Dave's Random Thoughts and Musings
I’ve been playing with DroneOS and created a crate with some
utility functions for the STM32F4xx series of processors. Unfortunately, the way that
Drone OS builds, you can’t call cargo doc directly. It needs to be invoked from
the drone program, which means that I couldn’t take advantage of Docs.rs.
This article is mostly just me documenting how I wired things up.
My GlowForge laser cutter finally arrived.
While working with a ConBee USB dongle for talking to Zigbee devices, I wanted to examime the serial stream being sent to/from the deConz program. This describes the steps I took to capture and examine the serial stream.
Following along from my earlier blog post STM32CubeF4 gcc makefile example, I modified the Makefile to work with one of the FreeRTOS examples included in the STM32CubeF4 (v1.13.0). This particular example flashes some LEDs on the STM32F469 Discovery board. The biggest wrinkle I ran into was having to add an _exit function. I grabbed a syscalls.c from elsewhere in the STM32CubeF4 tree and #if 0’d out some timezone functions which were failing to compile. You can find my repository with the Makefile, syscalls.c and instructions here.
I noticed that GHI Electronics makes a number of devices using the SM32F4 fmaily of processors, which also happens to be supported by MicroPython.
The filament spools that came with my Raise3D printer are 200mm in diameter, 70mm thick, and have a central hole about 55mm in diameter.
UPDATE: It turns out that later versions of the firmware now have the ability to set the timezone, date and time. I currently have version 0.6.5.3247 installed. To change the timezone, click on the little gear icon in the upper right corner, which will bring up “Settings”. Then chose the “Other” category and finally, “Date & Time”. You need to press on the > over on the right hand side.
I ordered a Raise3D N2 printer as part of a KickStarter campaign. All of the Canadian orders were container shipped to the good folks at filaments.ca and then shipped out to individuals.
I printed some clamps and knobs on my 3D printer:
