Proof of first low-level driver version :) 2 channels in ext. driven dither mode. Figure shows the signals & trigger. Working with device-driver by @diondokter.nl and Pico de Gallo by @balbi.sh is amazing! Working repo: github.com/trappitsch/l... See example: ll_dither_ext.rs #EmbeddedRust

Oscilloscope traces showing the output square wave (10kHz, 0 to 3.3V) and two input channels. Both input channels show sine waves. The first input 1 has a level of 2V and amplitude of 1V, the green input 2 a level of 5V and amplitude of 2.5V. The green input 2 is phase shifted with respect to the yellow input 1 by 90 degrees. Both inputs have periods of exactly 32 square pulses of the output.

My first real Pico de Gallo test: successfully set the voltage on an LTC2686 DAC. Development with Pico de Gallo is going to be very fun :) Next thing up: write an actual Rust driver with Device Driver v2. Thanks to @balbi.sh and @diondokter.nl for these amazing tools! #EmbeddedRust #Rust

Bottom left shows a Pico de Gallo in a case connected to a colorful ribbon cable. Some wires of ribbon cable connects to a LTC2686 dev board in the middle. Furthermore, various probes are connected to the dev board to supply the required voltages. A voltmeter on the right, which is connected to an output channel on the LTC2686 shows 2.499 V.

This week I received a Deimos DAQ Rev7 from @deimoscontrols.bsky.social It acquires precision measurement, here from two thermocouples, and can use these to control outputs, here a GPIO pin. All controllable from #Rust (or python). Thanks @ponderingpothos.bsky.social for all your help!

Spent the last two weeks swapping out the PCB (top right, based on RPi Pico2) and expanding the user workflows of the interface. Firmware on the Pico2 as well as the interfacing software are written in Rust. The actual interface is based on Slint @slint.dev. #Rust #RustEmbedded

Shot from top of an electronics box with no cover. Bottom right shows high voltage cabling. On the bottom right is a DC power supply. Top right of the box shows a custom electronics board holding a Raspberry Pi Pico 2. On top of the electronics box lays a ReTerminal that displays a GUI with overview information of the system, stating the sample temperature as well as pressures of the chamber and transfer system. The GUI also shows that all sample slots are currently empty. The whole box is integrated into an aluminum frame.

Clicking on that green link opens Thunderbird... I'm am kind of tempted to send a message, but what to write?

The top half of a table with title "Basic"
The first row shows "CPU" and the entry "CM4". The second row shows, underneath "CM4" the words: "Quad-core Cortex-A72@1.5GHz". "Cortex-A72@1.5GHz" is in green while the rest of the text is in white on a dark background.

Beautiful 22° halo around the Sun on this nice day near Geneva. Physics is beautiful! en.wikipedia.org/wiki/22%C2%B...

If you are looking for a new incubator, look for a model that has the control board **above** the chamber, especially if you work with salt water... Don't get me wrong, I love oxidized firmware #EmbeddedRust, not so much corroded components though.

Image of part of a printed circuit board for an incubator controller. The image focuses on the MCU and surrounding components, many of which show a blue-ish corrosion layer from saltwater damage.
