This paper introduces an automatic charger circuit for mobile phones and electric bicycles. It eliminates the complex IC circuit and its peripheral circuits, and can also complete the function of auto
Following the HT46R23 and HT46R24, Holtek Semiconductor has launched the HT46R232. This version combines the features and advantages of the HT46R24, which provides more I/O pins and PWM output, with t
Design idea: stm32 uses TIM2 to realize external pulse counting, and button 4 acts as an external pulse. Expected experimental phenomenon: LED3 is off, the serial port outputs the number of pulses (th
Abstract : Analyze some source codes in Boot ROM, focusing on IAP function and the relationship between ISP and IAP; use IAP function to convert the remaining program space into data space, and write
A microcontroller is an integrated circuit chip that uses ultra-large-scale integrated circuit technology to integrate a central processing unit (CPU) with data processing capabilities, random access
