Re: Demo: I2S sound output and MP3 decoding in an ESP8266

I've tried it out on and ESP-01 and an ESP-12, without extra SRAM and with the PWM hack.

On the ESP-12, it cycles maybe 20-30 times with (I think) watchdog timer resets before settling down to work properly. With the ESP-01, I just get wdt resets forever. Does anyone else get this? Can I, and should I, make the watchdog timer longer to give it a wee bit more time? If so, how? Why would it be different between ESP-01 and ESP-12?

My power supply is OK.

...looking on ebay for an mp3 decoder chip for an ESP8266 project I have in mind, I came across this:

http://www.ebay.com/itm/GPD2846A-TF-Car ... 5679c05e2d

...and says it uses a GPD2846A chip. Its got a slot for a TC card, and is extremely cheep. After looking around on the web, there is almost no information on it. Any ideas? Has anyone used it?

Probably same chip used in the following :
