Audio Tools with AI Thinker v 2.2 A252

[SnazzyBlanket]

I am at a loss at the moment as to how to set up this board. I bought it thinking it would be easier to use only to find its a bit of a nightmare of weird versions.

using this code below I can get sound coming out BUT there is def something wrong with it (improper pin or clocking would be my guess)as it is distorted and crackly.

int freq = ((float)ptr);

}

// We want to play some notes on the AudioKit keys
void setupActions(){
// assign buttons to notes
auto act_low = AudioActions::ActiveLow;
static float note[] = {N_C3, N_D3, N_E3, N_F3, N_G3, N_A3}; // frequencies
kit.audioActions().add(kit.getKey(1), actionKeyOn, actionKeyOff, act_low, &(note[0])); // C3
kit.audioActions().add(kit.getKey(2), actionKeyOn, actionKeyOff, act_low, &(note[1])); // D3
kit.audioActions().add(kit.getKey(3), actionKeyOn, actionKeyOff, act_low, &(note[2])); // E3

void setup() {

AudioLogger::instance().begin(Serial,AudioLogger::Info);

// Setup output
auto cfg = kit.defaultConfig(TX_MODE);
cfg.sd_active = false;
kit.begin(cfg);
kit.setVolume(50);

// Setup sound generation based on AudioKit settins
in.begin(cfg);

// activate keys
setupActions();

}

// copy the data
void loop() {
copier.copy();
kit.processActions();
}`

I also tried the other driver options but this was the only one that gave any sound at all

THANKS for any help

Serial output is slow and therefore can have an impact on audio: This is described in multiple places in the documentation!
So just switch the logging to warning (by using AudioLogger::Info) or lower the sample rate( cfg.sample_rate = 22050;).

Ahh I was so focused on it possibly being one of the AI thinker boards with issues I did not even think to switch to warning or error (which I have read about before )thanks Sent from my iPhoneOn Mar 7, 2024, at 10:22 AM, Phil Schatzmann ***@***.***> wrote: https://github.com/pschatzmann/arduino-audio-tools/wiki/It's-not-working —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>
