You can try turn off system proxy or VPN if has any, or change a network.

The default internal I2C scanner of Tab5 in UiFlow2 has bug, we are now fixing it!

Hello @BruderTom

the issue seems to be an I2C conflict. Internal I2C already uses Wire1; the PPS code initializes a second I2C instance (Wire) with the same GPIOs for SDA and SCL. The result is: both I2C instances (Wire and Wire1) fight against each other.

Try replacing below line so the correct Wire1 instance is used for PPS as well:

//  while (!pps.begin(&Wire, M5.In_I2C.getSDA(), M5.In_I2C.getSCL(), MODULE_POWER_ADDR, 1000000U));
  while (!pps.begin((M5.In_I2C.getPort() == I2C_NUM_1) ? &Wire1 : &Wire, M5.In_I2C.getSDA(), M5.In_I2C.getSCL(), MODULE_POWER_ADDR, 1000000U));

Thanks

Hello @BR123456

it looks like the internal scan in UIFlow 2.3.8 default scanner is broken - I do not get any results either.

However if I scan the internal bus via I2C blocks it picks up all internal I2C addresses and what's connected to the M-Bus. The example is called M5Tab5_I2C_Scan_Test_UIFlow2.3.8 and you can find it in the UIFlow2 Project Zone.

Hello @paulgrevink

have you tried to disconnect everything from M5StickCPlus2 and fully powering it off by pressing and holding the power button?

Also have you tried to erase flash using M5Burner before installing UIFlow2 firmware?

BTW: I did a test and installed ESPHome basic firmware, then installed UIFlow2.3.8 firmware and then ran M5StickCPlus2_GPIO32_GPIO33_ON_OFF_UiFlow2.2.0 from Project Zone without issue, e.g GPIO32 and GPIO33 toggle just fine between 0 V and 3.3 V.

Note: While ESPHome was installed GPIO32 measured something like 0.2 V.

Thanks

Hi guys

yes, it looks like there was a display / touch related change. See Screen Driver Change note here.

My guess would be that this change has not yet fully been integrated into UIFlow2.

Thanks

Hello @Rusticus42

there is a solution: use a M5PbHub unit (which is an I2C unit) to read the button states of the Dual Button unit.

I created an example in the UIFlow2 Project Zone: M5AtomS3_RFID_PbHub_DualButton_Test_UIFlow2.3.7

Note: I do not have an M5AtomS3R so you probably need to adapt the example.

Thanks

@tiditidi
You gotta push the download button to permanetly flash the code to the device:

Hello @Rusticus42

yes, it is possible to connect more than one I2C unit. However Dual Button unit is not an I2C unit. You can see that from the color of the connector.

• I2C units have a red connector
• I/O units have a black connector
• UART units have a blue connector

The connector on AtomS3R is white which meas it can be setup for I2C, I/O or UART mode, but only one at the time.

Thanks
Felix

What did you mean by nothing works?
