PSoC™ 6 Forum Discussions

I'd like to know that Specific Absorption Rate (SAR) of  CYBLE-416045-02 since FCC Part 15 Subpart C as potable device.

How can I find the datasheet of SAR of CYBLE-416045-02?

Hi,

This question is related the question below

PSoC 6 Vbackup current

The customer is seriously trying to estimate the backup coin battery life.

And they asked us if the battery can be drained by P0 during VDDD is present.

At first from the description of 15.3 Power Supply, I thought that only when VDDD voltage goes lower than VBACKUP,  it can happen.

================

VDDBAK_CTL = 0 (Default mode): Selects VDDD when the brownout detector in the system resources is enabled and no brownout situation is detected (see the

Power Supply and Monitoring chapter on page 129 for more details). Otherwise, it selects the highest supply among VDDD and VBACKUP.

================

But seeing the diagram, I noticed the path (red line) exists, which is not controlled by the Backup Power Switch.

So I lost my confidence. It looks like if some port sync a lot of current, Vbackup can be used to help VDDD.

Question:

Is there a case when VDDD presents, but VBACKUP is also consumed?

Especially when VDDD is not lower than VBACKUP (but current may not be sufficient.)

I work for a non profit organization for "Human Trafficking". I was looking at the PSoc 6 version. Or Psoc 1. I am looking for two way audio and digital communication using WiFi. I do not know the range of the WiFi on the Psoc6 version but I can always add a WiFi repeater. I will also need one port to send predefined messages. There will be an operator at the reception desk.

What would be the best choice for two way audio, at least one IO port.

Note: I have been tasked to set up the file server server, Security cameras and intrusion alarms. My plate is full. I need a SDK to get on line ASAP. Please send me an email for more details. I am handicapped and I will have at least two technicians to do the manual work. I have Orthostatic Hypo tension. I can't control my blood pressure.I will need at least 100 of these SDK boards. I do not have time to develop the board. I can do a Psoc 1 board. But I don't know what to use for audio and WiFi.

We're working on a project that requires 5 or 6 hardware counters. Using Count7 works well, but we only need 3 bits of those counters and we're running out of UDBs for other tasks.

So: is it possible to implement 2 3-bit counters using just one UDB? That would be quite a relief. We'd need (roughly) the following API:

- initialize and enable

- set period

- read and write current counter value

The component would have two clock inputs and two cnt[2:0] outputs. A tc output is not necessary.

Hi,

I'm digging deeper into the PSoC 6 devices. As far as I can see PSoC 63 and upwards are BLE 5.0 devices. Will they also support BLE 5.1? Is this only related to the BLE software stack or would it need a new device?

Regards

What is the Maximum DMA Speed for a PSoC 6? I run Clk_Peri at 100MHz and get a Frequency of 9.14 MHz for 32Bit Memmory to Memmory Transfers. I only Trigger once for 256 Words in a 1D Transfer. Are higher speeds Possible? The M4 is not Started.

I need a parallel Capture with at least 16 MHz.

I'm trying to use CMSIS-DSP (CMSIS DSP Software Library ) in PSoC Creator:

PSoC Creator 4.3

Peripheral Driver Library 3.1.2

I got CMSIS from CMSIS_5/CMSIS/DSP at develop · ARM-software/CMSIS_5 · GitHub , and tried to adapt the instructions for "Building only the CMSIS-DSP library" in CMSIS_5/README.md at develop · ARM-software/CMSIS_5 · GitHub .

I had to go into CMSIS_5/CMSIS/DSP/configCore.cmake and SET(HARDFP OFF) to get something compatible with PSoC Creator.

I put:

SET(CMAKE_C_FLAGS "-mcpu=cortex-m4 -mfloat-abi=softfp -mfpu=fpv4-sp-d16 -mthumb -ffunction-sections -ffat-lto-objects -Os")

in CMakeLists.txt.

Then, I ran this command in my build directory:

cmake-3.17.3-Linux-x86_64/bin/cmake -DROOT="/mnt/c/Users/carlk/CMSIS_5" \

  -DCMAKE_PREFIX_PATH="/mnt/c/Program Files (x86)/Cypress/PSoC Creator/4.3/PSoC Creator/import/gnu/arm/9.3.1/bin" \

  -DCMAKE_TOOLCHAIN_FILE="/mnt/c/Users/carlk/CMSIS_5/CMSIS/DSP/gcc.cmake" \

  -DARM_CPU="cortex-m4" \

  -G "Unix Makefiles" ..

and then ran

make VERBOSE=1

Resulting in these libraries:

./bin_dsp/BasicMathFunctions/libCMSISDSPBasicMath.a

./bin_dsp/BayesFunctions/libCMSISDSPBayes.a

./bin_dsp/CommonTables/libCMSISDSPCommon.a

./bin_dsp/ComplexMathFunctions/libCMSISDSPComplexMath.a

./bin_dsp/SupportFunctions/libCMSISDSPSupport.a

./bin_dsp/SVMFunctions/libCMSISDSPSVM.a

./bin_dsp/TransformFunctions/libCMSISDSPTransform.a

To start with, I am trying to adapt this example: Practical FFT on microcontrollers using CMSIS DSP – M0AGX  There is really not much to it:

void fft_test(void){
static arm_rfft_instance_q15 fft_instance;
static q15_t output[FFT_SIZE*2]; //has to be twice FFT size
arm_status status;
status = arm_rfft_init_q15(&fft_instance, 256/*bin count*/, 0/*forward FFT*/, 1/*output bit order is normal*/);
printf("FFT init %d\n", status);
arm_rfft_q15(&fft_instance, (q15_t*)_mnt_c_Users_carlk__Documents_Audacity_679hz_raw, output);
arm_abs_q15(output, output, FFT_SIZE);
for (uint32_t j = 0; j < FFT_SIZE; j++){
printf("%d ", output);
}
printf("\n");
}

What am I doing wrong?

Hi,

The PDL's documentation for Cy_Crypto_Aes_Init() states that "Call to initialize this encryption technique before using any associated functions. You must initialize this technique again after using any other encryption technique."

For me, that means that if I only use AES encryption, I only have to call this once at the beginning. However, I'm also toggling between computing CRCs and encrypting data with AES. CRC is not an encryption technique, so must I still call Cy_Crypto_Aes_Init() after using Cy_Crypto_Crc_Run()?

Thank you,

Fred
