Third version of homemade 6 GHz FMCW radar

Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with minimal budget and there was a lot of room for improvement. FMCW radar working principle If you have read my previous articles you should know how FMCW radar works, but for completeness sake short explanation is given b ...

MaxProLogic: Ultra Low Cost FPGA Development Board

SWEETENING THE DEAL With a few days left in our campaign, we will sweeten the MaxProLogic deal. We will now offer our newly developed BLE Board. This board includes the Texas Instruments CC2640 chip along with a 2.4GHz antenna and matching network. This board plugs directly into MaxProLogic. It communicates with the FPGA over a UART serial link. The CC2640 runs proprietary firmware along with the radio cont ...

WISP – RE-PROGRAMMABLE MICROCONTROLLER THAT RUNS ON ENERGY HARVESTED FROM RADIO WAVES

A new research initiative between the University of Washington’s Sensor Laband the Technical University of Delft in the Netherlands has created a microprocessor that can power itself through stray radio waves and receive programmable updates in the same fashion. While the RISC-derived 16-bit microcontroller CPU is very weak compared to modern standards, it’s much more powerful than any other device that’s p ...

I2C COMMUNICATION WITH PIC MICROCONTROLLER

I2C COMMUNICATION WITH PIC MICROCONTROLLER: I²C stands for Inter-Integrated Circuit. It is a short distance serial interface that requires only two bus lines for bi-directional data transfer. It is used for attaching lower speed peripheral ICs to microcontrollers in short distance communication. Low speed peripherals include external EEPROMs, digital sensors, lcd, etc. Page Contents 1 I2C communication PROT ...

Timers of PIC microcontroller How to generate delay

USING TIMERS IN PIC18F452 MICROCONTROLLER:Timers and counters are important as timers can tell the time and count. Counting and timing allows for controlling the brightness of LEDs, controlling the angle of servo shafts and PWM signal generation etc.  All microcontrollers have clocks in them or they use the one that resides outside of a microcontroller. Microcontroller needs clock so our programs can be exe ...

One-Size-Fits-All Battery Charger

The first step to designing a battery charger is choosing a battery charger IC from the vast field of available solutions. To make an informed decision, a design team must first clearly define the battery parameters (chemistry, cell count, etc.) and the input parameters (solar, USB, etc.). The team must then search for chargers that fit the input and output parameters, comparing numerous data sheets to sett ...

parking management system project using pic microcontroller

parking management system, we aim to create a smart parking system which will not only calculate the total capacity for cars in the parking area but will also direct the cars to an empty spot where they can park their cars in an orderly fashion. This parking management system will require at least 6-8 proximity sensors to detect the presence or absence of a car and also to detect if a car has entered the pa ...
