RRenuel Roberts Did u add d logic to filter out the unexpected/garbage characters

segfaultdev.elf•11/9/24, 8:53 AM

it is happening as i hit the reset button

segfaultdev.elf•11/9/24, 8:53 AM

there is no code to run at that stage

Renuel RobertsOP•11/9/24, 9:02 AM

Is ur pull up resistor closed to ur uart input pin

ZacckOsiemo•11/9/24, 9:22 AM

is it corrupting anything or just spurios noise on power cycle?

segfaultdev.elf•11/9/24, 9:23 AM

noise on power cycle

ZacckOsiemo•11/9/24, 9:23 AM

have you read the datasheet, go through that power up and power down sequence again

ZacckOsiemo•11/9/24, 9:24 AM

There could be some work happening during power cycle that you may not be able to change

Here's a discussion where you'll find it worked with core version 2.0.6. Please follow the entire conversation https://github.com/espressif/arduino-esp32/issues/6876. It seems to be an issue with the HC-06 & library version conflict

@Ready to Work, a couple updates:

The Assembly job "req" I posted earlier this week is still being defined. They said they should have answers on Monday, at which point I'll share more with those who indicated they were interested in the position.
We're partnering with @Marcweb of Webster and Webster on jobs and @JoeSchneider's firmware org Dojo Five has some positions open. You can find more from both in the #jobs channel.

Hello every one i have little problem about scada system on panneaux solaire the problem is i wanna make another interface to show information from server ..
So we used here serial comminecation rs485 modbus
And i can get addressage of All information like exp when i recive 62800 i kn its for curant or voltage and so on ..
So the qst is how to mapping all address i kn with the new one like i kn 62800 for voltage but voltage update each second for exp

addalaabderrahim•11/9/24, 2:58 PM

So i wanna mapping the new information with old address to know this info for voltage

Umesh Lokhande•11/10/24, 5:17 AM

Hi @addalaabderrahim, if you mean that your Modbus address is 62800, which you use to receive voltage information, then the address for reading voltage will not change. Each Modbus address corresponds to a specific parameter when read, and the data size (whether it's 1 byte or 2 bytes) depends on the documentation's mapping of addresses and their respective parameters. I recommend reviewing the documentation to understand the expected data format for each address. Personally, I follow the sequence of addresses to interpret the data received from Modbus. Hope this may help you, best wishes!

addalaabderrahim•11/10/24, 6:14 AM

Ah yes yes thx man ,i will try mapping all adress and if i get problem i will ask

Hi everyone, Sunday Robotics is here

kristof-at-embeetle•11/10/24, 9:02 AM

Hey guys,
I want to present to you Mehmet from @sundayrobotics . He has a cool product

kristof-at-embeetle•11/10/24, 9:09 AM

kristof-at-embeetle•11/10/24, 9:09 AM

Ideal for schools, universities and prototyping in general

kristof-at-embeetle•11/10/24, 9:09 AM

Mehmet is completing his website in a few days.

kristof-at-embeetle•11/10/24, 9:10 AM

I invited Mehmet to the DevHeads community. He fits here perfectly

ProBUDDY Kits emerged from the challenges we faced with space limitations and project-related issues. Initially, we used them ourselves, then launched a campaign on Kickstarter to fund the idea. Now, as a small robotics startup, we are offering them to all technical professionals.

Salih Brother•11/10/24, 9:13 AM

Not just for this product ecosystem, but in general, I’ll be delighted to connect and engage with you on technical topics.

Salih Brother•11/10/24, 10:40 PM

Thank you @techielew let me explain that.. We engineers and developers often work on multiple hardware and software projects within a small space.. Especially while rents are going higher and higher.. Our workspace is filled with numerous interconnected electronic boards and cables, which can quickly turn into a chaotic environment. In this chaos, a short circuit or a loose connection can cost us days of valuable time.. So, around 2 years ago, as we were struggling with problems in our small and chaotic workspace, we started searching for a solution that could organize our electronic work environment. We created metal plates and magnetic holders, attaching all our project components—electronic circuits, sensors, and cables—to these plates. As a result, the errors we previously encountered were eliminated, and we began working in a highly organized manner.

We even found a way to hang our projects on the walls of our workspace. Later, we designed racks for these metal plates, allowing us to store 6-8 projects within them. This made it easy to take a project from the wall or rack, place it on our desk, and switch it out for a new one when needed. Thanks to this system, we went from being able to work on 1-2 chaotic projects in a small space to efficiently handling 8-10 organized projects in the same area. Carrying and demonstrating the projects became much more easier and professional-looking.

We further developed this product family, converted it into an ecosystem and named it ProBUDDY Kits. Now it has 50+ items covering many types of holders, baseplates, stands, racks, electronics to 3d printable files.. Now it became so helpful for almost any project, any scenario

ke7c2mi•11/10/24, 11:17 PM

This speaks direcly to me and I am eyeing the kickstarter ... I currently have several boards strewn in the space under my monitor. I was thinking to get some copper clad board and drill it with standoffs to tidy things up for just that project.

I've always wanted some sort of rack I could keep a set of shelves in and put one on my desk when I needed it (i.e. the shelves come out of the rack to sit on the desk)

But it looks like you have nailed the concept and made it slick
