Well, it's working. The path to my Windows profile has a space in it. I created a local account without a space, and my empty program compiled with no issues. Don't know if that's the reason. Very strange. Makes me want to reinstall Ubuntu, or something. Thanks for the replies, Terry.

Hi @felmue and thanks for the help. I changed GPIO and it works now. Strange as input port 2 worked when the temperature sensor were implemented separably. However I have spend enough time trying to make it work. So I will not conplain now that it is working. Thanks again

My board was defect, I changed the MotionBase , now it is working perfectly.

Unfortunately not. Arduino work on a lower level than MicroPython and so runs directly on the hardware. Micropython is an interpreted language and so need to install a boot loader/ interpreter to run. It can be inconvenient to have to install the MP boot loader when you want to switch back but its now a simple process.

@felmue said in Stamp Pico USB Serial: Or in other words, there is no way to directly connect D- and D+ from the USB-C breakout to the M5PicoStamp. Hi Felix, thanks alot for that information. Was hoping this converter could be easy be done by some ICs and restistors maybe but would be too difficult for me yet. So i think i will get another controller with built in or a cojntroller with onboard USBC connection. Makes no sense to spend much time and money if the device will be procudes 100 times each with MCU and a serial converter. Your help was great!!! Best regards Hannes

@tobias-h said in UHF RFID Unit (JRD-4035) on Arduino Uno: E.g. what board to select in the board manager ? In the Arduino IDE select: Tools - Board - Arduino AVR Boards - Arduino Uno. May I suggest you first get more familiar with the Arduino IDE, your Arduino Uno board and some simpler sketch examples for the Arduino Uno? Then maybe do some experiments with the serial connection (which is needed to talk to the UHF RFID Unit)? Alternatively you can always get an M5Stack device for which the example has been written. Thanks Felix

@m5stack How can I get bin file from the device?

There is aM5StickPlus library !! Thanks a lot!

Got it! Thank you!

Hi Just add HardwareSerial Serial2(2); under #include <Arduino.h> in /Users/matthias/Documents/Arduino/libraries/M5Stack/src/LoRaWan.h

So, I have 2 m5stack core with me. My idea is to have these 2(or potentially more) to communicate with each other via LoRa, one to be a sensor node, and another acts as a receiver. The receiving node will then upload the data received from the sensing node to thingspeak. The components used in this system is the ENV sensor, and the LoRa modules. I hope this explains what I am trying to do.

most M5Stack Arduino API , you can find it from this page. link:https://docs.m5stack.com/#/en/arduino/arduino_api
