Hi,
Working without problem with mysensors, I use STLink v2 from Aliexpress. LED and Button are mapped on pins 28 and 29

@mfalkvidd said in New library to read Arduino VCC supply level without resistors for battery powered sensor nodes that do not use a voltage regulator but connect directly to the batteries :

@MiKa use hwCPUVoltage() this works for AVR, SAMD and ESP8266. ESP8266 requires defining MY_SPECIAL_DEBUG though.

Thanks ! It works on SAMD21E board

It looks, its working also on NRF5 platform, tested with NRF51822 MCU

please add also "Hall efect" sensor

Hi,
pcb received today, ATmega is in place and running Currently just blink green and blue LED (red LED is connected to pin A7 and this can be just analog input and not output - what I understand from datasheet of ATMega328), I dont have slim RFM69 radio, but already ordered, test with radio is in plan for Wednesday

Another RF scanner with mini OLED 0.96 display

Has anyone noticed that a bunch of cheap Chinese "smart bands" use a nrf51822 ?
This opens some new possibilities if used as MySensors actuator !

@Joakim-Johansson
Working without problem on WIN XP, Win7 ,WIN10,

Please upload schematic

Hi,
You design it for some nice enclosure???
Regards,
MiKa

Hi,
exist some enclosures for your sensors?
MiKa

SAMD21G18A is also option for next level of mysensors support
Check moteino M0 on lowpowerlab site

Nice!

@boots33 said in i2c Lightning Sensor +:

#include "I2C.h" // the lightning sensor can communicate via SPI or I2C. This sketch uses the I2C interface

I mean this:

#include "I2C.h" // the lightning sensor can communicate via SPI or I2C. This sketch uses the I2C interface

@boots33
which I2C library did You used???

Have look here: http://www.whizoo.com/

Hi,
what enclosure did You use for it?
