That's too bad re: BLE being unreliable -- is the signal giving out? So cool. I had no idea these little retail things even existed, outside of the PI and Arduino. Great list, and thx! I am an old fart 70 who has been messing around with Pi from when they were first available.
Yes I was one of the first to order the original Pi. I have now been looking at the Arduino robust hardware interface projects and Micro:Bit for a local community maker shop class.
Thanks for doing this presentation. That's so awesome!! Very happy to hear that you found this tutorial useful along your maker journey :D. I was excited to read your Instructable and was getting into it until I saw that you had to be 8 yrs. I am 69 and a 45 yr practicing engineer so there is no hope I can comprehend what you are saying. Ha, ur kidding no? I'm a year old retired IT manager, and I think I'd find anything on that list recommended for 8 year-olds challenging.
I think I'll find a teenager and give one a shot :. Reply 3 years ago. Nice introduction of the MCU's, but I expected more from this instructable. For example which languages you can use to program them - like Basic, python, C, asm, Pascal I've definitely changed the header of this instructable for something like "which microcontroller to use?
Good suggestions! I wanted to keep the writing to a minimum, on this tutorial, but I will add in the programming languages. Great tutorial videos on YouTube. Right -- there are more microcontrollers out there than one person could possibly keep track of. The goal of this tutorial was to provide an overview on the most common and easily accessible microcontrollers. Yes, it's impossible to know them all, considering the speed at which new variants hit the market.
For a hobbyist, it's better to just go with a few models, which also makes it easier to get good prices from large -ish orders. Buying e. The ever changing landscape of microcontrollers also means new programming chains if you look outside Arduinos and such. Around Win 3. Software can add multitasking to all but the smallest microcontrollers - just add a RTOS or build your software with State Machines for simulated or Time Slice multitasking and you even have multi-kernal microcontrollers that are born for multitasking The Propellor is an early-ish example , although I personally prefer to just add the amount of microcontrollers needed, to make both the hardware and the software handling easier and modular.

This is not just dependent on the raw clock speed; it also depends on the data width of the processor and any hardware acceleration features included. Microcontrollers for embedded systems mainly fall into three categories based on the width of their data buses: 8-bit, bit and bit. There are others, but these are the most popular ones.
In general, 8-bit microcontrollers are geared toward lower end applications, and bit ones are for the higher ends, with bit for mid-end applications. By far, most of the products I work on tend to incorporate bit microcontrollers, but 8 or bit microcontrollers can be a good choice for low-end, low-cost products.
If an application does not have very high demands on processing power, and is of relatively small size, then it can make sense to consider an 8-bit microcontroller. For reference, most Arduinos are based on 8-bit microcontrollers.
So if you have built your early prototype using an Arduino then you may be able to use an 8-bit microcontroller in your final product. For example, the Atmegap is the 8-bit microcontroller used the Arduino Uno. On the other hand, you can purchase a bit microcontrollers running at 48 MHz with similar memory for only 60 cents. This is likely due to the popularly of bit microcontrollers driving down their cost.
That being said, there are even cheaper 8-bit microcontrollers available that cost less than 25 cents at similar volumes. A minimal system can be as simple as a single chip, with a bypass capacitor on the power supply rail. Originally from Intel, and now made by others, this microcontroller is still in common use today, embedded in lots of appliances.
While they are available as standalone devices, the is now mostly used as IP Intellectual Property cores that are embedded in the silicon of dedicated application-specific chips such as some wireless radio transceivers. Very rarely would the be the correct choice to serve as the main microcontroller for your product. PIC microcontrollers are quite popular, and have wide support by both Microchip, and third parties. This can then be integrated in the application code.
Higher quality commercial compliers that have better code optimization are also available. The AVR is another series of very popular 8-bit microcontrollers. Due to the very wide range of available libraries for Arduinos, the AVRs merit serious consideration for 8-bit applications, even if only for proof of concept prototypes.
They are faster, support even more peripherals, and generally offer more memory, both flash and SRAM. In addition to more IO pins, most of them also have hardware multipliers that are significantly faster, and use less program memory, compared to pure software implementations.
Internally, these devices also have hardware blocks typically not found in lower end devices. Although bit microcontrollers can be found from various manufacturers such as Microchip their dsPIC33 is a popular choice , NXP, Infineon, or Cypress, the TI MSP series will be presented here as a typical example of this microcontroller segment. The MSP is a series of very low power bit microcontrollers that are available in many flavors.
They range from general purpose to very specialized models. One interesting thing about the specialized variants of these microcontrollers is that it actually branches out into two extremes: very dedicated, very low-cost models, and high end models with analog sensor interfaces and Digital Signal Processing DSP.
