This is the first time I use stm32, the chip is STM32F103CBT7.
The working process is: at fixed intervals, an external interrupt will wake up the CPU for measurement, store the data in the on-chip fla...
1. Concepts of several frequency bands/points in RFID systems The receiving range of RFID readers is affected by many factors, such as radio frequency, size and shape of tags, energy of readers, inter...
In CCS programming, if we do not specify the storage location of variables/codes, the compiler will automatically assign a location to the variables/codes. However, if we need to put variables in a sp...
Some problems in FPGA design? 1 Several basic concepts in digital circuit design: 1.1 Setup time and hold time: Setup time refers to the time when data is stable and unchanged before the rising edge o...
