PCF8591 has one 8 bit ADC on board for 4 channels. The ADC is 8 bit and quite fast. At 100 KHz one gets more than 2000 reads per second for read() and more than 2000 writes per second for write().

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

While it’s likely seldom done, some vehicles’ maintenance schedules do include an interval for changing the differential fluid, though perhaps only under “severe service” conditions such as frequent ...

The realm of automotive technology is rife with jargon and acronyms, from ABS (Anti-Lock Brake System) — which first appeared in 1978 — to ZEV (Zero-Emissions Vehicles). Sitting squarely between those ...

The MultiCalculator is built around a Pro Mini and is programmable, even after the construction is finished, through a 6way female header at the back. The software is bilingual, the menu language can ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

As far as car fluids go, differential oil is one of the most neglected pieces of maintenance. It could be because the effects of not changing differential fluid on time aren't as immediately obvious ...

Last time, we’ve used a logic analyzer to investigate the ID_SD and ID_SC pins on a Raspberry Pi, which turned out to be regular I2C, and then we hacked hotplug into the Raspberry Pi camera code with ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

In the automotive world, especially when it comes to off-road trucks and SUVs, differentials come up all the time. Is your differential locking, limited slip or open? Do you have a transfer case? One ...
