  1. Hi all! We are using Tiva C series MCUs (TM4C1294XL and TM4C123GXL) for a project in IICDC 2019 but we are facing problems while implementing Controller Area Network protocol (CAN Protocol) using them. I've attached the basic code for sending messages via CAN protocol form one MCU to other but the problem is, it is not doing so as a message sent from one MCU is received by itself and not by other MCU in the network. We've tried using the filters as well but no progress. Any help would be really appreciated. P.S. - Do we require an extra CAN transceiver boosterpack for these modules
  2. I am working on TM4C1294XL board and through Energia platform. I am trying to get the outputs from BMG250 shuttle board. I am pasting the code below but I believe the code has no fault. I have doubts about the connections to the shuttle board. I am getting -1 (when dividing outputs by 256) in all the three axis. I am sharing the schematic pdf that has information about the shuttle board connections. I have connected as given in the file but I have the following doubts: 1. How can set the pmu_status to normal gyroscope as it is mentioned in the datasheet as only readable? And when I read t
  3. I am working on TM4C1294XL board and through Energia platform. I am trying to interface HMC5883L of GY-80 with TM4C1294XL board. I am getting static outputs irrespective of whether I initialize all the essential registers or initialize none, the static outputs do not change in both cases. I am pasting the code below, I suspect that something should be wrong with the code as there nothing much to do in connection (only four wires needed). #include "Wire.h" #define cra 0x00 #define crb 0x01 #define modeReg 0x02 #define data_X_MSB 0x03 #define data_X_LSB 0x04 #define data_Y_MSB 0x07 #defin
  4. I am trying to interface GY-80 (only adxl345) to TM4C1294XL board using Energia. But outputs comes out to be 0. And also there comes this error "Failed to load dynamic library: 'ftd2xx.dll' " while uploading but the code gets uploaded successfully. I am pasting the code below, can somebody tell me where i am doing it wrong? #include "Wire.h" #define Power_Register 0x2D #define BW_rate 0x2C #define Int_enable 0x2E #define dataFormat 0x31 #define X_Axis_Register_DATAX0 0x32 #define X_Axis_Register_DATAX1 0x33 #define Y_Axis_Register_DATAY0 0x34 #define Y_Axis_Register_DATAY1 0x35 #define Z
  5. Hey all! Finicky issue, and I've been up for way too many hours so I'm breaking from usual habit and posting after only doing minimal digging. Hopefully it's a simple solution. Fingers crossed. Board: TM4C1294NCPDT IDE: CCSv6.1 OS: Ubuntu 16.04 Compiler: GNU v4.9.3 (Linaro) So here's what's up: I'm versed using timers and setting up my vector table properly, or so I thought. Code Composer Studio isn't finding my interrupt handler... It's confuzzling me to say the least... Here's what I'm doing: In startup_gcc.c //......Skipping top of file for readability, all is stoc
  6. 0down votefavorite Hi, I am trying to implement Modbus TCP on TIVA 1294 using the following code. I am using a modbus slave simulator on a pc to check the following code. However, the code doesn't seem to be working. I have downloaded the code & the libraries fromhttp://myarduinoprojects.com/modbus.html. Please suggest me corrections if necessary. Also is there another working example available for modbus tcp/ip for ethernet on TIVA energia? Please guide. #include <SPI.h> #include <Ethernet.h> #include "MgsModbus.h" MgsModbus Mb; int inByte = 0; // incoming seri
  7. Hi, I want to implement a code for Modbus RTU over TCP/IP usng TM4C1294NCPDT launchpad. Does anyone know a library which can be used to implement it. Also is it possible to obtain data from a PLC using modbus TCP/IP and send it to a Server on cloud using the same ethernet port? Please help. Thanks.
  8. I have experience with the traditional C programming in Code Composer and have implemented a timer interrupt routine in CCS for TIVA TM4C1294, now I want to create a timer ISR in Energia, how do I proceed ?
