ST consolidates programming for Arm-based STM32 MCUs

STMicroelectronics has introduced an all-in-one multi-OS software tool for programming its Arm-based STM32 products. From now on, new STM32 products will be supported only the tool, to be called STM32CubeProg, so it obsoletes existing tools including: ST Visual Programmer (STVP) DFuSe USB Device Firmware Upgrade programmer Windows-only STM32 Flash loader software utilities for use with ...

Gate driver for 1.7-4.5kV IGBTs and SiC transistors

Power Integrations created an isolated gate drive system for up to four paralleled 1.7-4.5kV power modules – either IGBT or silicon carbide mosfet. Called Scale-iFlex, it is dual channel so, for example, independent control of high and low-side switches in a half-bridge is possible. “The system is optimised for the latest 1,700V to 3,300V rated ...

Data-over-sound SDK for Arm Cortex-M

London-based data-over-sound company Chirp has released an SDK for Arm Cortex-M4 and M7 processors. The SDK exists as a static library (~740kbyte), providing a software-defined data-over-sound solution optimised for Arm processors, with an API for sending and receiving data through existing audio chains between existing loudspeakers and microphones. The SDK implements the physical and data ...

Raspberry Pi 4: far more powerful, tuned for industry

Raspberry Pi 4 has been revealed, as a far more powerful machine than even the Pi 3 Model B+. Three times the processing power and four times the multimedia performance are claimed. It has quad 1.5GHz Arm Cortex-A72 cores, Gbit Ethernet, 4Kp60 HEVC video decode and dual HDMI outputs to run twin 4K monitors – ...

Stretchy heart monitor tattoo measures electrical and mechanical body signals

Electrocardiograph and seismocardiograph readings can be taken simultaneously by an e-tattoo, according to the University of Texas at Austin – seismocardiography (SCG) is a measure of chest vibrations associated with heartbeats. “We can get much greater insight into heart health by the synchronous collection of data from both sources,” said Austin engineer Nanshu Lu. The active ...

Compound semi transistor stores data with less energy than DRAM or flash

Researchers at the University of Lancaster have created a non-volatile memory that might eventually store data for 1% of the energy required by DRAM and 0.1% that of flash – both modelled at 20nm. “Our device has an intrinsic data storage time that is predicted to exceed the age of the Universe, yet it can ...
