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!

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 .

What's the chip

Ttechielew What's the chip

Accur4teOP•6/20/24, 6:12 AM

atmega 16

Accur4teOP•6/20/24, 6:12 AM

i dig the info up - i got exact value of the register yet , arduino is unable to retrive info

Accur4teOP•6/20/24, 6:23 AM

0x4001 to 0x4003 ---> flow rate value
0x4004-->flow rate value unit
0x4005 to 0x4007 -->totalizer value
0x4008-->totalizer value unit

Accur4teOP•6/20/24, 6:23 AM

irst digit is data bits which is 8b
Second digital is Parity which you select as N for None, E for Even, O for Odd
Third digit is stop bite which you can select as 1 / 2 bits

I use the ESP32 Wroom module in developing my project, when the program code is run the gas sensor that I use always gives the output "MQ135Status: 0". I don't think there is anything wrong with my code, is this related to the esp32 module that I use?

as per the error code , there is problem sensor reading or communication - check wiring , lib use , or trying giving 5v vcc if it supports and do use a analog pin for sensor data .

Accur4teOP•6/22/24, 2:18 PM

Hey everyone, I need some advice. My dad, who's a businessman in the flowmeter industry, thinks the two projects I've been working on for the past 3 months are big steps and that I'm trying to skip some steps. The projects are an ESP mesh for flowmeters and an electromagnetic flowmeter. I agree with him to some extent.

I'll be joining my second year in ECE college in the next few days. What do you think my next step should be? Should I try to get an internship in a business related to IoT (my field of interest), or should I focus on learning more theory? I already have 7+ years of experience with electronics (mainly Arduino, ESP, and Raspberry Pi) and recently finished learning Embedded C. I genuinely need help deciding. I'm really passionate about electronics, especially IoT. Thanks!

Umesh Lokhande•6/23/24, 6:34 AM

Not sure if I'm the right person to answer. But if I have been at your place. I'd have preferred to engage in an internship to gain more technical hands-on experience with professional tools used in embedded & IoT. All this is to be done along with academic studies.
