Is it possible to connect Core2 to an external speaker or amp?
I found out some people are going for Pin 25 / Pin 26 and ground on the M5STACK BASIC but what about the CORE2?
I tried those pins, but doesn't seem to work.
I am sure someone must have solved this problem. Is there sth. I need to set up beforehand in UIFLOW?

Hey there, I recently made a purchase of the atom speaker kit. However I cannot find the module in UIFlow.
Can I make it work there or is it Arduino only??

@ajb2k3 ok, I see. But thanks for your reply. I post in this forum if I can figure it out

@ajb2k3 thanks for your reply. Yeah, I figured out the same thing with the file path on the core2 and it plays wavs quite reliably through the speaker.... however, this speaker is quite low volume and in my setup it has to give voice commands to an ipad (in an art exhibition)... so I need to connect to an external speaker.

Do you happen to know how I can route the wav-audio to the DAC (pin 25) on the core2?

I tried with the wav player template by @lukasmaximus or @lukasmaximus89 ... but the result is that the firmware of core2 doesn't seem to know the I2S modes...

any suggestions what to do?

@ajb2k3 Yes, I updated to the latest firmware.
I know, it's an old topic, but I made a new one, about playing audio to external speakers but nobody replied :(
So I am trying to figure what people did before me.

@lukasmaximus Hey lukas, on which firmware version did you make this run?

I am running it on a M5Core Basic and the unit reboots after the .wav was played once and I hit the button again.

I have to uncomment:
uos.sdconfig(uos.SDMODE_SPI,clk=18,mosi=23,miso=19,cs=4)

to avoid another error

still I get the:
"sd card not mounted" lcd print.

Is there any chance to adapt this patch to a newer firmware version?

I have also tried it on a Core2, but it doesn't seem to know any of the I2C modes which you defined.

would be great to get this to work again and make/update custom uiflow blocks.

Thanks in advance for your reply

has anyone tried to run this on a core2 ?

I get errors when trying to initialize i2s device:

"type object 'I2S' has no attribute MODE:MASTER....

Yeah, I just implemented a communication via the espnow broadcast block.
Works ok, as long as the messages don't overlap.
somehow I cannot get IDed messages to work.
Have you ever succeeded with that?

I have the same problem with my Core2. Followed the demo in every step. And I am using the latest version (beta web) and newest firmware.
Could you please send me the m5f, too?

I can't find the "P2P Read" and "P2P Send" Blocks in UiFlow for Core2.
They don't exist?
What is the most stable and fastest way to make two units talk to each other?
(in my case M5GO inside a MyCobot Pro & Core2)
thx for any ideas
