I guess it is true that we have to be sure about the processor according to our need and for that taking guidance is an excellent idea. Usually we just buy it according to the guidance given by the seller or the publicity conducted by the companies.

Great idea for a class and I think it's going to draw a huge number of attendees. All the things you mentioned are right on track, Rich, and power draw is becoming a big consideration, too.

I agree. MCU suppliers have a big handle in what type of processor to use based on their marketing strategy. Ultimate, the customer has to know the product they are desigining interms of functional requirements inorder to make the appropriate mcu choice.

Charles,

I agree. I'm teaching a microprocessor and microcontroller class at ITT Tech and one of the questions asked by my students is, "What's the right processor to pick for an embedded application"? Several items I suggest in picking the right processor where discussed in Rich Nass's article. A class on this topic will always draw a large crowd because of the DIY/Maker movement that's happening in the states and overseas. Developers and hobbyist are always interested in knowing how to get the most out of a microprocessor or microcontroller for their embedded projects.

I'll be presenting a CEC course on the Arduino scheduled June 9th - 13th. I'll be using some projects from my latest Arduino book during the course presentations.

Now this is exciting news - I have used PICs in a few projects and really like not only Microchip's amazing selection and a very well done web page for technical support - but they also boast a wonderful online community that has gotten me out of a jam more than once...and the programming tools are easy and intuitive.

Mrdon is right on target with his comment, "Ultimate, the customer has to know the product they are desigining interms of functional requirements in order to make the appropriate mcu choice" in that you have to understand the project so that you select the correct microcontroller for your application, including nuances that you may not think about when you first start out. This series of classes are a great idea!

Thanks for the comments and yes I agree that Microchip has a variety of good PIC MCUs to choose from. I'm currently exploring the PIC18F8680 microcontroller for future training courses and projects. Just wondering if you have tried their MPLABx IDE platform for developing PIC source code?

Hi mrdon - its been awhile since I messed with PICs although that is only because I have been involved in other things...I sure do like 'em! I started out with the old 8751 back in the day and have always had great affection for microcontrollers.


My last PIC project has been awhile - I used a PICkit 2 with the older MPLAB IDE (I would have to go boot up my old lap top to see which version it was) - and programmed in assembly - it worked like a champ. It required PWM which had a great deal to do with my MCU selection - it is onboard the PIC16F616 - very fun project! Hubby designed the hardware and I wrote the software which made it extra special.

Nancy, Do you prefer coding in Assembly? It is a great way to learn about the architecture and indepth functioning of an MCU but for me to fast up things I almost always shift to C.

I am currently working with STM 32 and TI HDK kit. Both of the are really good 32 bit architecture MCUs and both utilize ARM architecture. Specially, the compactness of HDK kit is really usefull. You get set up really fast on that and it comes with a Halcogen software which makes coding a whole lot easier with its configuration code.

Good point far911. What people mistake generally is that they over spec their MCU requirement with the fear of failing and believe the hype created my the market which costs them alot. It is very important to have the right knowledge about the requirements of the application along with its corresponding specs on MCUs.
