Hello,
I would like to use the i2c bus to talk to a sensor. With arm cortex m3 MCU I am use of setting up i2c like below:
void configure_I2C2(void)
{
I2C_InitTypeDef I2C_InitStructure;
//I2C2 peripheral configuration.
I2C_InitStructure.I2C_Mode = I2C_Mode_I2C; //I2C communications instead of SM bus.
I2C_InitStructure.I2C_DutyCycle = I2C_DutyCycle_2; //I2C fast mode Tlow/Thigh = 2.
I2C_InitStructure.I2C_OwnAddress1 = 0x01; //Can be anything when using just one slave device.
I2C_InitStructure.I2C_Ack = I2C_Ack_Enable; //Acknowledgement is enabled.
I2C_InitStructure.I2C_AcknowledgedAddress =
I2C_AcknowledgedAddress_7bit; //Specifies a 7-bit acknowledge address versus 10-bit.
I2C_InitStructure.I2C_ClockSpeed = 100000; //Clock speed is 400KHz
/* Enable the I2C2 peripheral */
I2C_Cmd(I2C2, ENABLE);
I2C_Init(I2C2, &I2C_InitStructure);
}
With the broadcom unit i do not see any header files with such data or any example?
Is there any good example out there that i can use as a guide?
or anyone who can help?
Regards,
Luke.
Hello i am using the BCM92073X_LE_KIT. In the sdk supplied with this module is a schematic. In the picture attached you will see a green box, within this box you will see numbering beside each pin out in red. can someone tell me what this is?

Show LessHi, Madam/Sir,
Broadcom announced WICED supported to full Apple HomeKit. I have few questions about it.
Q1: Which WICED SMART SoC P/N support Apple HomeKit? BCM20732/S, BCM20736/S, BCM20737/S
Q2: Does it need external memory to implement HomeKit stack on BCM2073X?
Q3: Does BCM2073X handle the authorization procedure w/ Apple CP (Authorization Co-processor)?
Cheers,

Show LessHi,
I'm experiencing some disconnection issues under IOS. Never had problems under Android and win 8.1.
It happens that with system in idle state or not, BLE disconnects randomly.
Problem is more frequent on certain units.
Can you help me?
Thank you,
Franco
