    Trouble interfacing LPC2148 and Hitachi H48C accelerometer

    OK..So now what I am doing is shorting the MOSI and MISO wires and connecting them to the DIO of the accelerometer.Here is the code I am using #define SPIF (1<<7) #define LED_MSK 0x00FF0000 void Initialize() { /* Configure Pin Connect Block */ PINSEL0=0x5500; /* Set pclk to same as...

    Trouble interfacing LPC2148 and Hitachi H48C accelerometer

    This is what I understand 1. Select the accelerometer through CS. 2. Through a GPIO collect the output from the DIO Then, What signal do I give the clock? Is it decided my the sampling rate I desire(obviously less than equal to the acelerometers sampling rate) Also, How do I extract the data...

    Trouble interfacing LPC2148 and Hitachi H48C accelerometer

    Hi People The H48C has only one DIO pin. I cant figure out how to perform SPI comm. b/w LPC2148 and H48C since the LPC has MOSI and MISO. I have tried connecting the MISO and DIO , CS of both and coded up. But no help with that. I keep getting a mode fault with that. Any idea where I am going...
