Linux on a CH32V006 based emulator: PCB
The schematic and PCB are done. I’ve gone for a compact SMD design with the CH32V006FxPx, 8 MiB of PSRAM, and 16 MiB of NOR flash. The CH32V006 does not support QSPI mode, but I’ve wired the memory to port C so I can efficiently implement it in software.
Linux on a CH32V006 based emulator: starting out
It’s been done before both on the RP2040 and CH32V003, but I’d like to develop a CH32V006 based emulator that can run RISC-V Linux. The goals are: Run RV32 Linux with a console, RAM, and SPI storage Make it as fast as possible.
LWZ 130 display protocol
The Stiebel Eltron LWZ 130 mechanical ventilator comes with a remote display that shows the current fan setting, temperature, and other settings, and also lets the user change the current fan setting or temporarily boost the fan.
Adding all the CH32V003s to Zephyr... so far
In follow up to my last post, here’s a video of 5 CH32V003 based boards running Zephyr and at least blinking a LED. From the left these are: Muselab nanoCH32V003 Maker Go QSZNEC Unnamed CR-CH32VXXX My own spin on CH32V003-GameConsole with a colour display wagiminator’s CH32V003-GameConsole Looking forward to kholia@’s PR landing.
Adding all the CH32V003s to Zephyr
kholia@ and I have been working on adding support for the low-cost CH32V003 to Zephyr, which got me wondering: how many readily available CH32V003 boards are there, and what would it be like support all of them to Zephyr?
Performance of a Minn Kota electric motor on an inflatable hull
As a summer project, I’m experimenting with adding an electric trolling motor on a 2.9 m inflatable. My medium term goal is to hook up a leftover Ardupilot and have the boat slowly take me around the lake in the most plesent way possible.
Faster SPI bitbang for Zephyr on the ch32v003
As part of porting Zephyr to the CH32V003, I’ve been working on my own spin of wagiminator@’s CH32V003 based mini game console. Once change was swapping the monochrome OLED dispaly for a 160x80 colour LCD with a ST7735R controller.
My own spin of the CH32V003 Mini Game Console
kholia@ and I are working on porting Zephyr to the CH32V003. While he’s sorting out license issues, I’ve been working on my own spin of wagiminator@’s CH32V003 based mini game console.
CH32V003 Mini Game Console build
I had fun building a few of wagiminator@’s CH32V003 based mini game console. This was my first time buying from LCSC, ad I was quite happy with the selection and turn around time.
Ampler eBike Bluetooth protocol
I have an Ampler Stout eBike which exposes metrics as Bluetooth attributes over GATT. I’d like to track the battery level and odomoter, so spent some time and decoded some of the attributes.
