Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced from EE Live! and the Embedded Systems Conference in San Jose the PIC16(L)F170X and PIC16(L)F171X family of 8-bit microcontrollers (MCUs), which combine a rich set of intelligent analog and core independent peripherals, along with cost-effective pricing and eXtreme Low Power (XLP) technology. Available in 14-, 20-, 28-, and 40/44-pin packages, the 11-member PIC16F170X/171X family of MCUs integrates two Op Amps to drive analog control loops, sensor amplification and basic signal conditioning, while reducing system cost and board space. These new devices also offer built-in Zero Cross Detect (ZCD) to simplify TRIAC

Displaying temperature and humidity on servo-driven analog panels

This thermometer and hygrometer project from Kerry Wong’s website illustrates a technique of constructing analog display panels where the display needles are controlled through servo motors. The project uses the SHT21 digital sensor and the ATMega328p microcontroller.

Snow weighing scale

Posted on March 7, 2014 by R-B Leave a comment

Snowfall is typically measured in inches. However, when it comes to shoveling snow off the driveway, your would probably like to know how dense the snow has accumulated because that is what going to determine how much effort and time you will need to complete the task. This instructable shows how to modify a simple digital weighing scale to construct a snow monitoring scale which could be a nice addition to your DIY weather station.

New STM32 Nucleo development boards are mbed-enabled and support Arduino connectivity

Posted on March 3, 2014 by R-B Leave a comment

STMicroelectronics reveals affordable, extensible platform called STM32 Nucleo for efficient prototyping with STM32 Microcontrollers. The STM32 Nucleo development boards are mbed supported, and have Arduino pin headers on board so that the tons of existing Arduino shields can be easily used with these boards. The new STM32 Nucleo boards are mbed-enabled, and support Arduino connectivity while also providing ST Morpho extension headers that allow access to all of the microcontroller’s on-chip peripherals. As an mbed-enabled board, developers can make use of the mbed open source software platform, online tools and collaboration infrastructure at mbed.org. The board’s Arduino headers accept shields from the extensive Arduino

Catweazle Mini: A Trinket type tiny development board for NXP LPC810 ARM Cortex M0+

Posted on March 2, 2014 by R-B Leave a comment

NXP LPC810 ARM Cortex M0+ is a 32-bit ARM MCU that could run at 30MHz and has 6 general purpose IO, 4K flash, 1K SRAM, 2 Timers, SPI, I2C and UART. The Catweazle Mini is a Trinket-type embedded development board for NXP LPC810 ARM Cortex M0+. The built in bootloader enables flash programming with a simple serial FTDI cable.
