From the top of the webpage: *Journal > Browser Based Edition > Embedded > CHERIoT* *CHERIoT* *By David Chisnall* *CHERI* is a set of architectural extensions that provide fine-grained memory safety for everything from assembly code on up. CHERI, like Capsicum, is a capability system. In a capability system, every action must be accompanied by a capability, an unforgeable token of authority, that authorizes the action. The *CHERI* project has always had a close relationship with FreeBSD. It began from observing that Capsicum-based compartmentalization was great for new code but retrofitting it to existing libraries (with one process per library instance) was difficult for two reasons: First, libraries want to share complex data structures, which imposes a lot of serialization overhead when turning the interfaces into messages sent over some inter-procedural communication (IPC) channel. A function call in a normal library would simply share a data structure by passing a pointer to an object. A privilege-separated library would need to authorize everything moved between the caller and callee. Libraries also often want long-term sharing, which imposes additional synchronization overhead. Second, processes are isolated using a memory management unit (MMU), which provides a virtual-memory abstraction with mappings from addresses in a virtual address space to the underlying physical memory. Modern MMUs are fast because they have a translation look-aside buffer (TLB), a fast cache of translations. The TLB caches virtual to physical address translations. If a single page is shared between ten processes, it will take ten TLB entries. MMUs are great for isolation but poor for sharing. These two problems led to the general observation: Isolation is easy, sharing is hard. -- Scott G.

It's fairly straightforward to record a jitsi meeting when everyone is joining remotely using their own computer. But, doing the recording when people are in the same room becomes more complicated. In order to get decent sound, we'd need recording equipment (microphone/speakers, camera, dedicated laptop), as well as a second laptop to do the recording, which is a pain to set up. The other option is to have everyone in the room log in to jitsi individually, with one person doing the recording. Navigating feedback issues is the painful part here. If I recall from the last time we tried this, different devices had different behaviors, rendering the audio a mess. So, I think it's reasonable to expect we could record remote meetings, but much less so for in person meetings. dt On Sat, Oct 11, 2025 at 11:45 AM Dawn Trembath wrote: > Hi Carl, > > I'm pretty sure I'll be attending this month, so can do the recording. > > dt > > On Sat, Oct 11, 2025 at 9:22 AM Carl Nobile via TriEmbed < > triembed at triembed.org> wrote: > >> Speaking of a recording, I'm still in Italy, if someone else can record >> the meeting, I'll edit it when I get home after the 14th. >> Carl >> >> -------------------------------------------------------------- >> Carl J.

We just don't have access to the equipment we used for those previous recordings, so that's out for tonight. We're hoping to get together sometime before the Nov. meeting, with all equipment in tow, to recreate a working setup. We'll post instructions to the list, so anyone who's interested can set up and record future meetings. As far as tonight is concerned, a possibility would be to try using a few laptops, one to host and one to record the jitsi session. Not ideal, but might at least be able to capture audio from whoever has the host laptop in front of them.

With VBAT (USB power) off and VBAT at -4.1V, the body diode does not conducts, R8 pulls down the gate but the MOSFET is not enhanced since it is higher voltage than VBAT. 3. With VBAT (USB power) at +5 and VBAT at +4.1V, the body diode does not conduct. R8 does not pull down the gate and the MOSFET is not conducting. 4. With VBAT (USB power) at -5 and VBAT at -4.1V … We did not talk about this case. With the MOSFET installed in the forward direction: 1. With VBAT (USB power) off and VBAT at +4.1V, the body diode does not conduct, R8 pulls down the gate which enhances the MOSFET and it conducts. 2. With VBAT (USB power) off and VBAT at -4.1V, the body diode conducts and bad things happen as current flows the wrong way 3. With VBAT (USB power) at +5 and VBAT at +4.1V, the body diode conducts and current flows into the battery. Shane says he has to think through P-FETs over and over and often still gets it wrong on the first try.

