Re: Happy 5th anniversary everyone 大家五週年快樂

+1 here as well. I have moderated other forums as well, and I'm always happily surprised by how much of the moderation I have to do here is either 'external' stuff like banning spambots and deleting their posts, and 'accidental' stuff like people sometimes posting in the wrong forum. While on other ...

Re: i2s_adc_dac no audio output

Earphones are an inductive load, and I'm pretty sure that from an official point of view I can't advise running an unknown inductive load from the internal DACs. Unofficially (as in: as long as you don't make a commercial product out of it and complain to us if it breaks) it should be fine, at least...

Re: ESP32 VIN pin as 5V output

Yeah, chips made for 5V usually don't survive on 8V indeed. And my condolances to you wrt your wife.

Re: Issue with null key/value's when accessing a map/vector from bluetooth_callback

ex.add_func('x',callback); This calls add_func with a single 8-bit char value of 120, while add_func expects a char *pointer*. Whenever something tries to dereference this (as your print() does), it tries to read from address 120, which will lead to a crash. Try add_func("x", callback) instead.

Re: GME: IllegalInstruction

Strange. What does the crashdump look like on these devices? Any similarity, or just a crash at a random location?

Re: Obtain sender's MAC address for a UDP packet

Scott.Bonomi: You don't get the Ethernet-level packet if you use the sockets interface, which valery likely is doing. Valery: The IP you're receiving from is associated with the MAC through arp. You might be able to use the LWIP call etharp_find_addr() or etharp_get_entry() to convert the IP back to...

Re: How long does it take for uart data to be available on RX Buffer?

Because for performance reasons, the interrupt will read the entire FIFO buffer into the receive buffer, so that the hardware buffer is entirely empty to guarantee as much bytes to be received as possible before the next interrupt.

Re: GME: IllegalInstruction

Note it can also be a power supply issue sometimes. Just an extra thing to perhaps keep an eye out for.

Re: Core 0 panic'ed with initArduino()

Do you get a usable backtrace out of the crash?
