Arduino for STM32

For me, it looks too complex. I don't like complex things.

capacitance? which sensor?

light intensity? which sensor?

what's the "remote function calling" mechanism mentioned on the Arduino presentation ?

ebay


Little OT/rant. I won't buy anything from eBay!

After 10 years and more than 600 positive feedbacks received as buyer and seller, I deleted my account there since I reported a lot of known scams to eBay without any result, and, worse still, I have a written email from eBay where they ...

they may not meet the 'industrial' requirements, hence u'd need to decide if you would play with those

yeah, I need 5mm of precision, but I don't know if the above dispersion data plot is really trust-able ...

just out of curiosity, has anyone ever hacked an already existing product like a "digital measuring tape" or built one?

Measuring with rotary encoder...


The suggested video shows a Measuring Wheel , and it would be a good idea if I didn't need a contactless measurement . I mean, I cannot add a rail just for the measuring wheel, and the only way I can have a rotatory encoder in a contactless measurement ...

VL53L0X lidar?


I don't know which is real precision of the VL53L0X, I tried the Sharp TOF10120 (SPAD, Single Photon Avalanche Diodes), which is ranging 100..1800mm, and ... well, it performs well in the 100..500mm range, but In the higher points, 750 and 1000mm, the readings are off by a great ...

This would require to open and hack the motor-box I am using in order to install the rotatory encoder, but I would avoid it because the motor box is sealed.

hi,
I am building a complex machine that moves a plane vertically and I need to contactlessly measure the position between two movable points that range between 600 and 1300 mm with a precision of 5mm .

I tried the some Sharp reflective IR sensors, but ... the voltage-distance curve is hardly non ...
