Declaration (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

what is (.iram1.0 or .iram1.1) ?

DDonald Will what is (.iram1.0 or .iram1.1) ?

This represents memory regions inside the internal RAM (IRAM) of ESP32. I don't use PlatformIO but usually because of the deprecated timer.htimer.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 filereadme file https://github.com/espressif/esp-idf/blob/master/examples/system/esp_timer/main/esp_timer_example_main.c

Hello 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 ??

aymen ammari•4/2/24, 1:47 PM

Microcontroller lifespan estimation depends on operational and environmental conditions. Properly designed microcontrollers can work 24/7 with adequate power management and cooling.

Most 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

JeremyCook•4/2/24, 4:33 PM

Hello, 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!

JeremyCook•4/2/24, 7:15 PM

Actually, 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?

techielew•4/2/24, 9:45 PM

Hi @everyone!
Looking forward to seeing you at this week's Office Hours Meetup! @barafael will be sharing his experience as a Rust programmer, @wafa_athmani will talk about micropython, while other devs touch on their language of choice.

See you on Friday at 15:00 GMT: https://discord.gg/HQKgbpGQ?event=1224832746271150194

Hi,
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:

a link to a text file on our own server
a link to a text file on a public Github repo
a link to a (publicly available) text file on my Google Drive

But Google Gemini fails to read any of them. It always says that it can't access the file.

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.

Calling all @PCB & Analog engineers: Don't miss the premiere of our next Ask a Developer Demo with @ShreeshaN on April 3rd at 15:00 GMT (in 10 hours). He walks through selecting an LDO with LTSpice, comparing an Analog Devices voltage regulator and Linear Technologies voltage regulator in a theoretical battery application.

A great place to start if you're just getting your hands dirty in electrical design.

kristof-at-embeetle•4/3/24, 5:38 AM

I can't even upload a single file to Google Gemini. Let alone multiple at once.

@onky I know you had been asking about the Office Hours recordings a while back. We've got a bunch of them now available here: https://www.youtube.com/watch?v=MadlOBr-K1w&list=PL2mKSkagAaJjiMdJ3MqRqUEDGi_Y79Cpe

We're playing catchup so the first episode from February is currently uploading but we'll get current over the next couple weeks. Thought you'd want to know.
