sound comes out in chunks about esp-radio

It looks like you have the diodes mounted in reverse.
For testing you could do without the reset circuit.
First step is to get rid of the error messages. Are you sure that the GND of the VS1053 is tightly connected to the GND of the ESP?

While not playing, ringbuf 0, stream 0 is okay (no streem, nothing buffered).
During playing the ringbuf is mostly filled up to 20000 bytes and the stream should also have some bytes in it.

Hi Ed, i got rid of some errors; Slow SPI is working, but the Fast SPI test still fails as below
CPU is set to 160MHz, not sure where the speed issue comes from. the ESP-12 that i am using is quite old, maybe a hardware issue, i'll buy a new one to try. or any other ideas?
Thanks a lot- Tom

Looks like an SPI problem.
Did you check the ground connections?
You may try to run the ESP on 80 MHz, change line 1382 to:
system_update_cpu_freq ( 80 ) ; // Set to 80/160 MHz.
You may also try to disconnect the TFT display, it shares the SPI bus and maybe there is something wrong there.

Hi Ed,
It seems i have identified the cause of the problem: the VS1053 i am using is an Arduino shield, with a SD card, and when an SD card is inserted, it interferes with the SPI. As soon as i unplug the SD card, it works without a glitch! I tried pulling the chip select of the SD card high but that does not solve it. Maybe you have any ideas?
Thanks a lot for this great project.

[Edzelf]

Yes, that makes sense. Maybe you can find out what GPIO is used for the SD card and then redefine the pins used in the project.
Have you noticed the new version of Esp_radio (with MQTT and new configuration setup)?

[tomtobback]

hi Ed, all working fine now with the new version, without display, one button on GPIO0 for next station. It seems the next station function does not check for the number of defined stations so it just keeps going up, trying even when there's no presets - is this easy to fix?
Another note; the code as GPIO0 as INPUT_PULLUP so the 10K resistor in the schematics is not necessary, right?
And in the VS1053.begin, the test for slow SPI says 2MHz in the comments but the number is 200,000 so that is rather 200kHz, right?

[Edzelf]

tomtobback:
1 - Will return to preset 0 now after highest preset.
2 - Pull-up not necessary (but doesn't harm).
3- Slow SPI test is at 200 kHz indeed.

Current version has some loose ends, as I am trying to make uploads more stable and I am busy to support stand-alone mp3 files.
