Memory is a key component of any microcontroller-based embedded system. For example, developers need enough RAM to store all volatile variables, create buffers, and manage various application stacks. ...
I am currently playing a video of 320*240 or above under wince5.0 and then closing the software. The system will crash, but not 176*144! I now change the video content and only display a picture. I st...
I have seen that the 64-pin STM32 does not have a reference voltage input terminal. What should I do if I need a more accurate reference voltage? If I use a high-precision power supply to power the an...
I use printf in CCS to send the voltage sampled by ADC to the serial port. I want to use the method of redefining putchar, but the compilation fails. How can I solve it?...
I have posted two summary articles after registering. When I posted, I was prompted "Because the content contains links, it needs to be reviewed", but I failed to post successfully both times. I don't...
Now I want to make a PDA, and I want to use a lithium battery to power 3.7V or 4.2V. Now I have to step down the voltage to power the ARM (3.3V/1.3V), the peripherals 3.8V/5V, etc. By the way, do I ne...
Medicines are special commodities. If patients are given the wrong medicine, fake medicine, inferior medicine or expired medicine, it will pose a threat to people's health and lives.

Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Preface
In recent years, many compact portable electronic products have been developed, such as mobile phones, digital cameras, MP3, MP4, PDA, GPS and DVD, etc. They are not only small in size...[Details]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
Most
embedded
systems are powered from a 48V backplane. This voltage is typically stepped down to a lower intermediate bus voltage of 24V, 12V, or 5V to power the circuit board racks withi...[Details]
