There has been a rumor circulating that the STM32 hardware I2C design has bugs, and it is better not to use it, as software I2C is more reliable. For a long time, to avoid unnecessary trouble, I have never used hardware I2C, mainly because software I2C is also quite convenient and can be used on … Read more
I'm Lao Wen, an embedded engineer who loves learning. Follow me to become even better together! Memory is divided into two main categories: RAM and ROM, and this article primarily discusses ROM. Initially, ROM could not be programmed; it retained whatever content it was manufactured with, making it inflexible. Later, PROM was introduced, which could … Read more
