Microchip-Farnell Low Power XLP Webinar

Hi Friends,

 

I have attended this day Microchip-Farnell Low Power XLP Webinar. I found it very useful and informative.The sound was so much clear and easily understandable. I have never faced any broken line during the presentation. Webinar continued 1 hour or a bit more. I had some information about XLP technology of Microchip but this webinar helped me alot about understanding it a bit more in detail. I had a project called "Temperature and Humidity Controller and Logger" which was unexpectedly postphoned and is waiting for a touch. I had used a normal mcu for the "remote sensore" but carrying the power to a remote location was really a big problem. So i started thinking of using an XLP mcu for this part of the project.

 

Anyway, i would really like to know the other attendees's thoughts about this webinar and the projects of both the attendees's and other members's that have already finished or currently in progress or need a touch.

 

In the meantime, even though this webinar was fully satisfactory, i would like attending a live seminar where i live ( as a country ). Because, on the phone, you may miss some parts and it may be very difficult to ask a question if you are really not there. Yes, off course this case is just for me. I don't know what the others say about this.

 

Microchip's XLP technology is wery exciting and promosing. I carefully fallowed the numbers about power consumptions of the modules in both sleep mode and deep sleep mode. But there are other criterias for a proper energy harvesting application. You may choose the best low power mcu but if you did not design a well pcb or/and your software is not written so well then you are in deep of power consumption. A bad written code for an application may cause doubling or even tripling the total power consumption, the same is true pcb design as well.

 

For this reason, in my opinion, in such kind of seminars ( webinars ) a well designed XLP application should be explained with mcu and a pcb design and application sample code. It may be presented how a wrong pcb and software design cause how much power loss.

 

Maybe i am wrong. What do you say ?

    Hi Firat,

     

    I too was attending. Though at the start I had some hiccups, but later on was able to follow the seminar clearly.

     

    Microchip has put in all efforts to minimize the hardware power consumption by introducing features like deep sleep, and wakeup in shortest possible time. The example application 'Electronic Shelf Display', was also appropriate one. One has to set up priorities for any particular application ie. optimum refresh-rate, optimum brightness of display, etc. Maybe we can also have some sensor to keep the unit in deep sleep if there is no customers around, to further save on power.

     

    I fully agree with you that a wrongly written code itself may turn the unit into a power hungry application, offsetting the advantages offered by XLP devices. Given the same code, the Microchip XLP may definitely be most power efficient device available.

     

    I would add, an in-depth knowledge of the subject goes a long way in developing the most efficient system.

     

    Happy developing,

    Howdy,

     

    I'm not sure this is the correct group for this posting.  Maybe "Embedded Design", where the original webinar was listed?  But anyway the webinar was informational.  With the Q&A, it ran a little over (OK with me since I asked some of the questions).  I wish they had shown in more detail how they arrived at their battery life predictions.  Their life predicting software was interesting and useful, but again their formulae would be helpful.  In the wrap up, a summary list of app notes web links would have been helpful instead of just a link to XLP web site for more information.  At the end of the webinar, one of the presenters mentioned email'ing the presentation to the attendees.  Has anyone received a copy?

    Hi Gordon,

     

    Yes, this group is not the original group that the webinar belongs to. I Alistair had no announced it in this group, i could not be able to attend the webinar, because i would not know that this webinar was. Why did i post it here ? Because i wanted to know what attendees in this group were thinking about the webinar and maybe some knowledge about their projects with XLP technology which are running, currently in progress and/or still in design stage.

     

    I have seen you question about webinar presentation in documented form. But, till now, i have received nothing. I hope we will get it soon.

    Hi Thomas,

     

    Thanks for the information you have give. I agree with you, too I always loved Microchip. So mostly i use their mcu families. But for 32-bit family, i have no idea yet. I had bought a Pic32 started kit but have not reviewed it in detail. For flash programming, i need icd3 but it is a bit expensive and its cost causes a bit huge problem in the customs i am waiting for the right time.

    Hi everyone,

     

    thank you for attending our webinar. I will e-mail the presentation to all attendees tomorrow.

     

    If you need anything else, please let me know.

    Hello,

    the webinar was very interresting ! thank you very much

    FIRAT : For the PIC32 you don't need the ICD3, ICD2 and even pickit2 works with some minor limitation (speed, software breakpoints...).

    XLP uC series are ideal for use with solar cells. RTCC is great to use in measurement systems.
