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 ammariOP•3/16/24, 7:04 AM

Hmm good question

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

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?

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.”

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.

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

Marvee Amasi•3/16/24, 9:14 PM

@wafa_athmani Your RTC has time keeping issues, try

Check connections: Ensure your RTC module is securely connected via I2C.
Check your power supply: Ensure stable power source; unstable power can cause resets.
Battery Backup: Check battery on RTC module; dead battery can cause resets.
Configuration also: Double-check RTC module and Raspberry Pi configuration.
Software Updates: Ensure your Raspberry Pi OS and RTC drivers are up-to-date.

Or try another Raspberry Pi or power source to isolate the issue.

I was ordering a PCB from JLCPCB with a size of 8cm*4cm, 4 layers board. When I placed an order for 15 pieces it came out about $20. But when I increased the amount of PCB to 20 pieces, the board price increased drastically to about 40 dollars. When I ask they said it's pcb panelization. How does this affect the cost. @PCB & Analog

aymen ammariOP•3/17/24, 1:31 PM

I think it's related to Copper plate that should enter the machine for manufacturing, 15 seems to use only one plate and for 20 they'll be using 2 of them and the second one the majority of it will be thrown as Droppings

aymen ammariOP•3/17/24, 1:32 PM

Try increasing the amount to 29 for example and it will stay nearly 40$

aymen ammariOP•3/17/24, 1:34 PM

In other terms :
PCB panelization involves placing multiple PCB designs onto a single larger panel for manufacturing efficiency. When you increase the quantity from 15 to 20 pieces, it might exceed the maximum number of PCBs that can fit on a single panel efficiently, requiring an additional panel. This can result in higher manufacturing costs, thus increasing the price per board. Essentially, you're paying for the additional material and manufacturing process required for the extra panel(s).

Joseph Ogbonna•3/17/24, 1:41 PM

Most times PCB fabricators do produce there PCB boards in panels which are of various sizes. When do do pay you pay more for the panel not just the design itself. So for your design the extra 5 pieces you added increased the number of panels. Let's say to two panels, which then increased cost.

Joseph Ogbonna•3/17/24, 1:43 PM

It's always adviceable to know how your fab house do there panelization and with you can determine the size of your board to the number of boards that will be produced to reduce cost

Flo•3/17/24, 8:09 PM

Hmm-- perhaps some kind of object recognition? Like point a camera to a tree/the sky and try to identify birds and planes? Or build a door lock for your room that only opens if your face is recognized (perhaps build some kind of second method for opening the door into it so you dont lock yourself out :D)

Flo•3/17/24, 8:10 PM

Is it that kind of suggestion you were looking for?

In a Zynq SoC, can we read data from memory while DMA is operational (writing)?

In my opinion, yes you need, maybe build a mobile application for it, and offline notifications and
