ACould you send a clearer picture of the ICs?
UIn a production scenario, you can use jenkins server with a docker image running on RPi. This will allow automation for Continuous Integration/Continuous Deployment (CI/CD) and also can be useful for data collection and processing. I hope this answers the question.
YThank You, I'll take a look and give you my feed back
SI tried installing Jenkins on my Raspberry Pi but ran into some errors. Running a Docker image instead would be good Thanks!.
Can you suggest if any, a small experiment kind of I could try to understand the use of Jenkins in IoT?
i searched for use cases but they were complex.

MSo guys I'm adding FreeRTOS to my device, but I'm stuck on task priorities. Even though I've checked everything I could check, higher-priority tasks aren't interrupting lower ones , preempting as it's called. Any ideas on what might be causing this?
TI've never heard of anyone trying something like this. As I'm sure you're aware, Jenkins is primarily a build/test/release automation tool. So, not sure if I know of any example use cases. Might check out Dojo 5 blog: https://dojofive.com/blog.
TSounds like you might be dealing with a priority inversion, which can happen when the lower priority tasks continues because of a mutex or semaphore
TCheck out Shawn's blog on Digi-Key: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-11-priority-inversion/abf4b8f7cd4a4c70bece35678d178321
DigiKey
Priority inversion occurs when a high priority task yields to a low priority task because the low priority task holds a lock, such as a mutex or semaphore, needed by the high priority task.

SI was working with #ArduinoMega and here I am with a new blog !
In this blog, I am carrying forward my previous work on the Modbus RTU Function Subset Implementation based on a Generic Library. I had tested this library on Cypress PSoC5 and TI Stellaris Launchpad Kit. This time I have tested it with Arduino Mega and Uno.

DHi guys I facing this issue with my esp32-s3 timer isr i am using platformio esp-idf any clue to solve this warning?
THey @shaunak this is amazing. Is the repo private? Can we fork it to the DH repo?
Ngreat detials, @shaunak !
T@Umesh Lokhande @MCU, MPU & Firmware gang? Any help for @kingrom?
ADeclaration (src/Test_timer.c:32:23): This is where the function is first introduced before its actual definition. Make sure the section attribute here matches the one you intend to use.
Definition (src/Test_timer.c:51:1): This is where the function's code is actually written. The section attribute here must match the one in the declaration.
Choose which section you actually want to use (.iram1.0 or .iram1.1), and then make sure both the declaration and definition of timer_callback use that same section. Hope this will resolve the warning.
@Umesh Lokhande @MCU, MPU & Firmware seniors Please give feedback about the answer

Dwhat is (.iram1.0 or .iram1.1) ?
UThis represents memory regions inside the internal RAM (IRAM) of ESP32. I don't use PlatformIO but usually because of the deprecated
timer.h build failed. In your case, it seems like IDE couldn't locate the relevant libraries. Please try this example code to test and also follow instructions from the readme file https://github.com/espressif/esp-idf/blob/master/examples/system/esp_timer/main/esp_timer_example_main.cDthank you

FHi
CHello everyone, I have some concerns bothering me.I would like to know how one can estimate the lifespan of a microcontroller (for example AVR).
And can microcontrollers work 24/7 ??
And can microcontrollers work 24/7 ??
AMicrocontroller lifespan estimation depends on operational and environmental conditions. Properly designed microcontrollers can work 24/7 with adequate power management and cooling.
CHum actually I want to use the AVR for a project that will run for several days maybe. I would like to know if the AVR will be able to handle it.
AMost avr can work 24/7, the most important thing is to keep cooling and low humidity and away from Dust t, these are the ennemis of electronics 
CHaha yeah

JHello, I'm working on an article about why you should consider .8mm PCBs over 1.6mm PCBs (mostly in the context of 2-layer boards). Anything I should mention?
I'm not advocating that in all cases over 1.6mm thickness, but seems like something that beginners especially wouldn't even consider I think the most obvious factors are weight, volume, and cost, but I know captive issues come into play as well. Any insight/references on capacitance that I should look at?
Also I saw some mention of how it affects solder joint fatigue, would welcome your thoughts on that too!

JActually, one thing I'd looked at a while ago is the RP2040 design guide https://datasheets.raspberrypi.com/rp2040/hardware-design-with-rp2040.pdf, section 2.4.1, where it talks about the differential impedance for the USB spec and having a ground plane nearby. Not certain if the distance to the ground plane actually affects characteristic impedance, or if that is a separate solution for minimizing crosstalk. Thoughts?
THi @everyone!

KHi,
I'm trying to let Google Gemini access a codefile that is too large for ChatGPT4. Gemini has a larger context size compared to GPT4. However, I can't upload a text/code file to Gemini. I try to give it links to a publicly available text file so it can read it from there. I tried the following:
Has anyone here achieved to get Google Gemini analyze a text file?
PS: the text file (code file) is too large to copy-paste into the prompt.

As a successful IoT professional, you not only have to be an experienced technologist. You also need a decent amount of domain expertise, business savvy, and preferably all three.
