Many ASIC peripherals now use DDR (II) SDRAM (SRAM). Due to the high data transmission rate, data signals are basically source synchronous. Many timing materials believe that there is no length limit
I have been using FPGA to make a digital clock these days, using six digital tubes for display. I used a 20M crystal oscillator and divided it to get a 1KHZ signal, and used this signal to scan the bi
I use lithium batteries to power a microcontroller through a switching step-down power supply to collect data from a vibration sensor. However, the noise from the power supply always affects the data
I write an identifier to the physical sector of a USB flash drive through a filter driver I wrote. I write it starting from the first digit, for example "asdd12344". But sometimes for some reason, the
