This is a fundamental choice that affects system architecture, performance, cost, and reliability. To better understand the core differences, we can use a metaphor: eFlash MCU is like a laptop with a massive built-in solid-state drive (SSD). All data and the operating system are directly integrated on the motherboard, providing extremely fast access, ready to … Read more

When the MCU code crashes, first determine whether the current stack being used is the MSP (Main Stack) or the PSP (Process Stack). After an exception occurs, the stack order of the ARM core is as follows: R0-> R1->R2->R3->R12->LR->PC->XPSR The LR (R14) register is the link register, which stores the exception return value EXC_RETURN where … Read more
Electric two-wheelers, as economical and environmentally friendly short-distance transportation tools, have penetrated personal commuting, food delivery, and shared transportation sectors. Under the implementation of new national standards and the wave of intelligence, their core control systems must balance efficient power output, safety protection, and range optimization. In traditional solutions, the controller, as the “brain of … Read more
