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,

this one with nodic 52832

Hi,
Varistor and fuse is always good to use as a protection
Its lot of cases of start the fire in house from cheap AC/DC converters.

MiKa

next nice board with NRF 52832

Problem solved with pull-up! Thanks!

Hi,
Works !!!
Thanks Ptibu!

Have look here: http://www.whizoo.com/
and source code: https://github.com/engineertype/ControLeo/tree/master/ControLeo/examples/ReflowWizard

Im using now mainly NRF51 and SAMD21 MCU, both of them have lot of advantages FLASH, interrupt on all pins, consumption.....

Thanks,Compilation OK
