Hello, I've a receiving problem with the ASC1 serial interface of the XC164 during debugging with ULINK interface. I use the Infineon Starterkit. Transmitting is'nt a problem and if I program the software to flash, and start them without ULINK interface connected, also receiving works. So I believe, it is'nt a problem with register settings. If I use a scope and inspect the signals on JP401, I see a signal, that works against the MAX232 driver. This signal comes from JTAG interface and seems to be the TCK. In documentation of XC164 I red, that these signals are only activ, if the /TRST is asserted. Is there a workaround for this behavior, that I can also use ASC1 during debug process? Steffen
Thank you for this information, Stefan. I can debug my code with ASC0 and then I hope, it will run with ASC1. If you can remember, I got the serial EEPROM code from you. It is running very fine and I optimized the speed a little bit and now I have a good library for this device. Thanks to you, By Steffen
Hi Steffen, thats the right way ! ;-} Cool - I will wrote a SPI-library too, if have some more time, since the timings was very relaxed. But nice feedback, that all works fine for you. Best regards Stefan
