Arduino vs Microprocessor vs Microcontroller - Electrical …
2018年4月27日 · Arduino is a microcontroller based platform (ATMEGA 328 for the UNO). In general a Micro-controller is better suited than a microprocessor to anything the requires sensing of inputs. That's because micro-controllers like the ATMEGA 328 have analogue to digital converters (ADCs) to sense voltages and also have PWM outputs as well as digital I/Os.
time - Arduino Due precision with function micros - Electrical ...
The Arduino Due uses an Atmel SAM3X8E microprocessor. It has 3 identical Timer-Counter peripherals, each of which has 3 independent timer channels. On the Due, these are the best way to measure small amounts of time if you want resolution in nanoseconds. Each Timer-Counter can use different clock sources as input - these determine the ...
How to graduate from Arduino to using a microcontroller directly?
2014年3月1日 · Since you have an Arduino, you could save a little money and use un-programmed chips, using the Arduino to install the bootloader. The nice blue pin-out labels help keep my goof-rate down! I use a 16MHz crystal but if you can run with the internal oscillator your parts count goes down by 3 (the xtal and 2 capacitors).
What are some "professional" arduino alternatives? [closed]
E.g. the Arduino Uno R3 has an Atmega328P MCU, a very simple 8bit type from Atmel (now Microchip). The PRO tools give you some really nice features that are not provided in the Arduino ecosystem, like e.g. single step code debugging, code and power profiling, virtual ports and a …
What's the difference between a microcontroller and a …
MicroProcessor - Does the 'thinking', is basically is the chip itself which handles math. Microcontroller - A system with a microprocessor included, readily capable of interfacing with electronic components for developing embedded system. (Think arduino, PI, PSOC4 etc.
floating point - Arduino Mega/uM-FPU coprocessor - Electrical ...
I recently acquired a number of components including an Arduino Mega microcontroller and a uM-FPU V3.1 Floating Point Co-processor. Using a breadboard I have built the circuit shown on Page 2 of the document uMFPU-V3_1 Arduino.pdf from the Micromega website. I am having some difficulty in getting the circuit to function as expected.
Advantages of 32-bit 48-96 Mhz microprocessors (such as in …
It seems Arduino Due ( 32-bit, 84 Mhz, ARM-Cortex-M3-based SAM3X8E ) was released today.. In addition, clearly there is a myriad of processors in this category ( 32-bit / 48-96 Mhz / ARM ) as well as corresponding prototyping boards:
Which programming languages are supported to program Arduino?
2011年4月28日 · Of course the arduino can run any language there is a complier for, but it can interpret any code that someone bothers to write an interpreter for it. I have not researched this. I just recommended sticking with the standard c/c++ enviroment, and noted that with communications the pc could run a "pc language". \$\endgroup\$
Arduino and Intel 8255A-5 interfacing
2013年7月27日 · The 8255 is designed to interface to a microprocessor that has an external memory and I/O bus, and it works very well in that environment. However, the Arduino does not have an external bus, so you are forced to emulate that bus by bit-banging individual I/O pins, which is slow and painful. Your code needs to generate pulses on the RD, WR, and ...
arduino - Filtering Reverse voltage from a coil - Electrical ...
I am going to tap into the input voltage for that coil and hope to convert to DC, trigger a relay and send a signal to the microprocessor to enable me to "watch" the scoring on the pinball machine with the arduino processor and control some LEDs (shown bottom left). All the circuit stuff (but for the 26 V AC coil) are in a project box.
