Hi, welcome to the family

Ttechielew well done! How long did it take to get provisioned?

BenCos18•3/15/24, 5:18 PM

well just got back home
seems the board has decided to die
fml

BenCos18•3/15/24, 5:25 PM

hmm seems it was the brand new cable only lasted for two uses

This could be due to insufficient disk space

Hi fellow devs,
I'm writing an article about OLED displays. It's a simple article with practical examples on how to drive an OLED display with an Arduino board, A Nucleo board and - last but not least - the 10-cent RISC-V MCU from WCH.

The article is still in construction. You can find it here:
https://embeetle.com/#blog/oled
I'll also post it on the DevHeads server once it's ready.

kristof-at-embeetle•3/15/24, 10:42 PM

kristof-at-embeetle•3/15/24, 10:42 PM

I'm looking for co-authors. If you've got a working OLED display sample project with an MCU-board - please contact me.

kristof-at-embeetle•3/15/24, 10:44 PM

I can then add your sample project to our Embeetle database - such that people from all over the world can download your project. Of course you'll get due credit in the readme.txt file

I may have figured it out possibly, i had to create and mount 3 different partitions for root, home, and the efi boot so we will see

Good day guys, I am running a program on Arduino IDE while utilizing Adafruit ESP32 Feather MCU. I have three sensors reading data thrice per run, with a 4G connection to transmit data to the SIM carrier's cloud database (likely on Azure). Additionally, I manage a buzzer and LEDs for device status indication. Do I need RTOS for task scheduling? Any suggestions to enhance or improve the device?

Marvee Amasi•3/16/24, 7:02 AM

Hmm building a mobile application sounds interesting @aymen ammari . Just asking , what would be the key features of the app, and how would it enhance the user experience compared to traditional methods of device control and monitoring?

aymen ammari•3/16/24, 7:04 AM

Hmm good question

Umesh Lokhande•3/16/24, 8:09 AM

The need to use RTOS is based on many factors considering your project requires managing multiple tasks. I'd suggest the use of RTOS in case you're already comfortable with porting RTOS on MCU. Otherwise, you can implement task scheduling without using RTOS to keep things simple

Marvee Amasi•3/16/24, 8:34 AM

Thanks for the insight too @Umesh Lokhande I'm now weighing the pros and cons of using RTOS, especially considering the complexity of managing multiple tasks. I'll try out both options further to determine the best approach for task scheduling in my project. Do you have any recommendations or resources for getting started with RTOS porting on the MCU?

RTOS for task scheduling ensures timely execution of tasks based on their priorities

Introduction to RTOS Part 3 - Task Scheduling | Digi-Key Electronics

The RTOS scheduler decides which task to run on a recurring basis, and some tasks can interrupt and run before other tasks in a process known as “preemption.”

The solution to the challenge in the video can be found here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-3-task-scheduling/8fbb9e0b0eed4279a2dd698f02c...

Hi everyone PLZ what is the solution to this problem? The ATmega32 is not the first time I've used it but i haven't written anything on it, just a (read )operation.

Navadeep•3/16/24, 3:35 PM

High level, the chip is failing to power up:

Do you have a voltage setting jumper in the programmer? Check it and set to 5V if you're using a lower level.
Power both Vcc and AVcc with the same level(recommended even if you're not using ADC)
Connect to all the GND pins
Physically verify the pin voltages
Just noticed, also the RESET is active low - meaning it's state should be held high to keep it in operating mode. Verify if that's happening.

Umesh Lokhande•3/16/24, 3:41 PM

Hi, @Camila_99$$ from connections it seems to me you're powering ATmega32 MCU from ISP programmer. I'd suggest powering AVR from an external 5V regulated supply possibly using breadboard-friendly LM7805. Often I found that these ISP programmers are not good at providing 5V to make uploading work
