By “when the code runs” do you mean encrypt the binary?

UWhy 10-bit I2C Slave Addressing is not widely used in device libraries and example codes? Even, I often use a 7-bit slave address. It seems to me that either 10-bit addressing is only for special cases or it's a bit of a challenge to implement in code. Appreciate any perspective, experience @abhishek awasthi @Navadeep @ShreeshaN @Aditya thakekar
BHi @techielew , encrypt the .py source code or .pyc compiled code and decrypt them on the fly so the Python interpreter could run it.
I was curious about the best practices in doing so. Thanks

SMy guess is that use of 8-bit or 10-bit slave address will add a byte more in every communication packet of data and considering slow speed of I2C, devices using 8-bit or 10-bit are not popular and adding extra implementation of addressing will increase I2C device library for small microcontrollers.

HI'm a cybersecurity student at National University, and previously was an intern at tinyvision.ai inc. (the company that made the Upduino v3 ice40 FPGA dev board)
UI agree though. Not sure who will love this 10-bit addressing and implementation. I wonder even for MPU users are there enough bus drivers support for 10-bit I2C addresses in user space packages
TIs this for a commercial project? How imperative is it that either the source or the binary are encrypted? What are you concerned about protecting against? IP theft/cloning? Vulnerabilities? Something else?
There are commercial products like IAR Embedded Trust that provide application encryption and other security measures. And other services that encrypt binaries. Of course, those aren't FOSS..

AMost mcu work on the assumption that slave disables itself on not receiving matching address. 10 bit is used in STM32 series but not all support. NACK is disabled function.
PThank you @Joseph Ogbonna @techielew

NMakes sense. As well, 10-bit one can address upto (2^10)-1 devices. But come on, I haven't seen anyone using even 127 device itself on a single bus.
NCurious: What was your highest? I've used 8 of them multiplexed with the same address and 8 such ones in a single bus. In SPI though I've seen designs having 64 subordinate nodes.
AYes that's another... Haven't seen that high of a bus load either

NWelcome to the server! Happy to have you as a DevHead!
NThe question will be: " Quelles initiatives ou stratégies le département entreprend-il actuellement pour rester à l'avant-garde des technologies émergentes et garantir que les étudiants soient bien équipés des compétences et des connaissances nécessaires pour les domaines en constante évolution de l'électronique, des sciences informatiques et des systèmes embarqués ? " lol
LGoogle saved me once again That is a great question (and I've already got it on my agenda

KHi guys,
I'm using the following PTC fuse to protect the Tiny Scarab board (and the PC you're plugging it in):

K
KThe part number is
KIt's a PTC resettable fuse that can hold 500 mA. As per the USB standard, that should be fine. The PC should be able to deliver 500 mA on each USB port without damaging itself.
KHowever, I'm a bit worried about two things:
K1) The will trip only at 1A. In other words, the trip current is twice as high as the hold current. Isn't that a bit dangerous for the PC?
2) The has a R_min of . That looks okay. However, the is . The datasheet says: R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. Could this be a problem?
