  1. Hello, I am trying to port Sparkfun's library to get the apds-9960 Gesture Sensor working on my Tiva C 1294 board. I set up the library like you normally would with ardunio while changing the interrupt pin and uploaded the code to my board with no issues. The only problem is when I go to serial monitor I get nothing printed to screen. Are there any other steps I need to take in order to convert this code to work on my Tiva board? I also tried moving to code composer studio but I cant find many clean tutorials on how to use it. I also have a MSP432 that I might try to get his working on if
  2. Hi, i need to use systick and serial comunication, but i cant serial communication works. I am using TM4C1294XL board. I've tested diferents values for Serial.setTimeout(10) (2, 10,50, 100) but no results Any idea? Thanks #include <stdint.h> #include "Energia.h" #include "driverlib/systick.h" #include "driverlib/systick.c" #include "driverlib/sysctl.h" #include "driverlib/adc.h" #include "wiring_private.h" #define pin 2 //PE4 #define SamplingFreq 60000 //Sampling frequency in HZ #define TickerPeriod (120000000/SamplingFreq) String inData = ""
  3. 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
  4. 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
  5. 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
  6. Hello, I wrote a very simple PWM Code for my Brushless DC Motor (incl. ESC) and it works very good (I don't use any Potentiometers.): int motorPin = PF_1; void setup() { pinMode(motorPin, OUTPUT); } void loop() { analogWrite(motorPin, HIGH); delayMicroseconds(1000); analogWrite(motorPin, LOW); delayMicroseconds(19000); } I need 50Hz (1/50=20us). The Motor breaks when the first delay is "1000us" and the second is "19000us". The Motor arrives highspeed when the first delay is "2000us" and the second is "18000us" So my dutycycle should be between 5 - 10% What
  7. Hello, I am a long time Arduino user, and I was tempted by the $20 price on the newest "Connected" launchpad TM4C1294XL. Seemed mighty powerful for the price! So I am basicly a noob only when it comes to this platform, and I've been going thru the tutorials and 'getting started' videos and I'm still stuck. First of all, I am trying to get started and the "Blink" example does not work on this board. Apparently because whatever I/O pin that Energia maps as "RED_LED" is not the same as any of the I/O pins that drive the 4 LEDS on my TM4C1294XL board. According to the docs for my board,
  8. I have a problem with Tiva C Series EK-TM4C1294XL LanchPad. .Totally is blocked: ( Only the green LED1 illuminates with low-intensity! I wanted to incorporate a greater value for WDT timer but I made a mistake and enter lower. I wanted to reset every 10 seconds. And I enter WatchdogReloadSet (WATCHDOG0_BASE, SysCtlClockGet () / 10000). Instead of WatchdogReloadSet (WATCHDOG0_BASE, SysCtlClockGet () * 10000). Now microcontroller is continuously in reset and can not be programmed with ICDI. Following message appears: Unable to find any ICDI devices. How to solve this problem? Co
