. Display isn’t used though, its just something for my grand daughter to have fun with playing drum and piano sounds.
Finally. I appreciate your help, thanks. I’m sorry, but for now I found another solution. The DSI display I selected now works like I want. Perhaps in the future the Hyperpixel will also get an DSI connector. But for now…
