Hi everyone,

The PWM App does not allow CCU8 to be selected in DAVE 4.3.2 although the App Help states that CCU8 is an option.

Is this just a documentation error and PWM_CCU8 is to be used instead ?

Thanks very much.

Hi everyone,

• I am running DAVE v4.3.2 and the 'ENCODER_POSIF' APP is missing.
  
  
• If I check for DAVE APP updates the 'ENCODER_POSIF' does not appear in the 'APPS Library Update Page' either.
  
  
• How can I obtain the 'ENCODER_POSIF' please ?
  
  

Thank you very much

Hi all,

Would anyone know the purpose of the 't_offset' parameter in the following function please ?  It is not documented the v4.0.6 App help.

    ENCODER_POSIF_GetRotorAngle ( ENCODER_POSIF_t *const HandlePtr, uint32_t t_offset )

Thanks very much

Hi,

DAVE App of EVENT_GENERATOR for ERU has only single "pattern" input, it has no "tout" output.
XMC1400 ERU has 4 inputs EXICONx.FL to detect pattern, and ERU_TOUT as "tout" without gating.

Why does not the ERU_GENERATOR of DAVE App have "tout" ?
Would you modify the ERU_GENERATOR to have "tout" ?

Best Regards,

Hi,

I have an IMU which uses I2C for configuration. The device uses only one byte writing, meaning that the master may transmit only one byte of data to the slave and then the stop condition must be sent by the master.

The slave's address is 0xA (and according to the app description, the value shall be left shifted by 1 bit to make room for the R/W bit, therefore the value of the address define is 0x14), the register address and the content to the written to it are defined in variables. I am also using the NACK received callback function. I am always receiving a NACK signal and am not sure why. Perhaps I am using the transmit function incorrectly? The relevant code is attached below.

Regarding HW problems: the IMU used is not dead, the electrical connection between the master and the slave is fine and the baudrate is also within the device's specification.

void NACK_Received(void)
{
	I2C_MASTER_AbortTransmit(&I2C_MASTER_0);
	I2C_MASTER_SendStop(&I2C_MASTER_0);
}

// configures the IMUs used for our project
static void configIMUs()
{
	uint8_t config[2] = {ADDR_ACCEL_RANGE, 0b00000011};

	I2C_MASTER_Transmit(&I2C_MASTER_0, true, IMU_ADDR, config, 2, true);
	while(I2C_MASTER_IsTxBusy(&I2C_MASTER_0));
}

 I have looked at the code example provided for the transmit function and I believe my implementation above does the same thing. Firstly, the start condition is sent, next the slave address, next the two bytes of data (first the register address and next the data to be written), and finally the stop condition.

Thanks in advance for any advice

I know I'm not the only one who was having this issue; having to kill and re-launch DAVE to get it to load my project without locking up.

Recently the IT department changed my installed antivirus from Sophos to SentinelOne, and the freezing has gone away! Also my builds are faster.

Just putting it out there in case anyone is interested.

Hello!

I encountered some problems.
I am trying to figure out how to transmit / receive data from/to a XMC2GO board through UART, using DMA Transmit Mode.I uploaded the UART DAVE APP and configured it as shown in the Usage section, then I tried changing the transmit mode to DMA, but I am not sure what I am supposed to change.
As you can see in the image attached, simply by modifying the UART App Settings you cannot change the transmit mode to DMA (you need to do it using GLOBAL_DMA app, as stated below).
I changed :

UART_0_config.transmit_mode = UART_TRANSFER_MODE_INTERRUPT,

UART_0_config.receive_mode = UART_TRANSFER_MODE_INTERRUPT,

However, I can see that I need to configure transmit_dma_config, receive_dma_config and GLOBAL_DMA_t * global_dma (structure definition that should be found in "GLOBAL_DMA/global_dma.h").
I don't have generated "GLOBAL_DMA/global_dma.h", so I tried to figure out what to do. I saw in the UART APP documentation that for DMA transmit mode I need to use the GLOBAL_DMA APP, but unfortunately it is not available for XMC2GO, although it has a XMC4200 integrated and the XMC4200 board has the GLOBAL_DMA APP available.

UART APP Documentation snippet : 

 If either transmit mode or receive mode is 'DMA', then the GLOBAL_DMA APP will be used for configuring the DMA interrupt node.

I succeded doing it using Interrupt Transmit Mode, but i need to do it using DMA.

Can you provide me an example for configuring UART DMA data transfer using an XMC2GO board?

Thank you so much!

In a previous discussion   Cannot connect to http://download.eclipse.org/releases/neon/   Freanky asked about connecting to Eclipse Marketplace Client. To take the discussion a step further, I have tried the steps mentioned and can get the Marketplace client to appear on the menu. However, when I click that item I get the error detailed below. I have tried as many of the available remedies as I can, with no success. It appears that the marketplace client obtained from https://download.eclipse.org/releases/neon/201705151400/ requires a http connection while the eclipse site requires https and the two are incompatible. Is there a workaround, update, or anything that could get me access?

Hi 

I want to debug my project on DAVE4.5 (microcontroller XMC4800 ) by use DAP mini wiggler v3  any one know how to config it ?
