    maxpenna got a reaction from bluehash in Aida DSP Boosterpack   
    Hi everyone,
     
    a lot of time since my last post on this forum
    and noticed many things has changed, in better.
     
    I want to spread (spam) my boosterpack project,
    Aida DSP boosterpack
     
    It's a boosterpack dedicated for audio and for now available only for TivaC.
    With this boosterpack you can do 24bit/192kHz pristine audio elaboration,
    since it has a DSP on it, so while this DSP is occupied with audio elaboration
    you can do a lot of things with your mcu: read audio signal envelope, manage a user
    interface and -why not?- a complete keyboard or a rich display, ecc.
     
    http://www.aidadsp.com
     
    Libraries are available both for Energia and Arduino, please note that I hacked
    wire.cpp and wire.h a bit to get things done.
    You can buy the board, on our store to start focus on your audio application.
     
    Suggestions and collaborations welcomed!!!

    maxpenna got a reaction from Tails86 in Flashing the missing DCO calibration constants   
    Ok, I've made
     
    this simple program to see on P1.4 SMCLK with a probe oscilloscope.
     
    SMCLK sources from MCLK with no prescaler.
     
    On P1.4 I've outputted SMCLK with 8 prescaler, for usage with common oscilloscopes.
     
    Launch the program you see the clock step change rising in frequency from default (1.2Mhz?)
     
    to 1MHz to 16MHz.
     
    I've checked with my oscilloscope the last frequency and it's correct (2Mhz * 8 = 16Mhz). I think the whole program
     
    works.
     
    NOTE: small and unimportant bug on dco_calibration, change if(!chk_data()) statement on line 88
    with if(chk_data()) so you can see green led blinking if it's all ok.
     
    Thanks

    Hi everyone,
     
    I've added the checksum for proper verification of the data inside flash.
     
    I've also regrouped code some parts in functions.
     
    Finally, this version works with TI DCO calibration example in C (MSP430G2231 code examples), because I really don't understand asm.
     
    Is there some specific reason you used asm routine for DCO calibration?
     
    The attachment is the project in CCS4.
     
    Thank you all, comments appreciated
