In the previous two HID articles, we talked about stealing HID descriptors, learned about a number of cool tools you can use for HID hacking on Linux, and created a …read more Continue reading Human-Interfacing Devices: HID over I2C
I had one of those why-didn’t-I-think-of-it moments this week, reading this article about multiplexing I2C on the ESP32 microcontroller. The idea is so good, and so simple, that it’s almost …read more Continue reading Sometimes It’s the Little Things
Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but …read more Continue reading Avoid I2C Address Conflicts On ESP32 By Pin Muxing
An oscilloscope can be an expensive piece of equipment, but not every measurement needs four channels and gigahertz sampling rates. For plenty of home labs, old oscilloscopes with CRTs can …read more Continue reading ESP32 Oscilloscope Skips Screen for the Browser
If you’ve been involved with electronics and hardware hacking for awhile, there’s an excellent chance you’ve heard of the Bus Pirate. First introduced on the pages of Hackaday back in …read more Continue reading Hands On: Bus Pirate 5
A handy tool to have on the bench is a Flash chip programmer, and the ones based around the CH341A USB bus converter chip are readily available. But the chip …read more Continue reading Flash Programmer Shows Some Nifty Tricks
You’ve probably seen USB hubs with physical switches for each port, they provide a handy way to cut the power to individual devices, but only if you’re close enough to …read more Continue reading Flip the Switch on this I2C Controlled USB Hub
For as popular as the Arduino platform is, it’s not without its problems. Among those is the fact that most practical debugging is often done by placing various print statements …read more Continue reading A Usable Arduino Debugging Tool
The best part of I2C is that it is a bus that is available just about anywhere, covering a vast ecosystem of devices that offer it as a hardware-defined interface, …read more Continue reading Three Pitfalls in I2C Everyone Wishes Weren’t There
We covered [Anders Nielsen]’s 65duino project a short while ago, and now he’s back with an update video showing some more details of bit-banging I2C using plain old 6502 assembly …read more Continue reading A Simple Guide To Bit Banged I2C On The 6502
