Hello friends: I have a Bosch infrared passive detector. When the alarm is triggered, it outputs a disconnected switch signal. I want to use this signal to control the speaker to send out an alarm sig
The square wave signal has a low voltage of 0V, an amplitude of 3.3V, and a frequency of 1Hz to 2MHz. How to use analog circuits plus FPGA to measure the rise time of the square wave's rising edge?
KylinlinkDIY This DIY mainly introduces a digital remote control of a flight control system, with the openpilot's oplinkmini as a reference. The main tasks are as follows: 1) Add RF modules with 100mW
