try reset it several times

EZData is under maintenance and will be offline for a while.

Hello @daniel-edge456

in UIFlow2 v2.2.6 using touch blocks for M5Paper and then look into the Python tab I get the following code to get touch coordinates:

if (M5.Touch.getCount()) > 0:
  x = M5.Touch.getX()
  y = M5.Touch.getY()

doing the same with power blocks I get:

Power.deepSleep(1000, True)

to put M5Paper into deep sleep.

Thanks
Felix

Hello @huanfai

looking at the soucre code for UIFlow2 device firmware I think authentication keys are fixed to default values. See here and here.

In ohter words I don't think the RFID blocks in UIFlow2 can handle anything different than default authentication keys.

Thanks
Felix

@robski @ajb2k3
Thank you for your answers.

I reinstalled M5Burner...

But when I went to the online UIFlow 2.0 application, I realized that, like an idiot, I was using my username instead of my email address to log in.

Now everything works normally. 🙂

Sorry for the blunder... but I'm guessing I'm not the last person this will happen to 😁

Cheers,
Steph

ROFL,
I think most of us have done that at some point!

Hello @oracle_sod

ok, I see, the DFRobot version has an UART interface. M5ExtIO2 GPIOs can be set to multiple modes (input, output, ADC, servo, neopixel and PWM) but I am afraid none of these modes can be used for an UART connection.

According to the wiki page RX is used to select the mode, this could be achieved via M5ExtIO GPIO set as output.

However the TX line sends data with 9600 Baud, which I doubt M5ExtIO2 can handle.

That said, what is the reason you don't connect all three Ultrasound units directly to the M5Core? That would require 6 GPIOs.

And if you could live with the fact that all three Ultrasound units use the same mode you could get away with only 4 GPIOs, 1 GPIO to select the mode for all three units, and 1 GPIO for each unit to receive the UART data.

Thanks
Felix

@m1cr0lab try deleting M5burner and reinstalling, failing that it could be an issue with the server

@zakk3456 doesn’t need to be selected from the device software list?

@Shanks-0
Port B is generally a no as one of the pins is normally input only
