Simple, like arduino, only much faster. What?

Question

Arduino

In general, I like Arduino because I am far from electronics and programming can quickly do what I need on it. And it helps me solve some tasks quite easily. But ... When there are many of these tasks, then there are two ways out. Either a few arduins or ... something much faster. And it is desirable that this something could be programmed as simply as an arduino. But what would work many times faster. What do you advise?

PS To get confused by programming chips at a low level will not suit me.

Answer 1

Raspbery PI
STM32 Discovery
There was also some kind of arduino on the arm. Yes, thousands of them. The only question is how fast you need and how hard you are ready to climb there.

Answer 2

MSP430 LaunchPad
The MSP-EXP430G2 LaunchPad also comes with 2 MSP430 device, with up to 16kB Flash, 512B RAM, 16MHz CPU speed and integrated peripherals such as 8ch 10-bit ADC, timers, serial communication (UART, I2C & SPI) & more !
Price now 9.99$

Answer 3

If you need port speed, discard the library and work with ports directly.

Answer 4

I propose to connect a single-board computer ($40-100) to Arduino Mega (more pins) via usb, for example, and organize all the logic on it. But in terms of programming, it will be a little more difficult. But in general, there are plenty of manuals for the same python, for example, including its work with Arduino.

Answer 5

Here the question is - what exactly is speed needed for? RPi and other Linuxes are usually not real-time, and cannot respond quickly enough to events, for example, read position sensors and control copter motors. And if you need to process a data stream, for example, then, as they said above, you need to hook up an arduino to any single-board computer - RPi, cubie, beagle, etc. Whether you need floating-point math or integer math is enough, or suddenly you want to run opencl, it all depends on the task.
On the topic, if you do not think about the goals - Arduino Due, there is still SAM3X8E ARM, which are faster than 8 bit avr.

Answer 6

PLC?
Some DirectLogic, for example, or the weakest lines from other manufacturers ...
With a separate motion control module, you can find it.
But it will be much more expensive.
