From reading the description, I wasn't sure what "AER" meant. After googling a few related keywords I found a site that claims [0] the acronym stands for: address-event representation.
Can anyone explain what this is for and in how it's useful? Not asking in a sarcastic way or anything like that, I just have no familiarity with the subject.

- unwind 10y agoThis iniLabs page[1] has a description, it's pretty low-level stuff: The AER protocol is a simple protocol using a variable number of lines (bus) to transmit data, and two lines (REQ and ACK) to synchronize the data between the sender and the receiver asynchronously using a four-phase handshake. (This is also called a bundled asynchronous protocol). The ACK and REQ lines are active-low. From the last sentence, it's clear that "line" refers to a hardware signal. It's a chip-to-chip bus protocol, from what I understand. [1] http://inilabs.com/support/hardware/aer/ http://inilabs.com/support/hardware/aer/
- orbifold 10y agoThe idea is roughly that each pixel of the camera has an address, which gets send whenever the pixel has accumulated enough charge. The pixels are sensitive to changes in intensity. So you get a stream of pixel addresses from the sensor and each send address signifies a sufficiently large intensity change.
