When using serial port communication on the stm32 development board, the following error is displayed after compiling the program. ..\USART.axf: Error: L6218E: Undefined symbol __vfscanf_char_file (re...
I recently disassembled a thermal imaging camera from BMW. The FPGA inside is ALTERA's EP3C25U256A7N. I want to try to reverse engineer the PCB and directly develop on this FPGA. The PCB seems to have...
"3.3.2 SysTick" in the article "How to upgrade from STM32F10xxx firmware library V2.0.3 to STM32F10xxx standard peripheral library V3.0.0" says:The SysTick driver has been removed from the standard pe...
I used DDK to make a USB driver, which can communicate normally. But when writing to Pipe1 port in a loop, the driver stops responding after several times. When debugging, I found that it stops at sta...
I have played with DSP and M4 before, but I don't know how to transfer to FPGA. I can't even understand the schematic diagram... Why does an FPGA have to be divided into so many modules......
I have the hardware circuit diagram, and I need the program, which can be written in assembly or C language. Please help me, if you are interested, please contact QQ: 226600569. Very urgent! QQ online...
The circuit shown in the figure is a three-digit tachometer used to measure low frequency signals with a repetitive time interval of 0.235 to 15 seconds. The tachometer has a speed range of 4 to 255 r...[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Magnetic resonance imaging (MRI) systems for medical and scientific applications require a high-performance, high-power inductor capable of establishing a uniform, strong magnetic field. Transverse el...[Details]
Safety is the top priority in the production process, especially for dangerous operations. When the high-voltage line is shut down for maintenance, it is necessary to follow the regulations of powe...[Details]
Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
In a Class D audio power amplifier, the preamplifier is a relatively important module. It is located at the front of the entire topology and completes the processing of the input signal source,...[Details]
