Re: Making a USB compatible sensor

How would I make the sensor recognizable by USB and work with the Raspberry Pi system? Wire it up to something like an Arduino, Blue Pill, ST Nucleo, DigiSpark etc... You'll need to write the code still though. Otherwise try wiring it to the handshaking lines of a USB to serial chip like the FT232R...

I'd want to be able to plug it into my laptop as well.

I'll see what I can do...

Making a USB compatible sensor

Hi everyone, I'm very new to Pi, I've been making some camera sensor hardware that I would like to make compatible with USB and then connect it to my Pi to gather simple data. The sensors are basically 38KHz break beams that, when broken send out a pulse. Currently the system is employed to work wit...

Re: LCD screen cutting off windows at the bottom

Yes, it does work! In future, would there be a way to keep the popups small enough or is it a feature of this LCD resolution?

Thanks

LCD screen cutting off windows at the bottom

Hi everyone, Brand new to Raspberry Pi so you may see me asking a bunch of questions here. My problem is with the 480x320 touchscreen. I'm running the latest Raspbian and everything fits in to the screen until I try to unzip a file for example. The bottom of the popup windows will be somewhere off t...

Re: HDMI input for pi 4

Thanks,

The idea was to create a bundle of data, I need an image to allow for cross referencing the image in that bundle to a full resolution image that is on the camera. So I need both.

I find it odd that there are 2 HDMI OUT ports instead of one in and one out.

Re: HDMI input for pi 4

Older Pi models had hdmi input boards that could be integrated?

What about a HDMI to USB adapter that works as an input? Would that be a solution?

Thanks

HDMI input for pi 4

Hi everyone. This is my first post and I am looking at using a pi 4 for wildlife monitoring, combining ultrasonic samples with images from a hdmi connected, sensor triggered dslr as required. My thought was to get screen captures from each sensor trigger event to assist with matching up images. How ...
