Need help getting initialized with MSP430F5529 to lsm303agr using STMems_Standard_C_Divers

[JBonn]

 P4SEL |= 0x06;              // Assign I2C pins P4.1, P4.2 to USCI_B1

 UCB1CTL1 |= UCSWRST;           // Enable SW reset

 UCB1CTL0 = UCMST + UCMODE_3 + UCSYNC;   // I2C Master, synchronous mode

 UCB1CTL1 = UCSSEL_2 + UCSWRST;      // Use SMCLK

 UCB1BR0 = 12;               // fSCL = SMCLK/12 = ~100kHz

 UCB1BR1 = 0;

 UCB1CTL1 &= ~UCSWRST;           // Clear SW reset, resume operation

ret = lsm303agr_read_reg(ctx, LSM303AGR_WHO_AM_I_A, &ACC_Data_Raw[0], 1);

How do I define ctx?

Hi jerry, if that code doesn't work (ctx should be the I2C slave ADDR that for lsm303agr is 0011001b on 7-bit), you could check with the code from here lsm303agr.c. In general, you can point our you findings directly on the STMems_Standard_C_drivers github forum. Regards
