Hi. I seem to get the following error whenever I try using "GPIOPinConfigure()" as shown below: However I do NOT get the error whenever the function "GPIOPinConfigure()" is NOT used: In essence, I want to be able to make a SSI connection with two TM4C123GH6PM launchpads in order to send temperature information (from one end) and print it onto a Kentec LCD screen (at the other end). The complete code of the sender is posted in the following: #include <LiquidCrystal.h> #include <DHT.h> #include <st -
RF Wireless LCD Temp Monitor Using TM4C123 & MSP432
lalo630 posted a topic in Energia - TivaC/CC3XXX
Hello, I want to make a wireless thermometer using two microcontrollers. How do I write the code in Energia to transmit and receive a variable using a 433 Mhz RF module? Transmitter Setup: I have a TM4C123G connected to a RF transmitter using TX(3) pin 34 on the MCU. The TM4C123G is also connected to a LM34DZ Temp sensor. I need help to modify this working code to send the temperature variable using tx(3) pin 34 /*TM4C123G*/ //initializes/defines the output pin of the LM34 temperature sensor int outputpin= A11; // (pin # 2), use A11 analog input //--------------- -
Is there a way to use the SoftwareSerial library on the Stellaris Launchpad TM4C123GXL board? I am trying to connect a Sparkfun serial enabled LCD screen to the board but the SoftwareSerial library is only compatible with 20, 16, and 8 MHz processors, and the TM4C123GXL is an 80 MHz chip. How can I use this LCD screen with the Stellaris Launchpad over a UART connection? Do I need to use SoftwareSerial or can I do without it? I am programming in Energia 0101E0017 on Windows 7 64 bit. Any help is greatly appreciated, thanks! -
Hi, I wonder if it is possible to cause a interrupt when receiving serial data. This would have the big advantage to be able to wake up from sleep mode if new serial data is available. By now, serial data is written in the rx buffer even in sleep mode, but afaik it's not possible to notice that in Energia. I found lots of code for CCS for exactly this application, but i'm not able to port it for Energia. Does anybody already has some example code or may help me to make the CCS code working in Energia? Thanks!

Hi I'm new with energia and I'm trying to use the Hardware serial communication with a Lauchpad Rev. 1.4 so I connect the RX end TX jumpers in cross but it doesn't work...Can anyone help me? this is the simple code I use: void setup() { Serial.begin(9600); } void loop() { Serial.println("Hello !!!"); delay(500); } I try to use also the software serial communication for but it doesn't work
