PSoC™ 5, 3 & 1 Forum Discussions

I see that a year there is Mass Storage for PSoC 5:
KITPROG USB MASS STORAGE PROGRAMMER
But I do not see the sample code. Is that possible ?  )))

Hey everyone,

i figered out how to build a psoc 3.3 project from the commandline. But now i wonder how to inject macros from the commandline. eg. -DMAJOR_VERSION=2

Do you have any idea how to do this. It is quit important for setting up nightly builds and release builds with jenkins.

Best regards

Hi ,

    I have executed "USBFS_UART" code in Psoc creator 3.3 , program loaded successfully but we check into hyperterminal did not get any data.

Could you please give some suggestion how to check serial communication via hypertermnal.

Hi ,

      We are using CY8kit - 059 , in that we require serial emulation driver for USB . Could you please give some suggestion how to we get the Serial Emulation Driver for USB.

Hello,

can someone explain me if Is it possible that the GyroRate and AccelerometerRate are larger than the updateIMU-Rate (i do not mean the readSensorData-Rate, this is equal to the updateIMU-Rate) or does the algorithm / code than not work?

Thank you.

General Implementation of the "Madgwick Open Source IMU algorithm" (http://x-io.co.uk/open-source-imu-and-ahrs-algorithms/)

Pseudocode:

1. Init IMU-Hardware () 

- IMU Factory Reset

- Set IMU-ACC/GYRO "LOW-PASS-FILTER" 

- Set IMU-ACC/GYRO "Scale Range"

- Set IMU-ACC/GYRO "Sample Rate"

- Activate IMU-FIFO Buffer

- Set/calibate IMU-ACC/GYRO "OffSet "

2. While () //Limited to Madgwick() Sample Rate

- get IMU Raw Data

- calculate ACC-G-Values and GYRO-Rad/s-Values

- MadgwickAHRSupdateIMU

- calculate Angle

Note: 

-It is not strictly necessary for Accelerometer and Magnetometer measurements to be synchronised with Gyroscope measurements

-You can find on Github (https://github.com/xioTechnologies/Fusion) the new "xioTechnologies-AHRS-Lib" from 8.10.2016.

I am new to PSoC5 programming and need help to master its DMA data transfer.

I started a project that requires grabbing parallel port camera frame data at fast speed. The camera has 8-bit parallel port, VSync, HSync and Pixel Clock.  Data format is a 8-bit gray-scale. Resolution 320x240 (QVGA).

I started with single channel DMA arrangement. Basic structure is as following:

1. VSync isr resets the line counter and enables HSync interrupt,

2. HSync isr setup the destination line buffer start address in DMA channel, enables DMA and enables DMA done interrupt

3. following rising edge of pixel clock event triggers DMA read from the 8-bit port, write to the destination buffer and increment the destination address

4. DMA channel is set to length of 320

5. DMA done isr increment the line counter, if the line counter reaches the bottom (240), disable further HSync interrupt.

The above process works OK when camera pixel clock is set to 3MHz. The problem is that the above arrangement does not work for high pixel clock such as 4MHz. My project requires the pixel clock to be at least 6MHz.

Has anybody done the similar DMA? I would like to know if the 3MHz is indeed the DMA data transfer rate limit? If so, will a 8bit -16bit/32bit UDB buffer can help the overall data transfer rate? How such a UDB buffer can be created.

Thank you!
