@Leo05 Hi there, any updates on the PT100 support?
I'm doing POC on ESP32 and got 4 PT100 sensors working (using 4 MAX31865).
Ideally, I'd like to use a module for M5Stack.

yes i personally think you're mostly right
and, maybe you can try out PbHub to expand ports?
https://docs.m5stack.com/en/unit/pbhub_1.1

@tdahbura You cant use it on port B because the port has one hardware fixed output pin and one hardware fixed input pin.
Port C is attached to dedicated UART pins.
For port B you need the PortB version of the sensor or use a the PaHub .

can you give me some instructions how to apply the firmware update. there are no instructions. Have you try it? Is it working
Thank you

I think the MODULE_4_20MA (in the src folder) is only using some standard libraries:
From top src/MODULE_4_20MA.h:

#ifndef __MODULE_4_20MA_H #define __MODULE_4_20MA_H #include "Arduino.h" #include "Wire.h"

Try to download only the two files in the src-folder and see if you can include them into your project and compile.

Also: If you look at the code in src/MODULE_4_20MA.cpp you'll see that they include some register addresses, maybe that is required for this AIN4-20mA unit?

@scaramanga have you checked the product listing and documents on the M5Stavk website?

@dnd3ch Most Unit style sensors have a compatibility section, down at the bottom of the sensor's document page:
https://docs.m5stack.com/en/unit/DLight Unit
Go down to the FAQ section near the bottom.

Having said that:
All of the unit sensors will work with any M5Stack controller.
The Dial is just a StampS3 for example.

The M5 core bases are another story and require research or asking here if they are compatible.

@usYmat Yes. I am using it to connect to an Android app over BLE. You can look up sampel code for ESP32 for Bluetooth pairing to a device. Seems to work ok.

@sebhuet
From the schematic it looks like this is a common IR, so you just need to find the right size.

@kuriko
Indeed a strange situation.
It occurs if I use TX=26 and RX=32 and also TX=22 and RX=19 to initiate the can BUS on a M5Atom
ESP32Can.CANInit(); // Init CAN Module. 初始化Can

If i dont initiate WifI I can send data through the CAN BUS. The moment I initiate WiFi, no data come through in the CAN BUS.

I will do some other trials with other devices (M5Core 2 and M5Atom S3) to check if it is a hardware problem.

I do hope to get this solved because if this problem is definite it means the Communication abilites of the CAN bus are limited.
Regards

(* Oh, important : When using WiFi i do receive CAN BUS messages , so that is weird, i really need to dive into this*)

Hello @Steven010

have you tried to follow the examples given in the documents listed here?

From what I can tell your modem is connected to LTE-M1 but with AT+CIICR (a command that doesn't exist for SIM7080G) you try to setup GPRS which doesn't match LTE.

Have a look at for instance the document explaining a TCP/UDP connection. I think your next command should probably be AT+CNACT=0,1 to activate a PDP and then AT+CNACT? to check for an IP address. And then go from there.

Thanks
Felix

Sad to still see no StampC3 support in uiflow. The risc-v and C3 support in micropython has been around for quite some time, and other C3 boards are in there now.

Thanks everyone!

Hello @gohan_oishii

GPIO3 on the ESP32S3 is a strapping pin (see here) and is pulled up via external 10 k resistor (see schematic here).

Thanks
Felix

Hello @pos3tap

hmm, works for me in UIFlow2. Please see example in Project Zone: M5Dial_RFID_Touch_Test_UIFlow2.1.5

Thanks
Felix

I should have said I am concerned about the form factor, since the 18650C holds the M5Stick INSIDE its case.

I checked the size of each M5Stick product and they are the same size i.e.
Product Size 48.225.513.7mm.

So the answer should be yes.

Thanks anyhow, ajb2k3.
