NEW PARTS, NEW HACKS

The biggest news this week is that Raspberry Pi is no longer synonymous with single-board Linux computers: they’re dipping their toes into the microcontroller business with their first chip: the RP2040, and the supporting breakout board, the Pico. It’s an affordable, capable microcontroller being made by a firm that’s never made microcontrollers before, so that’s newsy. The …

Inexpensive chip-based device may transform spectrometry

Tiny device could replace expensive lab-scale equipment for many applications. Spectrometers — devices that distinguish different wavelengths of light and are used to determine the chemical composition of everything from laboratory materials to distant stars — are large devices with six-figure price tags, and tend to be found in large university and industry labs or …

Two bits per transistor: high-density ROM in Intel’s 8087 floating point chip

Ken Shirriff has a detailed write-up about the multi-level ROM in Intel’s 8087 floating point chip: The 8087 chip provided fast floating point arithmetic for the original IBM PC and became part of the x86 architecture used today. One unusual feature of the 8087 is it contained a multi-level ROM (Read-Only Memory) that stored two …

Connectivity and speed at the core of latest Odroid maker board

Though many alternatives are available, the Raspberry Pi computer boards are probably the most well known and widely used in the maker community. But they don’t suit every project, and Hardkernel recognizes that there’s a strong market for more powerful, more capable and more expensive boards. And the Odroid N2 ticks all of those boxes. Hardkernel has …

AMD claims ARM and x86 mobile chip first

AMD has combined ARM and x86 processors in its latest mobile accelerated processing units (APUs). This is AMD’s first implementation of ARM-based technology into processors designed for consumer and commercial client devices. The mobile APUs, formerly codenamed “Beema” and “Mullins,”incorporate up to four newly-designed x86 CPU cores and a hardware-level data security solution based on the ARM Cortex-A5 processor core.Products based …

Interfacing an SPI ADC (MCP3008) chip to the Raspberry Pi using C++ (spidev)

In this entry I will demonstrate how to interface the MCP3008; an SPI-based analog to digital converter (ADC) integrated chip, to the Raspberry Pi. This enables  the Raspberry Pi to interpret analog voltages that are in turn typically emitted by analog-based sensors to reflect a measure of  a physical characteristic such as acceleration, light intensity …
