Let me share some information about the general configuration of IO pins when STM32 is in low power state.
1. Configure unused GPIO inputs as analog inputs
A GPIO always has one input channel, which c...
STM32 uses an internal oscillator. When debugging the code that used to work, I found that it always died in the HAL_RCC_OscConfig function of the stm32f0xx_hal_rcc.c file. The following code was repe...
Preface
I have never used silicon chips before, and I know nothing about this brand. I remember it was a gecko logo. I was lucky enough to participate in the review this time, so I started to understa...
Question 1: When performing trigonometric operations, which method is faster? I am currently using cossp in c67fastMath downloaded from the official website, but the time it takes is about six times t...
Because the STM8s analog input io defaults to floating input, I did not configure the io, but directly configured the ADC. In short, the ADC single-shot mode only collects the signal once and then no...[Details]
