    16 bit DAC with a clock signal

    yeah I may give it a go using a i2S port thanks :)

    16 bit DAC with a clock signal

    I got it working :) CODE] for (int i = 0; i < 16; i++) { digitalWrite(Out1, (D1 >> (15 - i)) & 0x01); digitalWrite(Clock1, HIGH); digitalWrite(Clock1, LOW); } digitalWrite( Latch, LOW); digitalWrite(Clock1, HIGH); digitalWrite(Clock1...

    16 bit DAC with a clock signal

    I wish to use a Teensy 4.1 and 16 bit DAC to output a control voltage, The DAC is a PCM 56 by Burr brown , I have a few of these IC's so that's the reason for using them, below is information from the data sheet. My question is what would be the best way to go about outputting the data to a pin...

    Teensy Laser Control (Obsolete thread)

    I cant get hold of those OPA188 op-amps, right now everywhere seems to have a long lead time so I cant really offer much help but I will let you know how I get on with them later on. I agree the e T4.1, is a beat and with PJRC's Audio library its super bit of kit, the reason I'm using the stm...

    Teensy Laser Control (Obsolete thread)

    Cool write up :) and nice video too, I have a Patten generator in the software that does similar things. I must say I didn't known about those OPA188 op-amp, so I may have a look at getting a few, I've got hold a few ARM STM32 F030F4P6 development Boards for Ebay, They use the same MCU that the...

    Teensy Laser Control (Obsolete thread)

    Hi TheHermit so sorry for the very late reply but I've been away working and not been able to get much time online . anyway great to see your project is moving forward :) "I'm only getting the top right quadrant of the total scan range" did you fix this problem ? sounds like your missing the -...

    Thehermit... How are you getting on with this project? I'm now able to project ilda files by using laserboy to convert them to wave files first. The results are quite good.

    Teensy Laser Control (Obsolete thread)

    cool :) and yes the pixelblaze sensor board is a great little board :) I'm not going to worry about midi control at all right now as its not something I need with this project I want the unit to be totally self contained I also ready have laser show that I can run on a laptop but the whole...

    a question about reading very large files

    Thanks for taking the time to reply joepasquariello I'm using a T-4.1 and outputting the data to a SPI DAC that in turn drives a set of Galvo's, I did think about processing the data in smaller bits but wasn't to sure if the delay would show up when displayed I also wasn't to sure how to go...

    a question about reading very large files

    Hi everyone I have a a question about reading very large files, I have a simple bit of code that I modified from one of the SD card examples, it now reads a wave file rather than a text file. the problem is that the files are being read into a buffer which works fine with small files but causes...

    Teensy Laser Control (Obsolete thread)

    "So, you're using the pixelblaze sensor to digitize ILDA imagery converted to .wav" No the Pixelblaze is only used for the FFT algorithm its running, the Teensy will do everything else :).. forgive me if you already know this but your sketch wont generate an optimized signal so when running at...

    Teensy Laser Control (Obsolete thread)

    Well I've been up most of the night unable to sleep for some unknown reason ?? .... ok my amp is much more simple, its more or less the same differential amp I posted at the top of this page. I will add some voltage protection before I get the PCB printed if I ever get it that far as it may...

    Teensy Laser Control (Obsolete thread)

    Like you I used to work with Lasers bloody great beasts that needed 3 phase power and water cooling most of them where made by spectra physics and used a krypton and argon gas mix, I always wanted my own but for practical and money reasons I never got anything bigger than a 5 mW He-Ne tube, so...

    Teensy Laser Control (Obsolete thread)

    I will be very interested to see how this works. you really need your system to update the galvo and rgb DACs at the same time for the best results , will you optimize the X/Y signals before you send them to the galvo DACS ? here is a picture of what I have so far, I'm using a Pixelblaze sensor...

    Teensy Laser Control (Obsolete thread)

    " Is this not a circuit that connects to the differential inputs of a Galvo driver card" Yes that is correct, I named the jpg file Galvo driver because I have a quite a few other files that are driving other parts of my laser system and they are all at the preamp stage. Yes you could add the...

    Teensy Laser Control (Obsolete thread)

    HI TheHermit I'm looking at building a controller for my home made laser and would like to you know if you have moved forward with your project ? just in case you didn't know the signal from the controller to follow the ILDA standard it should output differential signals for the Galvo's so most...

    Chained pots have short or something

    I would disconnect a line of pots until I found the short then disconnect each pot in that line. the fact that you have soldered your wires into the wiper track holes rather than on the tabs make me think you have a few blobs of solder shorting out to the case or you have some how damaged the...
