Create a downloadable project, and then add the following code, which is the built-in example. I have a few questions about the example program. Can an expert help explain it? Thank you. 1. Where is t...
I want to generate a PWM wave, and use 1.4 1.5 2.4 2.5 to complement each other and be the same in pairs (generate SPWM wave, full-bridge inverter). Now 1.4 and 1.5 are complementary, and 2.4 and 2.5 ...
I recently ran into an old friend who is an experienced analog engineer who designs power subsystems for high-reliability servers. He said that a typical rack-mount board he designs with a width of 19...
During kernel customization, there is a situation where, as long as the catalog is slightly modified, even if the original options are restored after the modification, activesync is very likely to not...
ARM7 44B0, bare metal debugging. During debugging, I found that the code in the IRQ interrupt service routine has operations on the IRQ interrupt disable bit of CPSR, setting or clearing it. After I b...
