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

Explaining RS485 Transmitter Crosstalk Issues and Solutions

1. Signal Crosstalk Crosstalk refers to the coupling phenomenon between two signal lines. Due to the close spatial distance, there will be unwanted inductive and capacitive coupling between the signal lines, leading to mutual interference. Capacitive coupling can cause coupling currents, while inductive coupling can cause coupling voltages. This is a tricky issue in circuit … Read more
