About Embedded Systems with TM4C123 @Valvano

A collection of example files and starter projects for embedded systems education, specifically for ARM Cortex-M microcontrollers including the TM4C123 (LM4F120) and TM4C1294. The projects accompany the three-volume textbook series by Jonathan W. Valvano: 'Embedded Systems: Introduction to ARM Cortex-M Microcontrollers', 'Real-Time Interfacing to ARM Cortex-M Microcontrollers', and 'Real-Time Operating Systems for ARM Cortex-M Microcontrollers'. Topics range from introductory examples and debugging to finite state machines, human interface devices, edge-triggered interrupts, serial interfaces (UART, I2C, SSI, CAN), data structures (FIFO, heap, linked list, interpolation), timers (SysTick, PWM, input capture), ADC/DAC, and advanced topics like WiFi, DMA, FFT, Flash EEPROM, and RTOS. The projects compile using Keil uVision4/5 and Texas Instruments Code Composer Studio (CCS). The files are free to use, edit, and distribute under the condition that copyright notices remain intact.

FAQ

What microcontrollers are supported?

The examples run on the LM4F120, TM4C123, or TM4C1294 microcontrollers.

Are the example files free to use?

Yes, they are copyrighted by Jonathan W. Valvano but you may use, edit, run, or distribute them as long as the copyright notices remain intact.

What compilers are supported?

Projects compile with Keil uVision4/5 and Texas Instruments Code Composer Studio (CCS).

How do I get started with the examples?

Download the appropriate zip file (e.g., ValvanoWareTM4C123.zip for Keil 4/CCS or ValvanoWaveTM4C123v*.zip for Keil 5) and unzip to get a directory structure with projects organized by microcontroller and topic.
