GPIO management library for Tiva-C Series TM4C123G. ... N108 is a full bare-metal real-time operating system for the TM4C123 chip, written from scratch.
The GPIO port pins of TM4C123G are multiplexed with different peripherals such as digital I/O, PWM, serial communication, etc. But each pin can be used for only one functionality at a time. GPIODEN register is used to enable GPIO pins as digital input-output pins.
Apr 14, 2013 · Last few days I spent a lot of time with the LM4F120 board just to get familiarized with the Stellarisware APIs. There are some documents available with the software which gives a good picture on the behavior of those APIs.
GPIO输出为3.3V，继电器正常吸合，但有时过了一段时间继电器会吸合失效，此时去量GPIO的输出电压，只有零点几伏，我可以肯定我程序没有对gpio做置0操 作。此时程序还在正常执行，说明tm4c123没有重启，设备没有复位。 我对GPIO配置为： low quality audio looper using SD card, implementing pushbuttons (TM4C123) - Looper.c. ... // Enable the GPIO port connected to the two onboard pushbuttons.
The TM4C123GH6PM microcontroller contains six ports and thus six of these physical GPIO blocks. Note that not all pins are implemented on every block. Some GPIO pins can function as I/O signals for the on-chip peripheral modules.

Hardware Block diagram of the TM4C123x microcontrollers, makes uses of the processor architecture core Cortex-M4, 32-bit. The board has 40 header pins, organized in 4 connectors : J1, J2, J3 and J4. The table below, show how J1 header pins are connected to the microcontroller pins and which GPIO functions can be selected. Memory Mapped Registers. Embedded systems can only get so far by executing normal Rust code and moving data around in RAM. If we want to get any information into or out of our system (be that blinking an LED, detecting a button press or communicating with an off-chip peripheral on some sort of bus) we're going to have to dip into the world of Peripherals and their 'memory mapped registers'.

GPIO Pin Pin Function USB Device PD4 USB0DM D– PD5 USB0DP D+ The TM4C123GH6PM target device is also capable of USB embedded host and on-the-go(OTG) functions. OTG functionality can be enabled by populating R25 and R29 with 0-Ωresistors. These resistors connect the USB ID and USB VBUS signals to PB0 and PB1. When these resistors are populated, Bits 31-8 from the return packet should be ignored. If GPIO_PIN_4 is high then the return value would be equal to GPIO_PIN_4 (GPIO_PIN_4 is actualy a value defined in the included files with the value 0x00000010). Example: If the PF4 input is 1 then, (value & GPIO_PIN_4) = GPIO_PIN_4. If the input is 0 then equal 0.
This looks like a decent minimal list for doing sysctl configuration (e.g. system clock and enabling peripherals) and GPIO: The TARGET_IS_TM4C123_RB1 #define we put in the project's symbols enables correct use of the MAP_ and ROM_ version of the various driverlib calls. Proof is in driverlib/rom.h:15.3.1 BitRateGeneration.....954 15.3.2 FIFOOperation.....955Now, about the concept TM4C123: GPIO >> DMA: GPIO as it is implemented has irregular timing responses, due to on-chip bus arbitration and delays across bus bridges. Sampling rate cannot be specified - usually to realize sampling, you use a timer, but this will introduce delays due to interrupts.
Protection is provided for the GPIO pins that can be used as the four JTAG/SWD pins If you check the signal tables on page 1329, you will see that PF0 ,where one of your switches is connected to, is one of them.
