New "sensors" added to my #ch32v003 portable sensor platform - DS3231 and RV3032 RTCs. By getting rid of the floating point math of the LTR390, I've freed up enough space for a bunch more. Today I'll add some IMUs.
Progress on my SSD1306 OLED emulator on the #ch32v003 to a Sharp Memory LCD. Some clever use of SPI DMA and pixel rotation shortcuts allows it to keep up with a 400Khz I2C stream.
LCSC parts for my #ch32v003 USB Dev Board prototype just shipped today. I hopefully can show assembled prototypes in ~2 weeks. :)
Further work on the project. Now the layout of the power and charging circuit. The 4056h module makes the system simple.
Is it possible to recognize the supply voltage on #ch32v003. Mmm probably yes, use an ADC, though that might be too power consuming in and of itself 🤣

I am now in possession of 3 new boards with 3 different kinds of tiny #riscv processors needing to be added to @TinyGo #seeedstudio #espressif #esp32c3 #sipeed #bouffalo #bl702 #ch32v003

Got initial support for Sharp Memory LCDs written today (for the #CH32V003). Since it only has 2K of RAM, I made a "half-screen" 1K buffer that can be drawn to any set of 64 lines.
All code is shared here:

Not the prettiest soldering job out there, but my first #CH32V003 board actually works!

Not sure why the #CH32V003 #microcontroller keeps getting media attention while it continues to be a paper #release that can't be had at the promised <$0.10 price point.
Meanwhile, very little is being said (at least in Western press) about the #PY32F series, which is actually available in volume and some of which reach the same low <$0.10 price point: https://www.lcsc.com/search?q=py32f
#Available #parts beats paper releases in my book any day.

@strykeroz For the moment, I failed to program CH32V003 chip with Tindie devkit :(
I ordered the aliexpress kit which is slightly different and waiting for it to test.

I'm looking to create a whole series of super low BOM cost projects around the #CH32V003. I've got 2 in the works so far (Pocket CO2 meter and a personal wellness device). Anyone have other ideas to share?
