Hello @Wambo6000

maybe you are hearing what's described on the product page here: "Abnormal Device Noise".

Thanks
Felix

Hello @jhfoo2

please have a look at the UIFlow2 Project Zone example I created: M5PaperS3_Light_Sleep_Test_UIFlow2.4.3

Thanks
Felix

Hi guys

I looked at some of the comments - they are all dated from last year. I did not see anything recent. That makes me believe that the commenting feature has been turned off.

Thanks

Hello @alex9

it looks like yes, GPIO0 is TX pin for RS485. See pinmap here.

The platformio.ini example can be found here.

Running a quick search I did not find an RS485 example, sorry.

Edit: Maybe try this RS485 library.

Thanks
Felix

Hello @JohnSal

I think you only need to add one RGB unit but with number set to 6 instead of 3.

Thanks

Hello @HappyUser

just curious, which SIM module did you settle on?

Thanks
Felix

Hello @hotellonely

yes, it looks like the drop-down box needs fixing. In the mean time you can use all GPOs on the 14 pin header via some custom code blocks.

I created an example in UIFlow2 Project Zone called M5CardputerAdv_ExtPin_Test_UIFlow2.4.2

Thanks

Hi guys

I can confirm receiving IR from Unit IR is broken for M5Core2 as well.

Thanks

Hello @MitchBuckanon

like @robski mentioned, M5Dial has two ports: A and B which gives you 4 GPIOs you can use. In my test I configured the GPIOs like below:

#define ETH_PHY_CS    1
#define ETH_PHY_IRQ  -1
#define ETH_PHY_RST  -1
#define ETH_SPI_SCK  13
#define ETH_SPI_MISO 15
#define ETH_SPI_MOSI  2

Below is how I wired M5Dial to the LAN module (using a Bus Module) and some Grove/Dupont cables.

Hope this helps.

Thanks
Felix

Hello @HappyUser

ESP32P4 has 5 (five) UARTs. See here.

AFAIK all other ESP32 variants only have 3 (three) or less UARTs. (Of which the first one is used for debugging.)

Edit: ESP32S3 devices which have USB-C connected directly to the MCU (e.g. no dedicated USB-Serial chip) can use USB-C to debug (e.g. Serial) and still has 3 (three) UARTs free (e.g. Serial0, Serial1, Serial2).

Please find an example here.

BTW: are you aware of the fact that SIM76XXX is different from what is in IoT Base CatM (SIM7080G) and Atom DTU NBIoT2 (SIM7028)?

• SIM76XXX uses LTE (which is different from NBIoT or LTE-M)
• SIM7080G uses NBIoT or LTE-M
• SIM7028 uses NBIoT only

Thanks
Felix
