10 Essential Circuits for Mastering Microcontrollers

Source: ICisC Nanjing Integrated Circuit Industry Service Center 1. Choosing Pull-up Resistors for Microcontrollers As can be seen in the reset circuit, when resistor R1=10k, RST is high, but when R1=50, RST is low. It is clear that R1=10k is incorrect, as the microcontroller remains in the reset state and cannot function at all. The … Read more
