[align=center][font=微软雅黑, "][size=14px][align=left]This design uses STM32F407 as the core to achieve isolated current measurement. Use TDA2030 to power amplify the input signal, and the current is tra...
Hello everyone: I need to control a USB sound card via HID. I have successfully opened the USB device and called HidP_GetCaps. But when writing data via WriteFile, there is a problem. The API document...
FPGA software part of the intermediate frequency design of DUC design of PFIR design This scheme requires the design of a 72-order 3-fold interpolation programmable FIR filter (i.e. PFIR), with an inp...
I want to use 430 to measure the number of pulses of an external input pulse in 1 second. I use Timer_A to set the timer for 1 second, and then define the input pin as capture mode. Every time a pulse...
I often see posts about 0 detection, but I don't know what function they want to achieve. Some even cite foreign papers, which are very complicated and difficult to understand. I simulated the attache...
