RF Introduction

Basic RF terminology
– –
Transmitter (only TX)• Receiver (only RX)

Transceiver (both TX & RX)• SoC (Transceiver + MCU)

dBm – is a measure of RF Power referred to 1 mW (0 dBm)
……………10mW(10dBm), 500 mW (27dBm)

PER – Packet Error Rate [%] – percentage of the packets not successfully received over a period of time

Atollic debug configuration for quick DOWNLOAD and RUN

Sometimes we need to download the SW and RUN it to quickly for see the result.
This tutorial explain how to do this.

After you are sure to have a standard debug that working fine, now you are ready to create another debug configuration only for DOWNLOAD and RUN your project on the STM32.

How to use ADC in Interrupt mode

In electronics, an analog-to-digital converter (ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

There are several ADC architectures, in MCU normaly there are SAR (successive approximation register) and sometime SIGMA-DELTA (also known as a delta-sigma ADC).
SAR is very fast
SIGMA-DELTA is slow but is very precise

The stadard ADC in STM32 is SAR at 12bit but there ara also some STM32 that iclude also a SIGMA-DELTA ADC at 16bit.
