New PIC32MM “GPM” microcontrollers are now available from Microchip Technology Inc. The eXtreme Low Power (XLP) devices feature large memory in small packages, providing ample battery life for space-constrained applications. With the inclusion of several connectivity options, Core Independent Peripherals and feature-rich development boards, the “GPM” MCUs are well suited for digital audio applications, gaming/entertainment devices...

The second version of the controller is made on a popular  Wi-Fi module such as NodeMCU, which is based on the powerful Espressif ESP8266 system-on-chip. Such a solution will allow us to implement in our light controller additional functions inherent in the devices of the Internet of things...

The ubiquitous LCD (and VFD) modules based on the HD44780 controller IC can require up to 12 lines from the host. This hardware interface Design Idea  reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard interface, or even an opto-isolator...

The 32-bit PIC32MZ DA microcontroller family is the industry’s first MCU with an integrated 2D Graphics Processing Unit and up to 32 MB of integrated DDR2 memory. This combination from Microchip Technology Inc. gives customers  the ability to increase their application’s color resolution and display size...

Just over 2 years ago the Raspberry Pi foundation launched the original Compute Module (CM1), which was based around the same BCM2835 processor of the original Raspberry Pi. The Raspberry Pi Foundation launched this board aimed at the industrial market, where companies were using the Raspberry Pi for commercial purposes...

As shown in previous sections, active filtering and CMRR can reliably reduce circuit noise in the device’s band-limited range, including DM and CM EMI up into the MHz range. However, exposure to RFI noise above the intended operating frequency range may cause non-linear behavior in the device...

The creation of cost-efficient and compact industrial slave devices that can connect to any Real-Time Ethernet network is now simplified through the combination of the STMicroelectronics STM32 ecosystem with the multi-protocol flexibility of Hilscher’s netX control ICs...

STMicroelectronics has begun volume production of ultra-low-power STM32L45x microcontrollers, supported by a development ecosystem based on the easy-to-use and affordable STM32Cube platform. The STM32L451, STM32L452, and STM32L462 lines integrate a Digital Filter for Sigma-Delta Modulators, enabling advanced audio capabilities such as noise cancellation or sound localization on an inexpensive microcontroller...

The newest family of PIC32 microcontrollers is now available from Microchip Technology Inc. The PIC32MK family features four highly integrated MCUs for precision dual Motor Control applications and eight MCUs packed with serial communication modules for General Purpose  applications...

The new high-connectivity STM32L4 IoT Discovery kit (B-L475E-IOT01A) from STMicroelectronics gives unrivalled flexibility for developers building IoT  nodes by supporting multiple low-power wireless standards and Wi-Fi , while integrating a complete collection of motion, gesture, and environmental sensors, unavailable on other kits in the market...
