This shows how to build the CH32V003 demo binaries without the horrifying MounRiver Studio.

• Product page: https://www.wch.cn/products/CH32V003.html
• or English: http://www.wch-ic.com/products/CH32V003.html
• It has, for the English datasheet http://www.wch-ic.com/downloads/file/359.html "CH32V003DS0.PDF"
• It also has the TRM http://www.wch-ic.com/downloads/CH32V003RM_PDF.html in English
• Sadly, the EVT is CN only. https://www.wch.cn/downloads/CH32V003EVT_ZIP.html - It contains schematics for the devboard, evaluation board reference (instructions) and the rest of the dev system, minus the MounRiver Studio (MRS).
• Software from WCH for WCH-Link: https://www.wch-ic.com/products/WCH-Link.html
• Get https://www.wch.cn/downloads/WCH-LinkUtility_ZIP.html
