Hi,

I was going through document AN2358 which suggests an approach to implementing a Manchester decoder.

I have a query about the implementation.

IEEE 802.3 Ethernet standard states that the input data (Manchester encoded) may have a jitter of +-18ns. Now if this is used in a decoder with a fixed delay count (3/4) to sample an input data bit, how will this circuit sample the correct data and produce the recovered output?

Is there any other way this jitter in the input data can be handled to recover the correct data bit?

Thanks

Hi,

after flashing (iROM) the LCDDemo provided by the Free Aurix Entry Toolchain, the TC2X7 V1.0 Application Kit Board is performing an reset within an second after every startup of the application. Therefore i can't flash the board by the Toolchain anymore, because no connection can be estabiled or the board is disconnected after the board resets.

Is there any possiblity to halt the board after the startup and stop the execution of the the application code e.g. by an hardware pin, so that i can erase the application code or flash a new one?

I'm thankful for every hint, which could lead to an solution of my problem!

Best regards

What's the different between infineon's CAM sensor TLE4983, TLE4986, TLE4988, TLE4931?

Thanks

I am getting above error while programming CY8C6245LQI-S3D42 using miniprog-4. There are 2 boards giving same problem. These boards were programmed earlier.  Also the programmer setup is confirmed working using another board.

Can anyone help to resolve this issue?

Hi

I have downloaded the XMC flasher tool, and when I opened it and tried to connect for the first time I was prompted that there was a new version of the firmware, so I clicked install. But I think somewhere in the installation process it failed, so now the XMC1300 wont connect anymore. I have tried to connect to it using Memtool, but without success.

I have selected device name as 1302-200 (as stated on the chip) and I have selected the connected emulator.

The error log in the XMC flasher is:

What can I do to re-flash it?

I have attached an image of XMC flasher

I can program the psoc5 using openocd now, with some caveats. However, if an NVL entry exists, it stops.

I have a project which somehow did something to the NVL.

I understand setting the Reset condition on the Pins can cause this.  However, setting the pins to Don't Care doesn't fix this problem, so I suspect something else is causing the NVL to change.

Is there *any* gui / command line interface to find out what is causing the NVL to be set? (so it can be "fixed" in the project?)

This would not normally be a problem, but using openocd to program the psoc halts when the NVL entry is in the Creator generated hex file.  I have multiple reasons for using openocd, some of which involve production machines. Others are very fast compile/debug cycle.  (https://socmaker.com/?p=1004, and https://socmaker.com/?p=1027)

If I use objcopy, could I exclude that from the elf file for the new obj?  (before making a hex file) If so, would it be by address? If so, which address?  otherwise, how would I do that exclusion?

Is there a way to use openocd to program the NVL (perhaps kitprog in kitprog mode?) (Just checking)

Thanks!

Hi,

starting from the examples MCMCAN_1_KIT_TC375_LK and ADC_Single_Channel_1_TC375_LK I have to send the value acquired from the analog channel with a CAN message. This is how I've tried to do that:

Hello everyone, I use MCU that has 3V3 output and 5V input tolerant pins, but for my application I need to have 5V output and 5V tolerant input pins. How can I achieve this? Expander is not in the option because it needs SPI/I2C drivers in firmware, and I want to avoid that. I can make 3V3 pin output into 5V pin output using MOSFETs but then the input part is tricky. 
Thanks in advance !
