PA Hub is a I2C expander. That means it modifies/replaces the device addresses so it can handle more devices even with the same address. To make this work the software has to decode the "new" address of the device. PB Hub is a GPIO expander. That means, it simple adds GPIO ports and convert them to one upstream I2C. As with the PA Hub the software has to decode the data. PDM microphones usually have an output which is electrical close to I2C but still different in the data part (e.g. no addressing). PA Hub is for I2C so it will not work. PB Hub may work if it is fast enough to read the clock and data and decoding the data stream on the Controller. I'm not sure if this is really fast enough.

Hi @robski, Thanks for your comment. Yes one Kmeter works alone.

Yeah, it's possible! You just need to make sure the modules use different communication protocols or assign different pins if they're both using something like SPI. The CC1101 typically uses SPI, and the PN532 can use I2C or SPI—so setting the PN532 to I2C might make things easier.

As an alternative to USB, you can program it wirelessly using an OTA (Over-The-Air) update via Wi-Fi or use an external programmer like an ESP32-based ISP to bypass the USB connection entirely.

For improved performance, use a Raspberry Pi 4 (4GB), which Robocraze sells. They are the authorized seller of Raspberry Pi Boards in India. For the last two months, I have been using this configuration without any problems. Conflicts over power or networks may be the source of your issue. Have you looked into if the M5Stack Unit V2 is using the USB excessively? Consider using a separate power source for the M5Stack or a powered USB hub.

UIFlow 2 doesn’t save BIN files in the cloud, only the project itself. The BIN file gets created when you download the project to your device (like CardPuter). If you need the BIN, you’ll have to save it manually when flashing.

@teastain looks like it is available to be used with Uiflow2 now CoreMP135 with Uiflow2

@kuriko I just got my RoverC Pro & JoyC, and two M5StickC PLUS2, and I am trying put them together. But I can't find the sample code for them (1. Rover C Pro + M5StickC PLUS2 / 2. JoyC + M5StickC PLUS2). Does it mean Rover C Pro & JoyC only work with M5StickC PLUS ?

@ewoodier84 I am using chrome, I will try a cache clear. This applies both to new button blocks and existing in all projects. Any button blocks that had buttons B or C selected have reverted to button A in all of my projects. Edit: Clearing cache did not work but on another laptop I can see all three buttons, definitely some kind of local issue.

@mohammedalmusimie have you adapted the codes to CoreS3?

@ChuckInDallas Yes.

Hello @gadgetguy I can confirm that enabling RFID prevents M5Dial from connecting to WiFi. After enabling RFID in M5Dial.begin(cfg, true, true), try M5Dial.Rfid.PCD_AntennaOff() to temporarily disable RFID while using WiFi, then after disconnecting from WiFi enable RFID again with M5Dial.Rfid.PCD_AntennaOn(). Thanks Felix

@felmue It looks like I need the binary version of getProtocolString. It seems the following is needed for sending an IRData (the mirror of what was learned from receiving.) /** * Interprets and sends a IRData structure. * @param aIRSendData The values of protocol, address, command and repeat flag are taken for sending. * @param aNumberOfRepeats Number of repeats to send after the initial data if data is no repeat. * @return 1 if data sent, 0 if no data sent (i.e. for BANG_OLUFSEN, which is currently not supported here) */ size_t IRsend::write(IRData *aIRSendData, int_fast8_t aNumberOfRepeats) And I need a way to get the IrReceiver to provide the IRData information. So It seems this is in the decodedIRData from the IrReceiver.decode call. /** * Main class for receiving IR signals */ class IRrecv { public: IRData decodedIRData; // Decoded IR data for the application } I assume I save these values with the associated functions (volume up, change channel, etc). I see that a lot of those functions are defined for various known operations, but for now I will learn from the IR receiver. Thanks for the help.

Looks like the code, with the modification you've suggested works! I can get the coordinates of the touch that lead to the wake up of the M5. Thanks!

@ajb2k3 That is what I suspected. Thank you.

@wwhite hello , i have the same problem here !! Can somebody provide the arduino source code for the folderpusher. Beside , smb protocol doesnot allow to write elsewhere than the root of the folder which is not practical I bought 3 cameras, i'm starting to be disapointed, i cannot event put a review in the store !

@ajb2k3 Batteries are plugged in and button pressed to turn BOT on and can move it around with the remote. Is there something else on the BOT to turn on other than the chrome push button? When I move the BOT blue LEDs light and when I first push the push button the while bright LEDs flash on and off.   Thanks.

I agree! USB power (5V) won’t be enough since the DC input requires at least 6V. If you’re set on using the DC port, you’d need a step-up converter. Otherwise, adding a USB connector to the wires sounds like the easier option.
