      Thank you for sharing this easy solution that instantly solved my problems with starting up the CS42448 outputs, both at power on and after compiling the sketch. "What monkey sees, monkey can do." 😎

      TheHermit reacted to M4ngu's post in the thread Quad channel output on Teensy 3.6 with Like Like.
      for me it worked like this: bool AudioControlCS42448::enable(void) { Wire.begin(); // TODO: wait for reset signal high?? if (!write(CS42448_Power_Control, 0xFF)) return false; // power down if (!write(CS42448_Functional_Mode, default_config...

      Here's a slightly long-winded demo of the use of new to create the TDM objects after the CS42448 has been initialised: #include <Audio.h> // define this macro to use the "normal" // statically-created objects //#define USE_STATIC // GUItool...

      Thank you, Paul. The only change I've made to your OSHpark PCB is the removal of the header to stack 2 boards. Prior to finalizing my PCB design, I had previously asked about the purpose of the CAT811T and it was explained that it was required to...

      Thank you for posting this. I've basically copied the OSHpark CS42448 PCB (which was working ok) into my project's PCB, with 6 output channels + op amps. The CS42448 never works @ power up and only produces static negative offsets in the...

      CS42448 magic bit I was looking at this, and scanned the CS42448 data sheet to see if there might be a clue in there ... and maybe there is (DS648F5 page 28, Figure 12): I read this as saying that the internal registers should be set up prior...

      No worries, it’s not just “my” thread … I was rather enjoying it TBH. I’m sure I’d‘ve objected if it’d got really silly, and it’s fun to bump threads when they’ve gone a bit Moribund the Bürgermeister for a while…

      Hi, I'm hoping to migrate from the soon to be obsolete CS42448 CODEX to the PCM3168A for my T4 Laser Synth project, which brought me to your github repo. But, only found your library files. Have you had any success with getting the PCM3168A up...

      Hi hakon, I'm very interested to PCM3168 schematic. First I would like to know if iit is correct. Has someone used it to make a well running PCB ? If so, could someone resend a copy of this schematic? The one I have has bad resolution and is...

      Hi Hakon, Having successfully hand soldered my prototype PCB, based upon Paul's OSHpark PCB & the soon to be discontinued CS42448, I'm also hoping to migrate to the PCM3168A CODEC and seeking guidance, which led me to your post. Have you made any...

      The PCM3168A from TI looks pretty snazzy, but no idea if anyone has tried it with a Teensy.
    • TheHermit
      Yeah, I wish my one head were even 1/2 that hoopy, but nah. To clarify, those prices were for the complete projectors, no just just the scan fail circuits. BTW, the CS42448 is still available, but is on the 'to be discontinued' chopping block's...

      Just confirmed that Audacity can convert between wav and aiff formats. So, I'm all in..... except for one reservation. Class 4 show lasers can be dangerous, if static. What would the chances be of something like that happening during 6 channel...
    • TheHermit
      Thanks for the quick reply & link. Unfortunately, aiff is the format that ILD Render outputs, other than ILD (International Laser Display) format. 5 channel is a laser industry kinda thing, but my T4 Laser Synth can use all 6 ADC/DAC channels. As...

      Hi Folks I've just completed the PCB of my T4 Laser Synth, which simultaneously uses the Audio Library's synth waveforms *28 , mixed/multiplied down to 5 (XYRGB) channels, playable via MIDI surface & Reaper's DAW, which is working great, btw...
