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_Axis_Register_DATAZ0 0x36 #define Z_Axis_Register_DATAZ1 0x37 #define fifoCntrl 0x38 int ADXAddress = 0x53; int X0,X1,X_out; int Y0,Y1,Y_out; int Z1,Z0,Z_out; float Xa,Ya,Za; void setup() { Wire.setModule(0); Wire.begin(ADXAddress); Serial.begin(115200); delay(100); Wire.beginTransmission(ADXAddress); Wire.write(Power_Register); Wire.write(8); Wire.write(BW_rate); Wire.write(10); Wire.write(dataFormat); Wire.write(11); Wire.write(fifoCntrl); Wire.write(0); Wire.endTransmission(); } void loop() { Wire.beginTransmission(ADXAddress); Wire.write(X_Axis_Register_DATAX0); Wire.write(X_Axis_Register_DATAX1); Wire.endTransmission(); Wire.requestFrom(ADXAddress,2); if(Wire.available()<=2) { X0 = Wire.read(); X1 = Wire.read(); X1=X1<<8; X_out =X0+X1; } Wire.beginTransmission(ADXAddress); Wire.write(Y_Axis_Register_DATAY0); Wire.write(Y_Axis_Register_DATAY1); Wire.endTransmission(); Wire.requestFrom(ADXAddress,2); if(Wire.available()<=2) { Y0 = Wire.read(); Y1 = Wire.read(); Y1=Y1<<8; Y_out =Y0+Y1; } Wire.beginTransmission(ADXAddress); Wire.write(Z_Axis_Register_DATAZ0); Wire.write(Z_Axis_Register_DATAZ1); Wire.endTransmission(); Wire.requestFrom(ADXAddress,2); if(Wire.available()<=2) { Z0 = Wire.read(); Z1 = Wire.read(); Z1=Z1<<8; Z_out =Z0+Z1; } Serial.print("Xa= "); Serial.print(Xa);Serial.print("\t"); Serial.print("Ya= "); Serial.print(Ya);Serial.print("\t"); Serial.print("Za= "); Serial.println(Za); delay(1000); Serial.println(); }
