random things I made and things I learnt making them
Designing the sequencer Previous Post So whats next? Well we need some way to set the steps on the sequencer. I want 16 steps per bar, each step can be illumintated by the user, with an ability to set the note (and the duration). The sequencer runs through the individual steps at a given tempo,…
Recap Previous post Previously I made the plan to design a sequencer for the original Novation BassStation. This would work by switching the connections on the ribbon cable that connected the keyboard to the motherboard. I mapped out the signal on the ribbon cable, now I needed to decide how to multiplex these signals electronically.…
Intro I just scored this original Novation BassStation synth on Ebay. It’s a hybrid synth that uses digital timing control courtesy of an MCU (Panasonic MN1883217) to control two analog oscilators. Legend tells that it has a richer sound than the rack mounted version. Well, i’m not qualified to verify such claims, but it is…
So you have the discovery kit and you’ve run the example image on the SD card. How do you build the image from scratch with Yocto and using a DTS file generated by STM32CubeIDE?
This is a completed version of the [What I wish I’d known about Yocto Project] page in the Yocto documentation. See https://docs.yoctoproject.org/what-i-wish-id-known.html
Some issues encountered when building the Yocto BSP for AM335x with the BeagleBone Black, and their solutions.
Using Dynamic Debug (debugfs) Check dynamic debug option is enabled in the kernel build grep CONFIG_DYNAMIC_DEBUG= /boot/config-uname -r If this is not enabled then you will need to set this option inmake menuconfigand rebuild the kernel Working with module names If you want to work with a single module use themodulequery and the module name…
The purpose of this project is to use a touch screen to control the server PSU. In turn the touchscreen will display information from the PSU including its status, voltage, current and other data via SMBUS protocol. They are useful for charging LIPO batteries (with some modification) and running brushless motors or any circuit that draws large amounts of current.
Using Google Sheets App Scripts to help write register macros
The purpose of this project is to design, build a programmable guitar FX pedal using a Cortex-M4F micro and I2S. This will provide a platform for development and experimentation of DSP algorithms and techniques. This is also an experiment to use C++ in embedded development.
