This document is the user manual for the F2812 DEMO board, which introduces the resources and features of the F2812 DEMO board.
The F2812 DEMO board is a development platform for learning and familiarizing with the TMS320F2812 DSP. It includes the processor core, on‑chip Flash, SRAM and ROM, a 30 MHz crystal, voltage regulators, multiple communication interfaces (SPI, UART, CAN, McBSP), 56 GPIO pins, 12‑bit 16‑channel ADC, timers, watchdog, and extensive interrupt resources.
The manual supplies three example programs (cputimer, gpio, ad) with step‑by‑step instructions for loading GEL files, compiling projects in Code Composer, disabling the watchdog, and observing results with the watch window or an oscilloscope. It also details the procedure for on‑chip Flash programming using the SDConfig/SDFlash tools, project setup, and verification. This manual is written in Chinese.
