Thanks so much Teacher William ,

I enjoy and learn a lot .

Iron

Good overview.  Would like to see market share data tho it was alluded to in audio presentation.

Very interesting discussion as to vendors and choices

I dont really have enough exposure of dealing with 

micro vendors to give any feedback

like LPC2364 and small and cheap PHY, but price, complicateavity, size on PCB was higher then single chip solution.

Iron

on irony we were going to use NXP + PHY :)

Iron

@DaveWR Tank you for info about Stellaris M3 NRND - I'm using Stellarris too (LM3S9B95) due integrated Ethernet Phy. Not good news but they (TI) tells about adding Ethernet Phy into M4 in near future.

Iron
somewhat new info for me
Iron
Thank you alot, nice presentation.
Iron

Hi 

Does anyone has ST Microelectronic, NXP , TI roadmap for their microcontroller / processor. Thanks

Iron

Thanks Bill and Jinnifer, great presentation.

Iron

Question: Are any other high-level languages in use? I can understand assembly (understand, not like!), but C is old and from a software engineering point of view, very out-dated and outmoded.
 
Answer: Well, C is the most popular language for embedded developers. I think it's popularity will guarantee that it will be around for a very long time. You will find some manufacturers also support C+ a nd a few even support Java.

I think the biggest thing for us in considering whether to switch vendors is weighing the power of the development tools and the features that are available against the cost of trying to switch and getting trained on the new product as well as continuing support of existing controllers.
Brandon
 
This is important feedback, thank you!

Why change micros?  There is no one reason usually.  It's a weighing of all the factors and what you are looking for.
As always the application dictates.
RMRSS
 
Excellent points!

Question:  I don't see C as "outmoded". It provides a good mix of low level bit and register access with higher level libraries. Its generally a very good fit in the microcontroller application space.
JimWagner
 
Answer: I agree, I think the C language will outlast the planet!

Question: As far as choosing between different manufacturers for an application, would you recommend asking that manufacturer/vendor for "referrals" from other customers who might have done similar work?
Alaskaman66

Answer: Yes, it's always good to ask for referrals if they are new to you. You can tell a lot about a vendor that way.

Question: We currently use Freescale for thier ColdFire product. We are currently looking on going to an ARM product in the near future. When we do this, we will look at other vendors ARMs as well to see what they offer. In general we look for several things in a vendor - 1) are they on our Preffered Parts Vendor list. 2) How well they support their product (do they keep use tuned to new and better products coming down the pike) 3) Do they good development tools. and 4) how much can they help us out when we get into trouble if we run into snaggs during devlopment.
johnmr

All excellent criteria. This keeps you out of trouble and teaches you a lot about the vendor.

Question: You didn't say much about those mixed-signal devices that have both DSP and MCU cores.
JimWagner
 
Right. These tend to be in a very specific niche of applications. As I mentioned, microcontroller people tend to shy away from anything that says "DSP". But some of these hybrid cores, like the Microchip dsPIC, are very powerful devices for motor control and sensor processing.

Was not able to log in yesterday, so I just finished catching up. Looking forward to today's class.

Question: Re: development boards... It appears one can tie up a lot of $$ buying several types of development boards. Are used dev kits available? Will a vendor let you use a low level board for testing an application, then do a buy back for a more advanced dev kit?

I haven't seen anyone provide used development kits. One problem with a used kit is that you may not be able to determine if it is damaged. You might try contacting your local representative to see if they will loan you a board. Digi-Key does offer development kits at very low cost.

Question Which vendor as of now do u consider has the best/extensive code support or examples ?? for 8 bit microcontrollers?

Any of the major 8-bit players – Microchip, Atmel, Renesas, ST – will want to provide excellent code support and examples for 8-bit microcontrollers. These are the 8-bit companies that have done well during the 2008-2010 "recession" BECAUSE they were focused on 8-bit. That focus kept their 8-bit biz alive.

Iron

Question: Are there any 64-bit uC or do you forsee one in the near future?

Cghaba

64-bit architectures are really in the realm of the microprocessor. Very few microcontroller applications would require that sort of number-crunching.

