单片机运行时的数据都存在于RAM（随机存储器）中，在掉电后RAM 中的数据是无法保留的，那么怎样使数据在掉电后不丢失呢？这就需要使用EEPROM 或FLASHROM 等存储器来实现。 插播一段：ROM最初不能编程，出厂什么内容就永远什么内容，不灵活。后来出现了PROM ...

部分MCU片内不带程序存储器ROM，可执行代码只能放在外面的EEPROM、FLASH(外扩)中； 单片机对于数据的处理和系统的大量数据采集，需要考虑数据的长期保存和掉电保存等问题，因此外扩EEPROM就是这系统常见的模块。外扩的EEPROM也可以用来存储一些参数，保存一些 ...

The Raspberry Pi 5’s processing capabilities have received a significant boost thanks to the EEPROM update’s enhanced overclocking support. Users can now push the device’s performance to new heights ...

I previously wrote a series of articles about my experience flashing a ThinkPad X60 laptop with Libreboot. After that, the Libreboot project expanded its hardware support to include the ThinkPad X200 ...

The firmware included with the Raspberry Pi 2 Model B version 1.2 introduced the possibility of booting from a USB device: before that, it was only possible to boot from an SD or microSD card. But ...

The Raspberry PI Foundation has released beta firmware and a bootloader to enable booting the Raspberry Pi 4 from a USB mass storage device. The new firmware and bootloader could be useful to ...

I cannot believe how simple it is now to get a Raspberry Pi 4 running from an SSD rather than from an SD Card. I have written what to do here, because the web seems devoid of a simple list of ...

The microcomputer designed to get kids interested in coding powers down when hit with high-intensity, long-wave flashes from cameras. CNET contributor Don Reisinger is a technology columnist who has ...
