Reset Circuit with 2 Diodes not working with VS1053b? #200

First, thank you for this great Project.

I build my WebRadio without Display and 3 Button usage on GPIO2, GPIO15, GPIO0 The both Diodes from VS1053B-Reset to GND Result to a not working VS1053b

Set the VS1053b-Reset up to 5V by a 10K Resistor an all working well.

Is this a bug in the circuit? Or why this not working if the Diodes connected to GND?

Check your wiring again. XRST with 1k pull down to GND, and the two diodes connect to GPIO 16 & GPIO 5.

The diodes acted as OR gate. During normal operations, XCS and/or XDCS will be high, so XRST will always high. The only time goes low is when XCS & XDCS goes low during init (line 575-577)

BTW, if I am not mistaken VS1053B is a 3.3V part, pull up to 5V might damage it in the long run.
