Generating rustdoc for github pages (Drone OS)

May 17, 2020

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.

STM32CubeF4 gcc makefile example for FreeRTOS

October 4, 2016

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.

Setting the date, time, and timezone on the Raise3D N2

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 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.
