Freescale ColdFire 32-bit Embedded Systems Book

About this manual

This book presents a step‑by‑step approach to building embedded systems using Freescale's 32‑bit ColdFire microcontrollers. It starts with an overview of the ColdFire family and detailed hardware minimum‑system designs for the MCF52233, MCF52235 and MCF52223 devices.

Subsequent chapters cover peripheral programming (UART, GPIO, LCD, AD, timers, QSPI, I2C, Flash, CAN) and provide complete source code examples, test cases, and a discussion of component‑level driver encapsulation. The text also includes practical troubleshooting Q&A for evaluation‑board usage. This manual is written in Chinese.

Frequently asked questions

Which port pins are LED1‑LED4 connected to on the MCF52233 evaluation board?

LED1, LED2, LED3 and LED4 are connected to TC port pins 0, 1, 2 and 3 respectively.

Why does the PC show ‘not connected’ when using the Ethernet interface?

A crossover Ethernet cable is required; a straight‑through cable will not establish a link.

What causes garbled characters in the PC serial‑debug window during UART communication?

The baud rate set in the PC terminal does not match the baud rate configured in the MCU.
