Radio Frequency Identification (RFID) will be the first emerging technology to coexist with barcode technology and eventually replace it in the field of low-cost identification and personal data stora...
I am using Keil uVision4 and ULINK2. After compiling correctly, a window pops up during debugging: JTAG communication failure! After clicking OK, an error message appears: Target DLL has been cancelle...
I am using f100 SPI to receive data. The waveforms of SCK, MOSI and MISO are normal. Why does the program go into an infinite loop at while (SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_TXE) == RESET);? I...
Asking a question for someone else: I would like to ask you a question. I want to use the Hall sensor combined with the microcontroller to measure the speed of the rotating wheel. I only need the micr...
