It is very convenient to use printf to send data in the STM32 serial communication program. However, there are always problems when you first use it. Here are some configurations you need to do to use
The Nand Flash model on the development board is K9F1G08U0B. The chip manual says the read data should be EC F1 00 95 40, but I read EC 40 00 EC 40. My project is at http://cache.ourdev.cn/bbs_upload5

Optimizing power consumption is an important but often elusive design goal for digital signal processor (DSP)-based systems. Today, DSP-based devices often combine multiple applications that were prev
