I don't have one of these boards, so I can't be sure of this.
Thanks for answering. The charge-pump works with the charge-pump rt component into hal, i just wanted to gain some suggestion on using a dedicated new thread or if it's ok to use base-thread. Following your memory, i'll try to use also a different period for the charge pump. let's say 10kHz, that is my base-thread.