Question: We're working with some educators advancing STEM in middle & high schools. Do you know of vendors who share that emphasis and have development boards focused on that level of study?

Most vendors have educational programs and are happy to supply schools with hardware at reduced cost.

Iron

Question: With repspect to roadmaps, for a long time, Atmel only released road-maps to preferred customers. Maybe this is still their policy as I've never seen one publically available. For me, rather than forcasting the future, I use them to see how the manufacturer concieves of the relationships among their products and what the potential upgrade paths are. Having the roadmap makes the system designer's life a LOT easier, even if you are a small customer.

JimWagner

I agree. It is unfortunate that roadmaps for future products are often kept confidential by many microcontroller vendors. However, you can still judge the feasibility of a microcontroller product line by looking at a roadmap of existing products.

Questions in italics

Bill Giovino responses

A generic question. I havent seen a microcontroller so far with 2 usb modules. It would be really good if i can use a microcontroller as a usb device as well as a usb host at the same time. Is there any in the market now ??

natraj20

STMicroelectronics, Microchip, and Atmel all offer microcontrollers with two or more USB ports. Check them out!

Iron

Welcome back from 3 day weekend, everyone.

Thanks Bill, looking forward to the week. I tend to only change family or architecture at the beginning design phase of a project. Unless something goes horribly wrong of course...

Iron

Due to to TI NRND of M3 Cortex am now looking at ST Micro STM32F4 line -- M4 Cortex.

Iron

Texas Instruments has issued an NRND for the Stellaris M3 line. They want you to use M4 -- however nothing with Ethernet -- no high speed clocks in the four chips (sort of) available now. Go to their e2e forum to get details.

 

Iron

Was not able to access your site this afternoion from Ontario Canada.

Catching up

Iron

interesting good info

Iron

Better late than never

Iron

Yea, It'll work tomorrow.

Iron

Did I get this fixed?

Iron

As far as choosing an MCU for some application, do you think it would help to discuss the sensor suite and user interface with potential vendors, and let them recommend product (lines)?

FOLKS, BILL HAS LOST CONNECTION, BUT WE WILL BE SEEDING ALL OF YOUR QUESTIONS, AND HE WILL DO HIS BEST TO ANSWER ALL.  THANK YOU!

That is tough to answer. A lot depends upon your local sales office. I see strong support from Microchip, ST, and Atmel and Renesas. These are the 8-bit companies that have done well during the 2008-2010 "recession" BECAUSE they were focused on 8-bit. That focus kept their 8-bit biz alive.

Nice intro. It confirms that the support system is very important to the decision.

Thank you.

nice presentation.  i try to stick with microchip as i'm used to it.. but if for some reason, i do not get all the hardware peripheral features i need (eg: usb, 2 mssp and 5 pwm all in a single package) i would try to switch to a different vendor 

Iron

Where can i pick up the archived audio? i have got issue with audio even if the players loads.

Excellent overview, Thanks Bill

 

Blackfin processor family is unique in its ability to bridge the gap between microcontrollers and DSPs.  Also has excellent DMA capabilities to move data to and from peripheals/memory.

Which uC is best for educating students in uC practice?

Iron

Thank you for today's presentation Bill

Iron

Thanks so much for your time, William.

Iron

The 8051 core intellectual property is available inexpensively on license.

 

Iron

out of all the vendors u listed, what do u consider has the best code support or extensive library support ?

 

Iron

Can you expand on development boards and their key to MFR commitment?

 

Iron

Bill, your lecture sounds like a high level marketing "guide to success" for a MC vendor...

Iron

One difficulty we have is that we have a history using a certain type of microcontroller, so there is a lot of legacy code that is reused/leveraged in new products.  I'd like to explore other vendors - do any of the development tools help with porting code between various microprocessor vendors?

 

Iron

Does Intel make any 8051s anymore? It seems like everyone except Intel makes them these days. 

Many still use assembly, but C is valuable for quicker development and also if you work with multiple vendor products.

Iron

oled is also a modern display option

Iron

Is C really the only or the most predominant language in use? What other languages are popular?

Iron

@cmpatel - 8051 by Intel is quite popular...

Iron

Does intel provide microntroller? If yes, why it is not popular? 

Iron
