Feb 17, 2014 · Arduino: For beginners like me, Use an appropriate sized arduino for the project; AVR, ARM, etc: For professionals, better for projects that need to look professional and such; Am I correct? Mostly. The ATmega328P microcontroller in the Uno is an AVR microcontroller (MCU). The Arduino IS a microcontroller. If you mean a bare chip, then you will ...

Jul 24, 2012 · With the release of the Leonardo recently, we see the Arduino team's choice of going with the ATmega32u4 as a much more superior and cheaper alternative to the Atmega328 for various reasons which I won't go into here. While I agree with most of the reasons, my one main gripe with the choice is the fact that the microcontroller is an SMD as opposed to a through hole. Here're the problems that I ...

Dec 26, 2018 · This is an Arduino forum, so the answer is "Duh, AVR all the way man!" And there are reasons for that. Since Arduino, the microcontroller world has become flooded with AVR code. PIC was the platform of choice in undergrad microcontroller classes for years, but even in this dusty hallway of technology, AVR is making headway.

Jul 16, 2013 · There are details like cache, CISC vs. RISC, SIMD vs. MIMD and Harvard vs. von Neumann, real vs. virtual memory etc, but that's pretty much all there is to it. system July 17, 2013, 2:31pm

Feb 13, 2018 · I very often get the question that what is the difference since both the microprocessor and microcontroller looks same. One of the main difference between microprocessor and microcontroller is that the microcontrollers are designed to perform a small set of specific functions, for example as in the case of a Digital Signal Processor which performs a small set of signal processing functions ...

Dec 19, 2008 · However, your "new 555" comment serves to point out some of the weaknesses of modern microcontrollers as well. The original 555 runs off supplies from 4.5 to 16V, and supplies (or sinks) up to 200mA of current on its output pin. The inputs are as tough as nails. You won't find that sort of ... sturdiness in a microcontroller.

Oct 23, 2014 · I'm using an Arduino Mega with an adafruit datalogging shield and microphone. I also have a Raspberry Pi and I have a small amount of funding to buy a different microcontroller or shield if necessary. I am currently using this code, which is just a slight adjustment to the ReadAnalogVoltage example sketch: int ind = 1; void setup() {Serial ...

Dec 15, 2014 · Arduino vs. PIC. I've never used the PIC in a hobby project. But where I work we have a couple of PICs in our products. One of them (I think it' 8-bits) is just basically being used as a bootloader, and the other one is the main processor in the product (I think it's 32-bits). The things that attracted me to the Arduino: It's on a board.

May 1, 2011 · The bootloader used is reflected in the boards.txt entry of a specific board selection and tells the IDE the baudrate used for the bootloader as well as the memory size and the fuse and lock bit values used. The pins_arduino.h file is where one defines the abstracted arduino pin numbers to the physical port.pin numbers of the chip. Lefty

Dec 20, 2012 · Hi all, Having completed a good number of successful projects with AVRs and the Arduino IDE with a large number of I/O etc - I find it strange that I'm asking a question, to which I still don't truly understand. What really, is the difference between an 8-bit MCU, a 16-bit etc etc? All the resources seem to point to PC related arguments of 32 vs 64bit processors. Most pages simply state larger ...
