The Serial Peripheral Interface (SPI) interface was initially standardized by Motorola in 1979 for short-distance communication in embedded systems. In its most common four-wire configuration, full-duplex data transfer is possible …read more Continue reading Bare-Metal STM32: Setting Up And Using SPI
Dangerous machines, like ones that can quickly reduce you to a fine red mist or a smoking cinder, tend to have a Big Red Button™ to immediately stop whatever the …read more Continue reading Slap This Big Red Button for an Instant Social Media Detox
Teaching people efficiently isn’t limited to transmitting material from one head to another — it’s also about conveying the principles that got us there. [Mara Bos] shows us a toolkit …read more Continue reading Boards For Playful Exploration Of Digital Protocols
It used to be that to play a console game, you just had to plug in a cartridge or put a CD/DVD in the optical drive. But these days, with …read more Continue reading PS2 Memory Card ISO Loader Offers Classic Gaming Bliss
Sometimes reverse engineering embedded systems can be a right old faff, with you needing to resort to all kinds of tricks such as power glitching in order to poke a …read more Continue reading Linux Arcade Cab Gives Up Its Secrets Too Easily
We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the …read more Continue reading Did You Know That The Raspberry Pi 4 Has More SPI, I2C, UART Ports?
You could argue that the project to add a round screen to a Raspberry Pi from [YamS1] isn’t strictly necessary. After all, you could use a square display with a …read more Continue reading Tackle the Monkey: Raspberry Pi Gets Round Screen
Imagine you’re sending a piece of hardware to space on a satellite. Unless you’re buddy-buddy with NASA, it’s pretty unlikely you’ll ever be able to head up there and fix …read more Continue reading Robust I2C and SPI In Space Thanks To Bus Isolation
