Welcome to the Infineon Developer Community

Hello all,

I'm using the TLI49d-W2BW with a Raspberry Pi4,
I started with a code found on another thread in the forum, thanks to @Yashraj_P .

And it worked quite nicely during a long time.

But I'm having slight problems nowadays :
The sensor is working properly and I'm reading the values (Bx, By, Bz) of the sensor during an hour or more (values arriving each 20seconds),
And suddently the read values are not changing anymore, and I read Bx=-1, By=-1, Bz=-1
With or without a magnet around.

First is :

def initialize(self):
        # Enabling One-byte read, Clock Stretching enabled, /INT disabled, Master Controlled Mode
        self.pi.i2c_write_byte_data(self.h, 0x11, 0x15)
        # Temp enabled, Bz measure enabled, ADC trigger on reading after 0x05 register
        self.pi.i2c_write_byte_data(self.h, 0x10, 0x20)
        sleep(60e-6)
        self.update_data()

Then :

def update_data(self):
        (count, self.data) = self.pi.i2c_read_device(self.h, 6)

def get_x(self):
        self.bx = (self.data[0] << 4) | ((self.data[4] >> 4) & 0x0f)
        if self.bx > 2047:
            self.bx -= 4096
        # self.bx *= 0.098
        return self.bx

I tried few things and realised that when I'm launching my software, 
I'm in fact "initializing" the sensor to write the configuration to the register,
And later on when reading (clicking on a button or automatically during a sequence) the values, well I'm just reading them.

Once I have Bx=-1, By=-1, Bz=-1,
I quit the program and relaunch it then it works fine.
So the problem should be with the iniatilazion at that point ?
So now I have fixed the problem by initiazing the sensor every time before reading the values,
But I'm wondering if it really should be like this 🤔

Doeas anybody had a problem of the same kind ?
Did I miss something somewhere ?

Thanks a lot for the reading time,
A good day to all.

Hello, I need to know the correct part number associated to ordering code SP005591068.

BTS409L1E3062AA or BTS409L1E3062AB ?

Thanks.

Hi Infineon team,

      In some of our designs we use the SAK-C167CR-LM-HA+ microcontroller. Can we use SAF- C167CR-LM in place of it?

Are SAK-C167CR-LM-HA+ and SAF- C167CR-LM functionally equivalent? On page 59 of the datasheet, I can see that ambient temperature rating is different between SAK and SAF prefixes. Other than this are there any differences? What does the "HA+" stand for?

Thank you.

Regards,

我们这边使用BLE（CYW20829）作为SPI slave和MCU（TC387）作为SPI master，调试SPI通信时，遇到两个问题：

1.slave接收来自master的数据，rx中断不触发。

SPI初始化如下：

代码段参考：https://infineon.github.io/psoc6hal/html/group__group__hal__spi.html文档中的Snippet 4:Interrupts on SPI events

代码修改基于例程：https://github.com/Infineon/mtb-example-hal-spi-slave#readme

尝试：调试过程中发现，slave使用cyhal_spi_slave_write时，rx中断正常触发，看代码该函数调用了cyhal_spi_transfer_async

问题：只有slave一直调用cyhal_spi_transfer_async进行读/写操作，rx中断才正常触发？

解决方案：有没有配置可以让master写入数据时，slave就触发SPI rx中断？

2.slave使用函数cyhal_spi_slave_write向master发送数据时，没有等待master拉低片选并生成时钟信号，导致接收数据异常。

尝试：使用Cy_GPIO_Read读取CS引脚，直到该引脚被拉低。

问题：容易死循环，读取引脚数据一直为高电平。

解决方案1：能否帮忙调试出一个该方案可行的代码？

解决方案2：是否有其他slave write函数，是等待master拉低片选并生成时钟信号，才发送数据？

希望能给出上述问题的解决方案。

Hi,

I would like to test the bluetooth connection for cyw43439.

Currently the wifi sdio is working as expected as both STA and AP.

However, I could not get it recognized as a bluetooth device on my host.

I'm using and arm-32 based soc which is Ambarella s3lm board as my host. Currently, I've connected the UART pin to the host (CTS, RTS, Tx, Rx).

These are my output of the hci dev, no bluetooth device was listed.

# hcitool dev

Nothing on my device list as well.

I'm currently using the cywfmac backport driver for linux kernel 6.1 (murata hedorah branch)

Note that my host is using the BlueZ stack.

Any other configuration is required to enable this?

Please advise.

大家好，

     最近想用keil调试cyt2bt73cae这个芯片的程序，使用mtb导出的工程只有单核应用，然后device这里显示

，这种导出的工程直接是CM4的，编译过后能够达到使用CM0启动CM4的效果？如果不能，我应该怎么做？

 当我配置了cm0plus以后，cy_m0p_image[]这个数据的含义是什么，需要我手动调用吗？ 

当我使用导出的keil工程的GPIO中断时，无法进入终端服务函数，这和我没有CM0有关系吗？

希望有人能够帮到我，感谢~

There is said that this bright feet + logo a bit unlike is IR Mexico factory production, I can not judge, please gods look at, this is not authentic, thank you!

Hello

Does the "VDC_OUT" pin of CYPD3177 have a discharge function?

Because it's not specified in the datasheet.

Hi,

I would like to know of a sample code to write few bytes to an ISSI 128 MBits of nor flash memory and also basic communication pin andsetup for XMC71000D.

When i setup the memory with xmc7100D at P13 (SCB-SPI) the spi_initialization returns an error. how do i check the device id for this flash memory (ISSI;25LP128- jedec id : [9D6018])

best,

PA
