I have to admin, that before I started with MCU programming, I fooled around a little with the Lego Mindstorms RCX 1.0 controller (got it cheap from eBay). But I got frustrated fast by the graphical programming language ;-)
Great video. Very informative. Needed a sensor for a project we're doing that can measure angular position. I think this might be what we're looking for.
Thanks for the praise :-) And good luck with your project! Since these A1335s are obsolete you can get them comparably cheap (DigiKey still has over a thousand in stock).
To be honest, I've switched to the A1335 (first video here: ruclips.net/video/b_1zqg0UZw0/видео.htmlsi=NmtvX_GhS9B3JnpM ). I'm using the internal correction table/mechanism of the A1335 nowadays ( ruclips.net/video/E37hL-k9jiY/видео.htmlsi=29HiJuzEU3BNqFS4 ).
Thanks! And I'm sorry, but I didn't buy any A1334 modules. I bought naked chips (from digikey.com) and soldered them onto breakout boards (together with the necessary decoupling capacitors and the flat flex cable attached). As far as I know no A1334 modules are available (besides some $100 evaluation boards from Allegro).
@@ud4458 I started using the A1335 (in production) some 5 month ago ( ruclips.net/video/b_1zqg0UZw0/видео.html ). Meanwhile I've written a quite capable A1335 library. Just search for all the A1335 videos on my channel. Though, it's not exactly a chip for beginners. You do have to solder it yourself onto a breakout board.
I need a similar sensor type, but in my case, the start will always be in a different angle, and i need it to know the position even when offline. Similar to absolute encoders, any suggestions?
Well, that A1334 does give you an absolute angle between 0° and 360°. So it is an absolute (magnetic) encoder. But what do you mean by "need to know the position even when offline"? The A1334 measures the angle of the magnetic field. So when it's powered up it doesn't need no zeroing etc., it immediately delivers the (absolute) angle of the magnet(ic field).
@@normiekl4532 You're welcome! I just wasn't sure from your first comment what you needed/wanted. So I felt compelled to point out that the A1334 is suitable 😉
At Digikey.com - but the A1334 is obsolete and meanwhile out of stock. See my videos about the A1335 for an active and available part. Here's the first one: ruclips.net/video/b_1zqg0UZw0/видео.html There are a lot more "The Details" videos. Just Search my channel for A1335.

MCU's and Lego what a great Sunday morning ! very cool stuff I look forward to next week to see the software....cheers.

Helpful video
You're welcome!
Hello, thank you very much for the good video. I use the Infineon TLV493D-A1B6_3DMagnetic sensor. What is your approach to off-axis correction ?
To be honest, I've switched to the A1335 (first video here: ruclips.net/video/b_1zqg0UZw0/видео.htmlsi=NmtvX_GhS9B3JnpM ). I'm using the internal correction table/mechanism of the A1335 nowadays ( ruclips.net/video/E37hL-k9jiY/видео.htmlsi=29HiJuzEU3BNqFS4 ).
Thank you 🙏

Hey rob great video! Can you please put a link to where you bought the a1334 modules? I cant find them on ebay

@@robertssmorgasbord would there be a suitable alternative chip to use? I am a beginner.

@@robertssmorgasbord thanks for the info , i totally understand that i need absolute encoder for that not an incremental encoder .thanks
