PSoC 4 MCU

New Contributor II

This is the code that I have for both the module and the kit. I'm not sure what is going wrong, but my buffers are not being filled on the module side... now, I was able to get the data across but that has since ceased. Any help or suggestion is appreciated!

PSoC 4000s functions:

#define BUFFER_SIZE     0x02

void fillBuffer(int data1, int data2){

     for(uint8 i =  0; i < BUFFER_SIZE; ++i){

        wrData1 = (data1 & 0b1111111100000000) >> 8;

        wrData2 = (data2 & 0b1111111100000000) >> 8;

        if(i < 1){

           data1 = data1 << 8;

           data2 = data2 << 8;

        }

       

    }

}

void write2BLE(uint8 addr, uint8 buffer[]){

    /* clear any previous states */

i2c_I2CMasterClearStatus();

i2c_I2CMasterWriteBuf(addr, (uint8 *) buffer, BUFFER_SIZE, i2c_I2C_MODE_COMPLETE_XFER);

  while(0u == (i2c_I2CMasterStatus() & i2c_I2C_MSTAT_WR_CMPLT)) continue;

}

EZBLE Module function:

void i2cBufferSetup(uint8 dataBuffer1[BUFFER_SIZE], uint8 dataBuffer2[BUFFER_SIZE]){

        i2c_EzI2CSetBuffer1(BUFFER_SIZE, BUFFER_SIZE, dataBuffer1);

        i2c_EzI2CSetBuffer2(BUFFER_SIZE, BUFFER_SIZE, dataBuffer2);

}

If you're using the EZ module from the same kit, you can refer to the code example CE 210709 which has a similar implementation. In case you find any difficulty, do come back.

My problem is that the data I am sending from the kit is not being received by the ble module. Here are my project files.

Thanks again,

Julian

Are you using the EZBLE module available in the 4000S Pioneer kit or a separate EZ BLE module?

I am using the module onboard the kit.

Thank you,
