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 ;) :+1:

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.
Regards,
MiKa

next nice board with NRF 52832

Hi,
Works !!! :) :thumbsup:
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 :+1:
