Hi @accur4te If you don't mind could you tell us the exact instrument that you're trying to interface with ESP32 over RS485? Because you may need a salve ID/commands to communicate with the master microcontroller.

Umesh LokhandeOP•6/12/24, 8:14 AM

I guess you'll find the details about addressing scheme or the format of the data packets, including how to address specific devices (slaves) on the bus. So that you can write code for esp32 to read flow meter data.

Hey @Event Pings,
Good news/bad news. Good news is we have another Engineering Hour coming up this Friday on getting started with Direct Memory Access (DMA) from @Edison @Edison_ngunjiri: https://discord.gg/7sJVtCyhSc?event=1250671812329607218. He'll be taking us from basic concept to real-world applications and of course a demo of memory to memory data transfers, here on Sunday, June 16th at 15:00 GMT. This is the first in a series towards timing, interrupts, and then OS-based design.

Now for the bad news, and sorry for the short notice—I've got a last-minute conflict so I won't be able to host Office Hours tomorrow morning, which breaks an almost 8-month streak! But don't get too down, as next Friday, June 21st, we'll be back in Office Hours at the usual time of 15:00 GMT to continue our exploration of Zephyr with @ZacckOsiemo. Again, you can access that through the server event listings.

Of course, as always, keep the collab going in the server!

I guess it's due to time zones.

Yeah!.. I have to choose a project which I am going to work on but I am confused, what should I choose , I have thought of an audio amplifier only with transistors no ic, a helium balloon control with esp, or a hand motion capture gloves. Idk what should I choose, do you have any other suggestions, i am a beginner btw

Accur4te•6/17/24, 5:35 AM

Umesh LokhandeOP•6/17/24, 6:55 AM

Hi @accur4te The error seems to be because of a corrupt workplace or maybe an incorrect debug configuration in STM32CubeIDE. So right-click on the project name, run clean-up, then make sure the debug settings, and try again. Please tell us more about which exact debugger/board/settings you're using while this error shows up.

Umesh LokhandeOP•6/18/24, 4:59 AM

Hi, you haven't mentioned which programmer/debugger you're using. If you're using STLinkV2 Programmer with a custom STM32 board then check the pin connection/circuit twice. Also, make sure if in case the programmer is a clone then test it before programming a custom STM32 board. The more details you provide on h/w connection better we can help. Happy learning!

Accur4te•6/18/24, 4:36 PM

Few days ago on this server I posted about I want to extract data from a rs485 flow meter , Adler the suggestion I did write the code the communication between arduino and flow meter was successfully but , it’s unable to read the data as I don’t have the exact register and the address which is responsible for that data , even the manual doesn’t mention it . Is there a way to find it ? I have the name of the chip .
