Hi,
Has anyone converted the Adafruit graphics library for Arduino, Adafruit_GFX.h, to be compatible with the nRF51?
Could you please advise on how to convert this Arduino...
Hi all,
I have a few questions:
How is that ADC's common mode rejection capabilities? Rejection for 60 Hz interference, etc...
The datasheet has "typical...
Hi all !

We have recently moved to a new PCB which puts the nRF8001 on the layout instead of plugging into a nRF2741 development module. The nRF8001 connects to a TI Cortex-M4 Tiva...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
To be more detailed:
One of my ADC pins will be connected to another device that could be providing a voltage of about 3V, but through a 100 kohm resistor. (actually it...
