PSoC™ 4 Forum Discussions

We produce products with CYBL10161，but all products have the same Bluetooth mac address。we must set the mac address by uart to send commond after programmed 。but it  is too complicated。i want to ask Is there a more convenient way to automatically generate the mac address at the time of programmed 。thanks for help。

Hi everyone,

I had a similar situation to the topic posted here: http://www.cypress.com/forum/psoc-4-architecture/reset-i2c

I'm trying to communicate with an I2C device but sometimes the device is hung up, (SDA low), and it doesn't work until I turn off the power, I was trying to use teh directives of the previous post, but the new component doesn't include them.

    while(I2C_1_sda_Read() == 0) // SDA hang low
    {
        I2C_1_SET_I2C_SCL_HSIOM_SEL(I2C_1_HSIOM_GPIO_SEL); //Switch to GPIO    
        I2C_1_scl_Write(0);
        CyDelay(1);
        I2C_1_scl_Write(1);
        CyDelay(1);
        I2C_1_SET_I2C_SCL_HSIOM_SEL(I2C_1_HSIOM_I2C_SEL); //Switch to Component
    }
    I2C_1_I2CMasterSendStop();

Is there another way to reset the I2C bus and get out from the infinite loop (Waiting ACK or NACK) in case the device got hung in the middle of the program?

Is CYBL10563 chip FCC certified?

Where can I find the FCC ID for details if Yes?

Thanks.

Hello,

I am new to this community and have no solid idea where to put this.

I find out that side effect of TCPWM_WritePeriod() function in Timer mode is same as in PWM mode but in datasheet mentioned only for PWM (screen shot attached).

I am using CY8C4247AZI-M485 and PSoC Creator 3.3

Hi,

I am working with the CY8CKIT-042-BLE PSoC 4/PRoC Pioneer Kit. I tried to run one of the example projects ( #29) on writing to SFlash and was not successful. The program seems to go into an infinite loop. In debug mode the program stops at CY_ISR(IntDefaultHandler). I haven't made any changes to the code and I'm not sure how to fix it. Any help will be appreciated.

Thanks

First,please forgive me for my poor English.

Which protocol is used when we write a program to the clip (like CYBL10563)? I guess I2C. Am I right? 

I'm a rookie here.  

I'm trying to send 3 bytes of data to a DAC, MAX5217, trough I2C. But I can't seem so send more than 2 bytes before the communication stops.

I'm doing:
            temp = I2CM_I2CMasterWriteBuf(I2C_SLAVE_ADDRESS, (uint8 *) sample,
                                        WR_BUFFER_SIZE , I2CM_I2C_MODE_COMPLETE_XFER);

With WR_BUFFER_SIZE set to 3,  but I only see the address + the first 2 bytes of my data with an oscilloscope. Setting the WR_BUFFER_SIZE to 1, sends 1 byte, anything above 1 sends 2 bytes.

Any ideas?
