Infineon Dave IDE - Ethercat Dev Kit V2.00 userbuttons in code

daemoninformatica — Wed, 07 Oct 2020 19:04:05 GMT

Greetings,

As I was selected to Roadtest the Infineon Optiga Trust M product, I'm currently in the process of writing, adapting and otherwise messing around with examples and materials published by Infineon and others.

As suggested in a lot of documentation, I'm getting aquainted with 'Dave IDE' and while I think I'm getting the hang of using Dave APPs, something is frustrating me:

The Dev-Kit has, besides the controller and a debugger interface, several other connectors (Arduino compatible shield and some headers) and a couple of buttons and leds.

Just about everything relevant is either coded in the silk-screen on which port and pin they're mapped, or this can be easily reverse-engineered from the schematics available.

Working to build a well-founded understanding of the technology, and following some steps I've set out to achieve in my Roadtest, I realised I needed to get some grasp of the method of working with the APP component system.

The 'getting started Blinky' over PWM is easy enough and answers some questions. But I all to soon ran into the problem: It seemed to be impossible to use one of the on-board leds (on the devboard) for the project.

Neither one (connected to P4.0 and P4.1 resp.) was mappable in the pin configurator. Fair enough, other pins were and those mostly were exposed over the Arduino interface. I wouldn't be much of a tinkerer if I didn't

have any leds in store (I could light a runway if I wanted to) so I had a blinky after that.

But deciding that I needed to continue experimenting on it and decided to add a button that would halt and continue the blinky by pressing it. Button 1 seemed a good idea so, as a true embedded engineer

(XMega, mostly) I decided to query the APP repo for an interrupt routine and work from there. How (much) hard(er) could it be? A simple Interrupt routine component is available, but when I tried to configure it

to use 'Button 1', it wouldn't allow me. Mapping it to P0.7, no problem and that basically worked, but I couldn't figure it out.

Adding the component Digital_IO and then using my (otherwise doing nothing) main-loop, I was simply able to poll the button state and update my PWM instance.

So mission accomplished, but I feel I'm missing something important.

Why was I not able to map the user-led in my PWM component?
Why couldn't I configure my button on an interrupt?

I found a datasheet https://www.infineon.com/dgdl/Infineon-XMC4700-XMC4800-DS-v01_01-EN.pdf?fileId=5546d462518ffd850151908ea8db00b3 about the pinout of the XMC4800 (starts at page 30) and while it has a Lot of pins, for example P2.2 (used for my PWM output) and P4.1 (The led I couldn't map) have very few distinct differences. But P2.2 has CCU peripheral connections P4.1 doesn't seem to have. I suppose that could the be reason for PWM limits?

But I have less success with understanding the Interrupt limitations. What symbol in the table denotes this one?

I'd appreciate it if anyone has any insights..

Kind Regards,

Martin.

What's Your Biggest Challenge In Implementing Motor Control In Projects?

rscasny — Wed, 09 May 2018 19:12:02 GMT

We have a lot of motor control content and projects around the community. To make sure we are putting up the right kind of motor control content or offering the right kind of motor control projects, I want to ask everyone about their challenges implementing motor control, drives, etc. Please add your comments below. Thanks.

Yes, as dougw says, driving BLDC motors is a whole different ball game. Simple stepper motor/ brushed DC is easy, but BLDC is a lot more complex & is a step above the level of most hobbyists projects: from basic trapezoidal, to sensorless and field oriented control, there is a pretty steep learning curve to learn the theoretical concepts. Implementation is another challenge in itself because the hardware needs to be exactly to spec when dealing with FOC since the whole system needs to be tuned. Sensorless trapezoidal is more flexible in that sense because it's more plug & play friendly.

Vendors are certainly trying to make it easy by doing most of the hard work for you, behind the (TI has InstaSPIN & InstaMOTION, ST has their own motor control SDK for STM32 & I'm not sure about Microchip & Infineon) but more content on the community that focuses on the technical side of things (deep-dives, webinars etc) would be pretty nice to have!

Sadly, I missed out on the TI Motor Drive Bundle, MotorWare, Personal Trainer road test, but something along the lines of this will be great! I was going through the reviews, and not only did they get a complete kit to test (C2000 Launchpad, Driver board & Motor), but they got a personal trainer from TI, which is definitely a step ahead of searching for answers on the TI E2E Community Forum.

BLDC, PMSM, trapezoidal BEMF

Motor control has increased in complexity since I was in school.

I have trouble justifying adding a lot of complexity to most motor projects.

importing alltium symbols to eagle

sushmithaborkar — Wed, 06 Sep 2017 10:24:29 GMT

Hello Sir

Am working on conversion of PCB components into different tools. I would like to know when importing altium footprint into eagle board ,the copper shapes such as solder mask layer and paste mask layer is not properly imported and PADS are changed fro rectangular to oval shape. Is there any solution to import it correctly or any script based on it.

Regards,

Design of three-phase Inverter for research purposestt

Former Member — Sun, 15 Mar 2015 13:19:56 GMT

I want to design a three phase inverter using the components from Infinieon. I want you to recommend me IGBT modules and gate drivers that are compatible with them to purchase from Farnel1

I suggest

INFINEON FS50R06W1E3 IGBT, LOW POWER, 600V, 50A, EASYPACK

with

INFINEON 2ED020I12-FI IC, IGBT DRIVER, DUAL, PG-DSO-18-2

are they compatible, also what else do I need to build the full inverter system, please recommend me with the whole staff to build this system with components from Farnell.
