Also in the simulation section, I saw a friend post a master's handwritten copy. So, in the process of learning, have we ever had our own handwritten copy? Or a record of solving a certain problem. Le...
Let's use an abacus as an example to solve an arithmetic problem. Example: 36 + 163 × 156 - 166 ÷ 34. Now to do the calculation, we first need an abacus, followed by paper and pen. We write down the p...
I have a DSP experiment board. Flash is the DSP off-chip memory. I encapsulate the written program (such as GetVal(), etc.) into a lib file, download it to the flash chip, and then load a program in o...
