Video output is generated directly by the MCU using an external crystal oscillator and PLL for best quality. The CH32V003 runs at 48 MHz, providing about 50% more cycles per frame than the V002 due to one fewer flash wait state. The BASIC interpreter supports signed 16-bit arithmetic with 640 bytes of available memory, and keyboard input is handled via the ch32fun single-wire monitor. ## Full article daily.dev links to this article rather than hosting it.
