Thanks for your reply, clive1.

Could you please give some advice?I'm dealing with my discrete PI controller for my battery charger. I used a Text LCD to display a valuable calculated by the controller, but sometimes the variable changes too fast or the LCD misses its displaying. I thought I would have used the DAC for the variable so that I could see it in oscilloscope. But now I realize that the STM32F401VC Discovery Kit doesn't feature DAC. I'm thinking probably I could use the Audio CODEC instead, but I find it quite complicated because there are too much things.Could you give me some advice? Just about what features other than DAC that STM32F401VC has that I should work in to meet my monitor purpose.Thank you much for that.P/S: My project is totally for research purpose, not for commercial.

Could you use a TIM in PWM mode? Or output diagnostic/debug data via a serial port, or SWV channel?

@@ Why I didn't think about that?! TIM in PWM is most familiar with me. You make my day. Thank you very much for your advice!!
