Recently, I made a TFT screen SPI driver. Since the MISO pin is not used for unidirectional data writing, the SPI is configured as SPI_Direction_1Line_Tx mode. However, when debugging, I found that th...
Capacitive touch technology has been used in kitchen appliances for several years, for example in ovens and frying pans, with discrete buttons behind opaque glass panels. These touch controls have gra...

The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
