PB22 LED 闪烁教程

# Tianmengxing PB22 LED Blink Example

Minimal reference for blinking the onboard LED on the LCKFB Tianmengxing MSPM0G3507 board.

This example is based on the validated workflow summarized in ../../references/hardware_validation_notes.md. It is not a complete CCS import project. It is an agent-readable reference showing the .syscfg and C patterns that were verified on real hardware.

Clock Note#

This LED-only reference is the original 32 MHz baseline. Its main.c uses delay_cycles(32000000) for a rough one-second blink.

Later Tianmengxing work often uses 80 MHz CPUCLK. For 80 MHz examples, use delay_cycles(80000000) for the same rough one-second smoke test and see ../../references/hardware_validation_notes.md.

Files#

• example.syscfg: PB22 GPIO output configuration pattern
• src/main.c: DriverLib application code using generated macros
• manifest.json: machine-readable summary for example selection

Agent Notes#

• Configure the LED pin in .syscfg.
• On the Tianmengxing MSPM0G3507 board, the onboard LED used by the LCKFB LED tutorial is PB22.
• Do not manually edit generated ti_msp_dl_config.c or ti_msp_dl_config.h.
• After changing example.syscfg, run SysConfig or rebuild the real CCS project.
• Confirm the generated init function and macro names in the local generated header.

Expected Generated Names#

The example expects generated names similar to:

LED_PORT
LED_PIN_22_PIN
SYSCFG_DL_init()

Real projects may generate different names if $name or pin names are changed.
