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
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
i would like to interface a multiplexed 4-digit-7-segment common anode display with msp430 g2 launchpad and display 4 numbers simultaneously.here the 4 digits are controlled by 4 BC547 transistors. here the segments a,b,c,d,e,f,g,dp of the display are connected to port1 pins respectively and the transistors bases are connected to port2 pins. i tried with single 7-segment display and it is working .when i extended to 4-digits i could not get the display. could you please give me the code to display 4 numbers simultaneously. thank you...
