Hello everyone,
I am trying to acquire a voltage with my XMC4500 Relax Kit and then transmit the value through USB.
I am using the ADC_MEASUREMENT app activated every 1s by a TIMER app and it works fine. Then I have problems with the USB transmission.
I am using the USBD_VCOM app and I understand that the problem is the type of the value to be sent.
For example, if I try to send the character 'a' by writing
I properly see the character 'a' on my Putty terminal.
On the contrary I did non understand how to send numbers up to 4096. Although I think that only few lines of code are missing, I tried different already posted solution with no success.
Can you help me?
Emanuele
