## Hardware

Platform TI TIVA: Texas Instruments TM4C12x MCUs offer the industrys most popular ARM Cortex-M4 core with scalable memory and package options, unparalleled connectivity peripherals, advanced application functions, industry-leading analog integration, and extensive software solutions.

Microcontroller | LPTM4C1230C3PM
Frequency | 80MHz
Flash | 256KB
RAM | 32KB
Vendor | TI

## Configuration

Please use `lptm4c1230c3pm` ID for board option in “platformio.ini” (Project Configuration File):

    [env:lptm4c1230c3pm]
    platform = titiva
    board = lptm4c1230c3pm

You can override default TI LaunchPad (Tiva C) w/ tm4c123 (80MHz) settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest lptm4c1230c3pm.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:lptm4c1230c3pm]
    platform = titiva
    board = lptm4c1230c3pm

    ; change microcontroller
    board_build.mcu = lptm4c1230c3pm

    ; change MCU frequency
    board_build.f_cpu = 80000000L

## Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

TI LaunchPad (Tiva C) w/ tm4c123 (80MHz) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