Trying to control precise timing of DMA while doing LVGL and touch was problematic. Solution was to use RP2040 stamp (USB interface is via a removable ribbon cable) to control the timing sensitive stuff. I2C was used to pass JSON commands between the two processors. EDGER code lives once more. Misc Talked about tariff impacts on price and shipping. Glen Smith gave away a large quantity of nice watertight boxes with some electronics inside. Buck DC converter and some Bluetooth thing that would be difficult to reverse engineer. Paul re-discovered that shields for Arduino boards do not need to cover all of the pins. The lower 4 pins (Gnd, 3v3, 5v, D5) of a D1 mini are all you need for a project with minimal I/O requirements. -------------- next part -------------- An HTML attachment was scrubbed...

The list is  a GNU Mailman instance. It used to be trivial for users to subscribe/unsubscribe[https://mail.triembed.org/mailman/listinfo/triembed_triembed.org]  but now it's hard for some. But Mailman isn't different, some of it's users are. Putting an "easy out" mailto link at the bottom of every posting seemed like a good idea at the time. So a fraction of folks are subscribing and unsubscribing using the link above and (almost) everybody else hits the mailto and that's no problem. But I failed to check my mail for a backlog this time. The unfortunate problem with the list membership admin is that it involves a password I can't share. I'll see if I can fix this with a sharable password. This is different from list moderation that has its own sharable password. Pete -------------- next part -------------- An HTML attachment was scrubbed...

Each zone has its own local microcontroller brain that makes fast, context-aware decisions and report upstream only when necessary. It’s like having a team of specialists rather than one overworked manager. Now? That same microcontroller might be one of dozens inside a car door, or part of a swarm of sensors in a factory line. It’s no longer acting alone, it’s collaborating. Once upon a time, the MCU was the loner on a board, running the show for one simple task: spin this motor, read that sensor, toggle that LED. Straightforward, self-contained, dependable. But for that to work, all those little controllers need to talk to each other quickly and without tripping over the physical limitations of power delivery, synchronization, or signal integrity. Speed Isn’t Just in the Silicon We often talk about performance in terms of megahertz or MIPS, but for microcontrollers, data movement is becoming the real benchmark. Think about it: it doesn’t matter how smart your MCU is if it’s constantly waiting on data to arrive, or can’t synchronize with its neighbors. In distributed designs (from robotics to smart infrastructure), speed isn’t just about computation, it’s about coordination. That’s where innovations in synchronization, high-speed data transfer, and power management step in. Engineers are finding clever ways to push more data through existing hardware pipelines, to keep multiple microcontrollers operating in lockstep. The irony? The fastest systems in the world depend on slower chips that know how to talk efficiently. Smart Power, Smarter Control And then there’s power. The more intelligent and distributed our systems get, the more complex their power topologies become. That’s why modern designs rely heavily on smart power switches, which do more than just turn things on and off. They monitor current, provide diagnostics, and communicate directly with the MCU to optimize distribution in real time. It’s no longer just about protecting against shorts or overloads. It’s about letting each microcontroller act as a power manager, keeping its local zone healthy, efficient, and responsive. The Post-MCU World (That Still Runs on MCUs) The irony of our so-called “post-MCU” era is that we’ve never depended on microcontrollers more. They’re everywhere: hidden inside EVs, test systems, industrial robots, even the devices that program other devices. But they’re no longer defined by what’s inside them. Their value comes from how they connect, how they communicate, and how gracefully they cooperate. The frontier of embedded design isn’t about squeezing more horsepower into a single chip, it’s about designing the circulatory system that connects thousands of them. The Future Lies Between the Lines As embedded systems grow more distributed, the measure of a microcontroller’s worth is shifting from processing to participation. The brilliance now lies in orchestration: how data, power, and timing converge without friction. It’s no longer enough for a chip to be fast; it must be fluent. The engineers who master those invisible interfaces (the arteries of data) will define the future of microcontrollers and the future of every system they touch. Want to read more?
