Im using the XMC1100 boot kit board, and attempting to toggle the on board leds with an interrupt generated by the CC4 timers. While using the XMClib rather than the Dave Apps. im not 100% sure where im going wrong in my code, and still a bit confused on all of the functions required to get a simple timer , and interrupt generated. Could someone go through my code, maybe point out where im going wrong, and also point out the bare min for a simple timer/ interrupt generation while im learning how to use the CC4?

The current code compiles with no errors, but the LED will turn on, but never toggles, so im assuming the interrupt is never being called.

Code below.

Hi I have a college project about a accelerometer taking measures from X,Y,Z axis and then turning some lights on when i move my accelerometer in those axis. I'm new to XMC and I'm having some issues with I2C in general. I want to receive data and write data, and for now I'm just trying the WHO_AM_I register to see if I can receive some result, but I always get stuck in my while loops.

Work Down here.

Hello Sampath,

Could you please suggest suitable XMC Series Controller Eval Board for controlling 48VDC BLDC Motor for E-Vehicles application. We have Card for Driver and MOSFET side. We just need Controller and reference FW to control BLDC Motor. Please response ASAP.

Hello everyone,

I have a question. Why is there a string of code at the bottom of the chip? How can this happen? Who knows and tells me why???

Look forward to your reply.
Your soon feedback would be appreciated.
Thank you very much.

Best regards,
Qunt Chen

Hi,

I have an issue such that when I play audio via A2DP or have an open SCO connection the HCI UART interface stops working.

When I stop the audio stream the HCI interface resumes operation.

BR,

Oskar
