Drivers for the Texas Instruments Tiva C ARM 4F TM4C123GH6PM microcontroller.It is designed to be easy to use, similar to an arduino, however knowledge ofpointers and memory management is reccommended. This project is written in C++.

ARM GNU Toolchain is required to build this project.OpenOCD is required todownload main.elf to the board. Both are freely available to download and install.

You will probably have to add both openOCD and the ARM GNU Toolchain bin folder to your path

To build the example main, navigate to the project directory in a terminal anduse the commandmake.

Use the commandopenocd -f board/ek-tm4c123gxl.cfg -c "program main.elf"to download the code to the board. Hit the reset switch to reset the processor tosee the example code in action.

The commandarm-none-eabi-gdb main.elf can be used to access the debugger.

• Use the commandtarget extended-remote:3333 to connect to the board
• Use the commandmonitor reset halt to halt the processor (required to load code)
• Use the commandload to load new code onto the board
• Use the commandmonitor reset init to restart the processor
• The rest of the GDB commands are the same

This project is a work in progress. Class names, function names, enum names, etc..may change, with out notice, at any time.

• NVIC Interrupts
• PLL system clock for different clock speeds
• GPIO, GPIO interrupt on both edges
• 16/32-bit and 32/64-bit General Purpose Timer in oneshot and periodic mode
• PWM can be initilized for single and double ended complementary mode.
• ADC polling

Main contains a very simple example program of how to use the drivers.

• Test the ADC interrupt function
• Implement thevoid initializeDigitalComparator(void); functionality
• Add ADC documentation and update existing
• Refactor GPIO, PWM, GPT code to bring it inline with new framework

• µDMA
• GPIO
  • Poll raw interrupt status
  • interrupt on a single edge
• USB
• UART
• SPI
• I2C
• Systick
• MPU
• FPU
• SBC
• Analog Comparator
• Memory
  • EEPROM
  • Flash
• Hibernate
• Watchdog
• Examples folder

• Further test the ADC polling function
