Using an ESP8266 to playback an audio stream over WiFi and 7-bit PWM.

esp8266_wlan_speaker's Issues

Remove _V7

Could you remove the version from the end of the INO file name?

Is not good for the IDE and prevents change tracking.

Is a higher bitrate possible?

Nice project! I was wondering whether an ESP8266 would be up to this job, and came across your work. Personally, I'd like to get some higher quality. For this, I'm thinking to use a PT8211 DAC, which should give much better quality, while it is still really cheap.

However, I note that you set bitrate to 33kps, specifically, and I can only guess that you hit some limit at this point. Is that correct? Do you have any insights on where the bottleneck is at? Is it:

1. the I2S bus itself
2. the CPU load for PWM coding
3. the networking?

For 1) and 2), using an external DAC should allow me to get around the limit, easily. For 3) it would be a different story.

Thanks!

can I change it to 14 bits PWM??

can i change it to 14 bits PWM?? because in esp8266 there is 14 bits PWM.

Suggestion

it would be nice to have it paired with an esp that reads the audio via ADC and send the data to the speaker
just an idea
still, nice project!

Pinout caution

I believe the ESP8266 can't be programmed if the D8 pin used for AMP_ENABLE_PIN (GPIO15) is held high, which I found occurred when I connected an OTS relay module to it.
Just something to keep in mind.

Where to stream music from

when you say call "avconv -i gong.mp3 -f s32be -acodec pcm_u8 -ac 1 -ar 33000 tcp://192.168.1.100:5522"
How do i do that? how do i stream sound to the esp?
