PSoC™ 6 Forum Discussions

Hello -

Another PSoC 6 crypto library question.

This page: PSoC 6 Peripheral Driver Library: Client Functions describes a pair of ECDSA functions (Cy_Crypto_ECDSA_SignHash/Cy_Crypto_ECDSA_VerifyHash), but the PDL documentation (3.1.2) for my PSoC creator install makes no mention of it.

Is this similar to the RSA 4096 bit support (coming to PDL in the future, and only on newer chips)?

I try to communicate with an RFID-Click board with SPI.

For the first touch i decide to use the low level API from Cypress.

Now i´m stuck while i try to read the ID of the Chip.

I hock up a Oscillocop on the SPI bus.

When I watch the Transfer all seems to be okay.

When I plot the Values readed from the rxBuffer I don´t get the expected results.

txBuffer[20]=0;

rxBuffer[20]=0;

void ClearSPIBuffer(){

}

for Write i used:

void SPIWrite(length){

     Cy_SCB_SPI_WriteArrayBlocking(SPI_1_HW,txBuffer,length);

     while(!Cy_SCB_SPI_IsTxComplete(SPI_1_HW)){

          vTaskDelay(0);

     }

}

read i try with:

txBuffer[0]=ID_CMD;

SPIWrite(1);

ClearSPIBuffer();

txBuffer[0]=read_CMD;/*reading cmd specify by the RFID Chip*/

txBuffer[1]=0xFF;/*Send Dummy Byte for reading*/

txBuffer[2]=0xFF;

txBuffer[3]=0xFF;

...

txBuffer[16]=0xFF;

txBuffer[17]=0xFF;

SPIWrite(18);

while(Cy_SCB_SPI_GetNumInRxFifo(SPI_1_HW)!=18);

Cy_SCB_SPI_ReadArray(SPI_1_HW,rxBuffer,18);

for(uint8_t i=0;i<18;i++){

     printf("recived %u: %u\r\n",i,rxBuffer[0]);

     vTaskDeleay(0);

}

On the Oscilliskop i can See the Correct ID but on the Serial Consol i Just get 0x06 what is the resulst from Polling and Echo command what I´m using bevor.

I try to get the correct Code from the SPI_MAST_LOW_LEVEL example.

What do i making wrong to read from an SPI Device?

Is the rxBuffer Updatet by write with Cy_SCB_SPI_WriteArrayBlocking(SPI_1_HW,txBuffer,length) ?

Hi

I am looking for a footprint/dimensional drawing for the CY8CPROTO-063-BLE  board. I am looking through the documents about the kit on the website, have a general pdf (but others won't download). I haven't seen anything like a plan drawing or 3D yet. Can anyone point me to one?

Many thanks for any advice.

Hi,

I got a new CY8CKIT-062-WiFi-BT. When I try to program it using the PSOC creator. It is not being listed under the targets.

What would have been the issue. I am using PSOC Creator 4.2. First thing is I wanted to rule out the issues present on board if any. Kindly help me with this.

Dear Sir/Madam,

We have requiement for configurating the PSoC6 working as QSPI slave with 27MHz input clock from QSPI master.

Checked Datasheet and TRM covered the configuration of SMIF as Dual/Single QSPI Master only without stating any Slave clock input parameters like while SCB standard SPI slave.

Can anybody confirm that QSPI slave possibility on PSoC6?

Thanks and Regards,

Kevin

Hi Sir,

I have some question want to ask next,

  (1)PSoC6 UDB part concrete can do?

（2）what is the difference between it and CPLD or relationship, as well as the specific usage, as well as the specific how many resources, whether can realize a little more complicated point of application, to do some algorithm, its peaceful LUT lookup table of commonly used exactly is what relationship, if we can develop a serial port?

（3）Whether UDB can do sequential logic？

Thanks

Paddy

我们使用PSOC6外挂nandflash，想通过USB接口连接PC，枚举成USB MAX storage，将设备拷出，

能提供相关的例程或技术文档来实现吗？

Hi,

In the below code I have tried to trigger an interrupt when the GPIO pin goes to low. I have understood that all the interrupt sources that are available can be found in  the type def IRQn_Type.

1. But where do I get the Interrupt Priority ( IntrPriority ). What should be the value of it?

2. I am assuming that this is the flow for programming a interrupt. Please correct me if I am wrong.

• Initialize interrupt using Cy_SysInt_Int()
• Enable the interrupt using NVIC_EnableIRQ()
• Define the Interrupt Sub Routine.

3. Is there any documentation describing how to program and handle different types of interrupts? Example: When a FIFO is full, When ADC has captures a data, etc. It can be generic as well.

4. When I am debugging using the PSOC Creator. If I try to add watch for a variable. The value is not being displayed. It is being displayed as optimized value. Where should I modify the optimization settings to see the value of the variable added to the watch..
