How do you select an AC adapter to safely power your microcontroller (MC) development board? Most people don’t think much about the AC adapter (power supply) for their development platform, especially if it is included in the development kit. But more often these days, kits come in small boxes with minimal accouterments, perhaps following the […]

Stack underflow when the array number is increased – I have an array defined in my code included in […]
e-MMC, UFS embedded memories integrate NAND flash and controller chip in one package
Toshiba America Electronic Components, Inc.(TAEC) has enhanced its lineup of managed NAND devices with the addition of new Embedded Multimedia Card (e–MMC) and Universal Flash Storage (UFS) embedded memory solutions. Featuring enhanced integrated controller technologies, the new ‘Supreme+’ e–MMC (JEDEC ver. 5.1) and UFS (JEDEC ver. 2.1) offerings deliver significant read and write speed improvements to […]
Real time clock (RTC) vs. clock: What is the difference?
Microcontrollers act upon instructions a few bits at a time, collecting the next batch of bits at regular intervals. Those regular intervals need to have a regular cadence for the MCU to be predictable, so MCUs have at least one clock to keep timing going at a regular pace, much like you would use a […]
MathWorks “Learn to Program” packs run on Raspberry Pi3, Arduino Uno and BeagleBone Black
Newark element14 is now stocking three new editions of the popular MathWorks Learn to Program pack, for the Raspberry Pi3, Arduino Uno and BeagleBone Black. The packs provide access to all the necessary hardware and software to get started including the board and MATLAB and Simulink Student Suite. The MathWorks Learn to Program pack enables students […]

Developers can now take advantage of the highly optimizing build tools and comprehensive debugging capabilities in IAR Embedded Workbench® to leverage the full potential of the VORAGO MCUs. The complete C/C++ compiler and debugger toolchain IAR Embedded Workbench supports new […]
Single-chip MCUs excel at FOC for motors
Toshiba America Electronic Components, Inc. (TAEC) today launched a new group of microcontrollers (MCUs) that allow a single chip with a low pin count (32 to 64 pins) to control multiple motors in Field Oriented Control (FOC) methodology. The M4K MCUs are the second product group in Toshiba’s TXZ family of high-speed, low power […]
USB 2.0 4-Port/7-Port Hub Controllers consume little power
Exar Corporation announced a family of USB 2.0 hubs that consume the least amount of power and require the smallest real-estate footprint in the industry. The XR22404 and XR22417 are designed for applications where power consumption and board space are a concern such as docking stations, point-of-sale terminals, USB port expansion, test instrumentation, factory automation […]
How to wire a switch to a microcontroller with pullup resistors
If you want a button or switch as an input on a microcontroller (MCU), you can use a “pullup resistor” so that the input is seen as a logical high when the (normally open) switch or button is closed. A pullup resistor is connected to Vcc, or logical high for your input, and therefore “pulls […]
