XMC™

Processor card: KIT_XMC4400_DC_V1 

Drive board:   EVAL-M5-IMZ120R-SIC  board.   

Question:  How to set absolute current limit in software for I-V, I-U and I-W?   

Problem:  we can drive the motor for 2s.  However, the current of I-V/U/W keep increasing.  then trigger the CTRAP ..  

Thanks

Have been running three Ethercat devices with XMC4800 Micro controller, it works perfect. Adding more devices I could get it to work if fourth device is an IO module and the fifth is an Xmc4800 Micro controller but not with more devices.

I have ruled out cabling problems and similar hardware problems since it work perfect with three devices, different devices, different connections and different cables but problem start only then more devices are added. It seems even though message does not arrive back at master, also checked with wireshark values are written to fifth device then checking with debugger.

Then adding more than three devices some error counters increase. I have measured message with oscilloscope it seems device closest to master send message back to master so it seems it get destroyed in some way. Only clue I have is port two is physically connected even though it is not implemented in XMC4800? Anyone else have suggestions? Or got it to work with more devices?

Circuit boards should be ready for small series production, actually already made a few though I have some work left with the enclosure. Show Less

 

I drew a minimum system version of XMC4800 to test this chip. Use DAVE4 software for debugging. The first few days were fine, but suddenly one day, I found that the program could not run normally. Turn on debugging and found that after entering the debugging, the start button is gray, as shown in Figure 1. The pause button is on

After I clicked Pause, I found that the running address was at 0X0000000 instead of 0X8000000. As shown in Figure 2

Then I wanted to check the program at 0x8000000, and found that it was all empty. As shown in Figure 3

Then I changed the xmc4500 microcontroller, and the problem still occurred, not directly damaged, but after several hours of debugging.

Then I changed the xmc4500 microcontroller, and the problem still occurred, not directly damaged, but after several hours of debugging. I removed the chip in question and loaded it on the official KIT board, but the chip still didn't work properly. This gives me a headache and I hope it can be resolved.

Hello everyone,

For one application I want to use 2 TLE493D Hall sensors.

Arduino 1.8.15

1. Some time ago I used a XMC 2Go with the TLE493D library v1.2 for fast prototyping and everything worked fine. Since there is an update to v1.3 it does not work anymore with the XMC 2Go.
Not even the minimal Cartesian example works anymore and I only get -266,24 for the X, Y and Z values.
Resetting the library to v1.2 did not work either.
What is the reason that it does not work anymore?

2. secondly I tried the Infineon TLx_generic_lib for the XMC also for Dave.
The problem here is that TLx493D used abstraction level, then it works, status message = 0 -> I2C_INT_SUCCESS
Example code here:

 

int main(void)
{
	// Initialize Kit
	UART_init();
	INT_init_ext_interrupts();
	I2C_INT_init();
	// please note that the value of status should be checked and properly handler
	int32_t status;
	TLx493D_data_frame_t frame;
	int16_t Bx_LSB, By_LSB, Bz_LSB, sensor_temperature_LSB;
	TLE493D_data_t sensor_state = {0} ;
	float bx, by, bz, temperature;
	TLE493D_AW2B6_reset_all();
	// power-cycle the sensor
	// On the 2Go Kit, the sensor may not be powered by default
	// Initialize the sensor
	status = TLx493D_init();
	// set operation mode to Master Control Mode
	status =  TLx493D_set_operation_mode(TLx493D_OP_MODE_MCM);
	// read a data frame
	status = TLx493D_read_frame(&frame);
	while (1U) {
		// read a data frame
		status = TLx493D_read_frame(&frame);
			// Copy Magnetic Field Intensity and temperature values in LSB format
			Bx_LSB = frame.x;
			By_LSB = frame.y;
			Bz_LSB = frame.z;
			sensor_temperature_LSB = frame.temp;
			bx = (float)(Bx_LSB) * TLE493D_B_MULT;
			by = (float)(By_LSB) * TLE493D_B_MULT;
			bz = (float)(Bz_LSB) * TLE493D_B_MULT;
			temperature = (float)(sensor_temperature_LSB - TLE493D_TEMP_OFFSET) * TLE493D_TEMP_MULT + TLE493D_TEMP_25;
	}
}

 

But if I use TLV493D/TLE493D/TLI493D-W2BW abstraction level, then I can't initialize the sensor. I get as status message the value 3 -> I2C_INT_NACK

 

	// Initialize the sensor
	status =  TLE493D_AW2B6_init(&sensor_state, TLE493D_AW2B6_I2C_A0_ADDR);
	// set operation mode to Master Control Mode
	status = TLE493D_AW2B6_set_operation_mode(&sensor_state, TLx493D_OP_MODE_MCM);
	// read a data frame
	status = TLE493D_AW2B6_read_frame(&sensor_state, &frame);

 

What is the reason? I only go by the example. I can change the address of the sensor only in the TLE493D-W2BW layer.  But if the initialization does not work, then the problem is somewhere else

Best Regards

Michael

Hi,

I am new to EtherCAT and XMC and I was going to use simple IO on XMC4800 Relax Kit V1. I went through the example and was able to successfully control 8 LEDs and 2 buttons on TwinCAT. Now I need to define my own pins (for example using P14.2 for Analog in and Pin 3.9 for Digital) and I am a little confused here. At first I need to edit the Excel file with new names and pins, right? For example attached is what I am going to do. Then should I use the previous xml file and updated excel in SSC tool to create new files? After that I need to edit some codes in Dave which I am confused where to jump to or what to edit. My understanding was I need to change the main.c and XMC_ESC.c (Attached) but I am not sure what exactly need to be modified here. Do I need to add a DIGITAL_IO and ANALOG_IO apps? and how they talk to through EtherCAT app? I really appreciate any help here.

Hello!

I've been working on implementing PTP on the XMC4700, and I'm close to getting the timestamping setup working.  However, I'm quite puzzled by the description of the TIMESTAMP_CONTROL.SNAPTYPSEL bitfield (XMC4700 reference manual page 1212).  It simply says, "These bits along with Bits 15 and 14 decide the set of PTP packet types for which snapshot needs to be taken."  However, I can't find any other mention of this bitfield anywhere else in the datasheet, and there's no explanation anywhere of what the bits actually do.  Could someone provide some clarification on how this bitfield affects the packets that are timestamped?

Thanks!
