Re: TI PCM1808 as audio input

I dont know where to report this, but the library PIGPIO http://abyz.me.uk/rpi/pigpio/ breaks something WLAN related on my Raspberry PI 3B+. It still says it is connected and everything, but I can't even ping the PI. The only thing i tried with it was to change the clocks for GPCLK0 and GPCLK2 with ...

Re: TI PCM1808 as audio input

Thanks for the effort explaining everything. Right now I am at a point where I dont want to see it anymore. I did some more research and I tried http://abyz.me.uk/rpi/pigpio/pigs.html the clock (hc) on GPCLK0 and GPCLK2. I tried to build a clock with a crystal oszillator. I tried every combination o...

Re: TI PCM1808 as audio input

Thank you so much for explaining. I know I might sound like a complete noob, but that's the reason I bought a breakout board... to not have to deal with the magic stuff real engineers have to deal with. One more question: There are quartz oszillators with 4 pins (N/C or Tri-state, GND, Output, +VDD)...

Re: TI PCM1808 as audio input

Hello, Thanks for your reply. I dont really care if it is master or slave, if at the end it works as an audio input. I just thought it might be easier for testing when it is configured as slave, and i even soldered jumpers on my testing perfboard to change FMT, MD0 and MD1. So changing it to master ...

TI PCM1808 as audio input

Hello, I recently bought a breakout board for the PCM1808, and tried to hook it up. There are not many resources where you can get informations about this chip or how I2S works with the PI. The board is the same as here: https://www.ebay.com/itm/24Bit-Amplifier-PCM1808-Audio-Stereo-ADC-Single-End-An...

Re: XDMX - Raspberry PI 3B+ Dualscreen

Hello, Here is a little update on this topic. I came up with the great idea, that I could simply make a VPN connection on the USB network bridge to compress the data from xdmx, and fight the network bottleneck with CPU power. So I installed OpenVPN on raspberry and banana, broke the network manager ...

Re: XDMX - Raspberry PI 3B+ Dualscreen

Thank you, I definitely like the idea. I just dont like that it is LVDS, I like to have HDMI for my project. 18 bit color is more than enough in my opinion, I even tried to go down to 16 bit to speed XDMX up, unfortunately i did no get it running below 24 bit. But that looks like a cool and interest...

XDMX - Raspberry PI 3B+ Dualscreen

Hello, I am looking for a Dualscreen solution for 2x 1080p monitors. I know the Hardware is pretty limited on the PI and it would be easier to just use a PC with a graphicscard with multiple outputs. Well... I have a Computer, but i like to tinker a bit and get it working with the PI. In my search f...
