Hi, I want to make a circuit to collect the temperature of some locations in a control panel. I have a control panel that is connected to several microcontroller circuits. Each microcontroller circuit measures its ambient temperature. the control panel sends a number from 1 to 20 for example...

Hi all, I've been having a very big problem since 2 days. I got a brand new Atmega328P U-TH IC and made a custom board around it. Due to covid lockdown I am not able to purchase any programmers like USBasp, so I decided to use my Arduino UNO as ISP programmer. However, When I tried to burn the...

libvmcu - Virtual MCU Library libvmcu is a library for static and dynamic analysis of AVR binaries. It can be used to create regression tests for embedded systems or to analyze AVR programs on assembly level. You can build your own tools too. There is also a Java binding, that supports...

HI everyone! First of all: I am using standalone Atmega32 (no arduino or such), Eclipse and C language. I been troubled with this for a while now, I looked thru lots of forums and sadly couldnt make it work. Right now my best idea is working on a sample project from...

Hi there! Does anybody known how to code an interrupt driven driver using Microdevt toolkit (www.kw-net.com) ? I am trying to develop a simple driver on my atmega328 that enqueues a bitstream from an other uC. The bitstream is read on an input pin and then processed if a certain amount of data...

Here is a part of my schematic. K pin from LCD is connected to NPN transistor. A pin is connected to Rc and Vcc, 5V. Base is connected to uController. It is Atmega16. 5V supply. I am using 2N3904 transistor as it is showed at the picture. Electrical Characteristics form datasheet: Vcbo= 60V...

Hi, I'm new to microcontrollers and I'm trying to build this 4x4 LED cube, controlled by an Atmega16: https://www.instructables.com/id/LED-Cube-4x4x4/ I've completed the circuit as shown in the tutorial and am testing the output pins before I put together the rest of the cube. When I set the...

As I'm a new microcontrollers student, I read in a book that in ATmega168 the hardware register for Port B is at byte number five of the memory. And I downloaded the datasheet and kept searching for this in the "pin configuration" section, but I could not figure out where to find this specific...

Hey Guys, I just wanted to share with you a project in order to get some constructive feedback. MDX is an Assembly Simulator for 8-bit AVRs. It has an integrated Disassembler, which reconstructs labels and comments in order to increase readability. What's different ? - Backstepping is...
