Flowcode Support Board

Hi to All

One more question. With purchased hardware with an ESP32-S3, I have to press the reset button for 5 seconds to flash the firmware.
Then press the reset button again.
The programme runs.
Now I want a connection with the USB C connector to the computer.
A serial device com15 and also an USB jtag/serial debug unit appear in the device manager of the computer.

but I can't make a connection with the App Developper with Com 15
and I don't have a pin for the interface in the firmware either.

Is this connection possible with USB component ?

I think you will need to use the Serial Port component and not the USB component.

Hi Steve

I suspect it's not that simple.
The USB pins go directly to the ESP32 C3. So I can't use an Rx/TX pin. Many ESP32 boards have a USB driver that goes from the USB connector to the UART pin.

What about BLE Uart? Is BLE already possible to test?

Sorry, I'm not familiar with that device. You should be able to communicate to COM15 from a PC Developer app using a Serial Port component. But I don't know how you would access the same serial connection from within Embedded code in the device itself.

Please can you send us a link to the specific board you're using.

Looks for devices like this to do comms back to the PC would require a USB component. Might not be too hard thanks to the IDF so I'll get it on the list.

Demo with display (working in SPI softwaremode)

That looks great, are you able to program the screen? Do we need a new component for it?

I've just bought myself one and also got a couple more M5 boards. Unfortunatley they look like they might take a while to get here.

Hi Ben

For the Atom S3 the component gLCD_ST7789V1 is working to display text.

The Atom matrix has a 5x5 LED Matrix and it's working with FC WS2812C

For the M5 Dial knob I think an additional component for GC9A01A Display driver is necessary.
The display is also used by other manufacturers

A very good feature of these M5 stack modules is that the IMU MPU6886 is supported von FC

Hello,

My M5Stack parts have arrived and I've now added a new component for the GC9A01A Display driver. Seems to be working well for me but let me know if you give it a go.

I've added in a few new targets to the ESP Misc section too, should hopefully make things with the M5Stacks a little easier to get started.

Hi Ben
Thank you very much.
The Atom S3 template is working nice.
the display also works,
but I have to set all the pin.maybe you can make a template with a display
Display only in software mode on my computer is compiling.

a new component is SerialPort.fcpx but no info what it is.

and the display makes an offset. i was able to set and correct this with the other driver Set the pin:
