DAVE™ Forum Discussions

Hi all,

I am planning to use the E_EEPROM_XMC4 App to store a non volatile variable in FLASH memory. The variable will be written once in the product lifetime (it is a license key)

Is it possible to protect the variable from being over-written while updating the firmware via flash programming when using a a programming tool like XMC-Link / XMCFlasher or Mini-Wiggler / DAVE IDE

In other words how do I locate the variable in a location that flash programming won't reach.

Thank you in advance

Hi there,

The 'CAPTURE_Init' function causes an immediate capture interrupt even though the configured input pin does not change state with the resulting measured frequency of 3 Hz. This appears to be a bug in the DAVE CAPTURE APP.

My CAPTURE APP configuration...

• ‘Start after initialization’ is ticked
  
• ‘Enable capture event’ is ticked
  
• 
  

In my case the 'CAPTURE_Init' function is being called via the 'DAVE_Init' function

Also no function seems to be available to configure the interrupt enable, only the ability to start & stop the capture timer.

Any help would be much appreciated

Hello,

is there a possibility under Dave to set the baud rate below 100kbps in the CAN_NODE_0 register/General setting? for example 20kbps

Hello team,

I am using XMC4800. How can I print the buffer data out, in the debugger command console?
I tried directly put command " print buffer " in the console. It works but when I put this command in the breakpoint actions, there is no ouput on the debugger console.
Is there any other solution to print out a large buffer data (greater than 100) in one go?

Thank you Show Less

Hi everyone,

Is it possible to display the execution time of sections of code within DAVE 4 ?

For example the time to execute a function.

Thank you very much

Hi,

I posted this issues on the XMC Forum a few days ago, but since I haven't received any responses, I figured I might have posted in the wrong forum, so I'll here as well (btw, I'm very new this forum and products).

I just bought an OPTIGA Trust XMC 4800 IoT Connectivity Kit, and have just started going through some tutorials, such as for DAVE.
There's a DAVE QuickStart Guide for how to make a LED blink using a generated PWM signal. I follow the instructions, and have tried to use both the
"XMC4800 IoT Connectivity Kit" under Boards, as well as the XMC4800-F100x2048" under the "XMC4800 Series" option, but in both cases neither P4.0 nor P4.1
are available when I try to assign the PWM output (these are LED pins on the board). Has anyone encountered the same problem?

Thanks! Show Less

Hello everybody,

I would like to connect the board BLDC_SHIELD_TLE9879 with an XMC microcontroller to control a BLDC motor.

Is there an example for the DAVE development environment?

Thanks in advance.

hello

I can not English.

so, my write is grammar is wrong.

today use Dave tool.

so, im beginner.

i question.

void dma_init(void)
{
/* DMA Source/Destination Address setup */
pDMA_src_I1 = (uint32_t*)&ADC_MEASUREMENT_ADV_G1_IF1_I_RES;
pDMA_src_Q1 = (uint32_t*)&ADC_MEASUREMENT_ADV_G2_IF1_Q_RES;

pDMA_dst_I1 = (uint32_t*)adc_i1;
pDMA_dst_Q1 = (uint32_t*)adc_q1;
}

xmc4200 chip

IFI.LG or IFI.HG is P14.0 or P14.4

but, ADC_MEASUREMENT_ADV_G1_IF1_I_RES is 0x40004400->RES[15] ?

I understand => 0x40004400->RES[0]

Add to

I can't understand

Dma init

Simply Explanation please.

I updated my library last week. Now when I add SPI Master App I get errors.
SPI Master version is 4.3.26
It is the desired bus speed that is causing error. It is s usual set as 19.2 as default. Which gives you a pop up error.

"Entered value is not in range [0.1, 0.0]."
"Control will be updated with last saved value"

Those values are of course not correct. a bus speed of 0.0 KHz would not work very well.
I have tried creating a new workspace with a new project and just addin SPI Master and still get the bug.
Any workaround?

I went back to version 4.3.24 for now. That seems to work. Show Less

Hi all,

I am calling the sscanf function in my code but DAVE 4.3.2 ignores the %X specifier for interpreting Upper Case Hexadecimal input characters.
