Adding a RTOS (Real Time Operative System) To Your Project with Keil MDK5

There is a lot of information on the web about Real Time Operative Systems, but i will be very fast because i am not an expert nor a genius in this and other themes. This is a combination of software and hardware requirements to do real time applications. Like computers that have an Operative System …

Running the FRDM-K64F Bootloader Option

  The bootloader is a firmware program, and in our case, with our microcontroller is resided in flash memory.  Basically loads main functionality of all interface and peripherals and has command line interface tools to make an upgrade of our existing application. A better use of a bootloader is to implement in a serial line …

Connected LaunchPad – Tiva C Series

Tiva C Series microcontrollers are the “new” ARM Cortex-M with capability of floating point operations.  They are 32-bit microcontrollers that have embedded USB, Ethernet, GPIO, Timers, and so on peripherals for your application use. What is impressive is the price, the TI Connected LaunchPad that i am evaluating only costs USD 19.99 and you could plug …

Variable Speed Drive Control in LabVIEW

There is often called Variable Speed Drive or Variable Frequency Drive.  These devices are used to control speed and torque during the timespan of the application. Check the cool application in LabVIEW using an old and common protocol like Modbus TCP that is very common in industrial control applications.

Ubertooth One – Bluetooth Packet Sniffing Hardware and More

Ubertooth One is a Kickstarter project by Michael Ossmann to make experiments under the 2.4GHz band.  Is a development platform for wireless but you can specially do more than that.  You could sniff bluetooth packets with kismet and log it to later open in wireshark and analyze.  This is very usefull to make drivers and inspect bluetooth …
