It enables makers, IoT enthusiasts and professionals to build easily connected projects based on a wide range of hardware including not only Arduino boards, but also ESP32 and ESP8266 boards. Arduino is committed to making all the Arduino Cloud features available to all the supported [14:01] schestowitz hardware and as a result of this effort, ESP32 family of chipsets now support over-the-air (OTA) updates.

The metal layer on top of the chip is visible, with the silicon and polysilicon mostly hidden underneath. Around the edges of the die, bond wires connect pads to the chip's 40 external pins. I've labeled the key functional blocks; the ones that are important to this discussion are darker and will be discussed in detail below. [14:07] schestowitz Architecturally, the chip is partitioned into a Bus Interface Unit (BIU) at the top and an Execution Unit (EU) below. The BIU handles memory accesses, while the Execution Unit (EU) executes instructions. Most of the relevant circuitry is in the Execution Unit, such as the condition evaluation circuitry near the center, and the microcode in the lower right. But the Bus Interface Unit plays a part too, holding and modifying the program counter.

[14:08] schestowitz[14:08] schestowitzIf you frequent driving ranges, youve probably seen a machine (often attached to the front of an armored golf cart) designed to pick up golf balls. Because a driving range can easily fill up with thousands of golf balls an hour, such machines are necessary. After noticing that nobody wanted to pick up the ping pong balls after matches, Maxime Monsieur and his team (Oumaima Achkif, Reda El Marsse, and [14:08] schestowitz Amir Farbod) built this robot that collects ping pong balls using a mechanism similar to those used for golf balls.

I have four slots on the schedule (wow! Thanks for arranging these, FOSDEM team) and Ill be talking about several projects. There is a quick lightning talk on Saturday to introduce Helios and tease a full-length talk on Sunday, a meetup for the [14:19] schestowitz Hare community, and a meetup for the SourceHut community. I hope to see you there!
