PrefaceFirst of all, I would like to thank eeworld and GigaDevice for providing this trial opportunity. I have used GD32F103CBT6 in previous projects , and the development was quite smooth, but power
As shown in the figure above, refer to the information on the Internet. If you want a circuit with an input of 2.5V-12V and an output of 2.5V, the circuit implementation principle is: after power-on,
From the above figure, we can see that the cortex-M4 has a Floating-Point Unit (FPU) and DSP more than the previous generation cortex-M3 .
1. DSP must be supported in cortex-M4.2. FPU is an optional f
Use TIMER for precise timing, select TIMER5 , use single pulse mode, count up, use TIMER5 update interrupt, the initialization function is as follows:In addition, you can set the following function to
