Hi Team,

i am using XMC440 platform2go evaluation board and wanted to do SPI communication in loopback mode.

for that i am referring SPI_SLAVE example present in DAVE and configuring SPI pins present on the arduino board.

I am selecting only SPI_MASTER with direct mode and using SPI_MASTER_TRANSMIT function to check whether clock is generating.

Issue is i am not able to see any clock and chip select signal in CRO.

please suggest what are the steps i need to follow or anything i am  missing.

Thanks,

Gargi

Hi

I am trying to implement the XMC4800 on a PCB but can only access the V1.0 design (https://www.infineon.com/cms/en/product/evaluation-boards/kit_xmc48_relax_ecat_v1/?tab=~%27pcb_data#!designsupport) 

The supplied Eagle files were last updated in 2015 and do not contain the necessary components to use the ADIN1200 PHY and new magnetics.

 

Could you please supply a zip file with the relevant Eagle files for the V2.1 design? 

 

Kind regards

Corben Taylor

Hi 

Myself : Nihal khan

i want to know the use of sample_time_std_conv (/**< Sample time for channels directly connected to VADC
<BR>Range: [0x0 to 0x1F] */) in adc configuration

Hello, I am looking for an Application Note and accompanying Example Code for the HRPWM in XMC4000. I am using DAVE Can you be so kind and provide me with it. I saw a post and downloaded the HRPWM.zip file from the XMC Forum. Unzipped in Dave and had error message main.c not found. Thank you and best regards, Jousif Show Less

Hi everyone,

Using MTB I'm currently working on XMC4700, I need to measure an input PWM.
I've found https://github.com/Infineon/mtb-example-xmc-ccu4-capture but this example uses a busy-wait system, it's possible to enable an interrupt generated when a rising/falling edge is detected on the CCU4X_Y pin?

e.g.

MTB configuration:

/* NOTE: This is a preview only. It combines elements of the
 * cycfg_peripherals.c and cycfg_peripherals.h files located in the folder
 * F:/Progetti/MTB_workspace/XMC_App/bsps/TARGET_APP_KIT_XMC47_RELAX_V1/config/GeneratedSource.

}

 

I would like to achieve something like https://github.com/Infineon/mtb-example-xmc-eru-extint but using CCU4/8. I'm not sure if it's possible but with the old MCU generation XE167FM it was a standard practice so I hope there's a way.

Thanks for your support.

Hello expert,

I want to make the baud rate changeable when detect unmatched baud rate.

actually I have asked this question before, see https://community.infineon.com/t5/XMC/XMC4000-How-to-make-UART-baud-rate-changeable/m-p/652860#M14147 

But I met new problem. You see in the code below, the first parameter in function "XMC_UART_CH_SetBaudrate" is defined as constant in library source code. Is it possible that I change the code in library?

XMC_UART_CH_STATUS_t XMC_UART_CH_SetBaudrate(XMC_USIC_CH_t *const channel, uint32_t rate, uint32_t oversampling)
{
  XMC_UART_CH_STATUS_t status;

  status = XMC_UART_CH_STATUS_ERROR;

  if ((rate <= (XMC_SCU_CLOCK_GetPeripheralClockFrequency() >> 2U)) && (oversampling >= XMC_UART_CH_OVERSAMPLING_MIN_VAL))
  {
    if (XMC_USIC_CH_SetBaudrate(channel, rate, oversampling) == XMC_USIC_CH_STATUS_OK)
    {
      status = XMC_UART_CH_STATUS_OK;
    }
  }
  return status;
}

Hi!

 I am using the XMC4800 Relax EtherCAT kit v1 and I need to direct the SYNC0 pulse to P1.14 to visualized it with an oscilloscope.

I enabled the DC from TWINCAT. 

I connected the SYNC0-signal to an output port  following the following procedure:
1. Add a DIGITAL_IO APP and configure it for output/push pull
2. Right click ECAT_SSC APP and select HW signal connections from context menu
3. Set source signal from Not Selected to sync_out0. Set your DIGITAL_IO APP you have added before as the Target.
4. Right click yout DIGITAL_IO APP and select Manual Pin Allocator from context menu. For SYNC0 you can select P3.7 or P1.14.
5. Start code generation and rebuild your project.

The result is: a continuously high signal on pin 1.14.

Can you suggest me something to do?

Thanks in advance.

Hello,

I am looking at the example code and would like to know why is XMC_CCU4_EnableShadowTransfer API called twice

once in the void CCU40_0_IRQHandler(void) {

…

       /* Enable shadow transfer for the new PWM value update */

       XMC_CCU4_EnableShadowTransfer(MODULE_PTR, XMC_CCU4_SHADOW_TRANSFER_SLICE_0);

}

 

and once in the int main(void) {

…

       /* Enable shadow transfer */

       XMC_CCU4_EnableShadowTransfer(MODULE_PTR,    \

                    (uint32_t)(XMC_CCU4_SHADOW_TRANSFER_SLICE_0| \

                                 XMC_CCU4_SHADOW_TRANSFER_PRESCALER_SLICE_0));

…

}

 

Best regards
