Nothing has changed; I need to stop the IRQ, otherwise the system will crash and restart.

Hi Ben

Perfect! It's working nice.
Normal working, the current from the Board is 61.8mA
The deepsleep current goes down to1.6mA and to 0.3mA (300uA) with shutdown the ADC.
Soon I include a LDO to turn off Analog part and and then I expect less than 200 μA

One more little thing.
Before I set the ...

Hi Ben

The MCP356x1 is a nice 24Bit Ad converter.
There is a one-channel, two-channel, and four-channel version
with SPI and many possibilities and features.
The AD converter is working perfect with FC11

But especially with battery-powered devices, which are usually most time turned off, the Full ...

Hi to All

I ran a test on Ben's board and used the loop to initialize the card every 10ms .
I didn't use an SD card, but I checked it with the KO, and the signal was perfect.
Then I switched the clock to a free port (GPIO 19 and GPIO 20), and the clock was perfect there, too.

I added the same ...

Hi to All

There is one remaining issue that I have not yet been able to identify or resolve.

The FC11 fails to initialize the SD card on this board.
However, the same SD card operates reliably with FC11 on other board, such as ESP32-S3 and ESP32-WROOM boards.

Interestingly, similar issues can ...

Hi Martin

That's interesting what you're doing.
I'm also trying to put an S3 into deep sleep right now
I'm guessing the name “Zero” comes from Waveshare.

Yes, depending on how the USB connection is used, you may need to manually put the board into bootloader mode. To do this, press and hold the ...

Hi Ben

The SD card works with the old SD component, but I don't have any free SPI buses left because of the display and the AD converter.

I'm having trouble with the C code insert from You.

Does it just need to be in a C code component, or should it be added as a supplementary C code?

Hi Lian

I started with a 10-meter test, and it worked without any problems.
For longer distances, I have to go outside.

Hi Lian, Hello everyone

Sending with the ESP32-S3 worked right away.
I just used the macro and added the Wi-Fi

I don't think this easy way is available for the WEB App....

Later, I'll also test the Wi-Fi range

Hi Lian, Hello everyone

I wrote a simple server and client program to send data from one Flowcode program to another Flowcode program .
It works with strings and byte arrays.
Maybe it will also work with an ESP32 over Wi-Fi.
