I want know why my code isn't work, I used to use in TM4C129 and edit the code to used in TM4C123GXL, but it doesn't work. #include <stdint.h> #include "driverlib/sysctl.h" #include "driverlib/qei.h" int pos; void setup() { Serial.begin(9600); // Setup QEI Module SysCtlPeripheralEnable(SYSCTL_PERIPH_QEI0); GPIOPinConfigure(0x00031806); //GPIO_PD6_PHA0 GPIOPinConfigure(0x00031C06); //GPIO_PD7_PHB0 GPIOPinTypeQEI(GPIO_PORTL_BASE, GPIO_PIN_1 | GPIO_PIN_2); // Configure and Enable QEI QEIConfigure(QEI0_BASE, (QEI_CONFIG_CAPTURE -
I am using TM4C123GXL and for some reason I am getting garbage values when I try to read the values from PB1 pin. I flashed this simple code to test the UART: void setup() { // initialize ports: Serial.begin(115200); //connected with USB } void loop() { Serial.print("E"); delay(200); } But instead of 'E' I see these garbage values: ;����������� I am reading using the same 115200 baud rate. What am I doing wrong? May be I do not flash the code correctly? I simply put the device into DEBUG mode and connect to my Ubuntu PC using the top micro USB port (red LE

i'm designing an embedded control system that i've prototyped with the TM4C123GXL Launchpad. i like the processor (TM4C123GH6PM) and need the speed. i'm experienced with code, hardware, board layout, etc. my question seems to be somewhat between a TI/hardware issue and an Energia software issue. for various reasons (including a desire to let eventual end-users write code for it) i want to use the Energia IDE with boards of my own design, that use only native USB, and not the secondary debug processor. the bootstrap process remains fairly opaque; i've read the datasheet and ROM app no

Hello, What is the status of Wire.h when using energia with the tiva-c board? Since there is the BoardManager in E18, the file layout has changed. Which leads to some confusion. eagle@daredevil:~$ find . -type f -name "Wire.h" ./.energia15/packages/energia/hardware/msp432/3.8.0/cores/msp432/ti/runtime/wiring/Wire.h ./.energia15/packages/energia/hardware/msp430/1.0.2/libraries/Wire/Wire.h ./.energia15/packages/energia/hardware/tivac/1.0.2/libraries/Wire/Wire.h ./.energia15/packages/energia/hardware/msp432r/5.6.0/cores/msp432r/ti/runtime/wiring/Wire.h ./bin/energia-1.6.10E18/hardware/en

Hello, i want to control relays with my keypad. I work with the Launchpad TM4C123 80MHz. i wrote a script but the relay isn´t working. The relay is alright and i don´t know the problem. Can anyone help me?

Hello guys, I am using the tm4c123 and I need to use the pins PD_4 and PD_5 in my custom board... but these pins have no definition in the Energia... I would like to use this pins as inputs (digitalRead function) I had the same problem with the PQ_4 on the TM4C129 Could I make some #define in the pins_energia.h to use this pins??? Regards

There is an edX course coming up in September from the University of Texas in Austin - this time with MSP432 or TM4C123 LaunchPad. The parts list also includes the CC2650 and Educational BoosterPack MK-II. The syllabus includes BLE and RTOS. It is taught by Jonathan Valvano and Ramesh Yerraballi who have offered a course using the TM4C123 on edX in the past. https://www.edx.org/course/real-time-bluetooth-networks-shape-world-utaustinx-ut-rtbn-12-01x http://edx-org-utaustinx.s3.amazonaws.com/UT601x/RTOS.html edit: forgot to mention that these courses are free if you just audit th -
Hello, I am having trouble using a SPI DS3234 RTC with Energia and TivaC series launchpad. I am using the ds3234 library at https://github.com/rodan/ds3234 which is originally written for arduino. I modified few settings in the initialization, tried few things, but have not had any luck. The module will not talk spi at all, and I get 1900.00.00 00:00:00 for date all the time. Here is the relevant code from the init section: void DS3234_init(const uint8_t pin, const uint8_t ctrl_reg) { pinMode(pin, OUTPUT); SPI.setModule(2); SPI.begin(); SPI.setClockDivider(SP

I was trying to get the Tiva Launchpad TM4C123 working with the Nokia 5110 using Energia. Eventually I came across this page: http://www.clarenceho.net/2015/08/tm4c123-with-dht11-sensor.html You can follow the series of questions and answers through which Clarence Ho helped me get the combination working. You can see that he used a library originally by Rei Vilo, modified to add a contrast command. You can see also that Clarence has now added the jump-wire connections which are needed to link the Launchpad and LCD, near the top of the page. I then investigated graphics, and added Graphics com -
This course by Jonathan Valvano and Ramesh Yerraballi at the University of Texas starts on January 20th. The lab uses the Texas Instruments TM4C123 ARM Cortex M4 LaunchPad. I haven't taken it but have heard good things about it. Additional information can be found here. EDIT: It's free if you don't want or need the certificate

Hello i have seen article about reading the supply voltage from MSP430 http://www.elevendroids.com/2013/06/code-recipe-reading-msp430-power-supply-voltage-level/ It can be usefull when running on batteries however i am not able to find anything suitable to use for TM4C123. The system DEFINES carries another names and the code can not be used. I have only used Energia for programming my LM4F120. If anyone have some experience in reading the internall VCC a and Voltage Reference to compute supply voltage level on TM4C123 I would be thankfull.

Hello, I've been looking trough the forums for an SD Card Library that can be used on TM4C123GH6PM micro controller. I came across one (http://embeddedcomputing.weebly.com/microsd-card-boosterpack.html) but the link redirects to the forum main page, so I can't really get my hands on it. Does someone has a low resource library for this? Thanks! Note: In case this is good to know, I'm looking to use the SD Card slot that comes with the ILI9341 2.2" LCD screen sold (mostly) on Ebay. So we're talking about an SPI-Interfaced SD Card.

Hi, I need to generate 4 pwm signals at 50 HZ, they need to run with out interruption. I know the TM4C123G6PM has 2 pwm blocks, but is it possible to access them through Energia? can I use Analog.write(); ? Someone please help. Thank you.

I found an adaptation of a cap-sense sketch that uses port manipulation to create a capacitive sensor for Arduino to a MSP430. My question is that when I was using the sketch and adjusting it to use a tm4C123 device, I got these errors: TouchSensor.ino: In function 'uint8_t readCapacitivePin(int)': TouchSensor.ino:58:24: error: 'P1OUT' was not declared in this scope TouchSensor.ino:59:23: error: 'P1DIR' was not declared in this scope TouchSensor.ino:61:23: error: 'P1IN' was not declared in this scope I looked into this and found out on this post: http://forum.43oh.com/topic/5166-need-adv
