RVPC2

Inspired by OLIMEX RVPC project, I decided to create a #higher-faster-stronger version.

Key differences:

Feature	V1	V2
MCU
Model	CH32V003F4P6	CH32X035G8R6
Pins	8	28
RAM	2k	20k
ROM	16k	64k
USB	X	V
Display
Color	mono (1-bit)	8 (3-bit)
Communication	X	V
Ports
PS2	V	X
USB	X	2.0 FS
Audio	X	3.5mm jack
Storage	X	Micro-SD
Power	5V, 5mm barrel	5V, USB-C PD

Build tools:

• IDE of your choice:
  • MounRiver
  • VSCode
• Compiler (in case it isn't bundled with ide): riscv-none-elf-gcc-xpack instructions page

Troubleshoot

In case MounRiver build fails with Bad CPU type in executable, try:

• right click on project name in project explorer (left top corner of the window)
• select Properties
• Build Settings->Target Processor->RISC-V Compiler: select WCH Toolchain(GCC12) or newer
