Configuring the Digispark ATTINY85 board for Arduino IDE and upgrading the bootloader

Warning: this document has to be updated by pointing to https://github.com/SpenceKonde/ATTinyCore

This note describes the configuration of an ATtiny85 based microcontroller development board named Digispark and similar to the Arduino line. It is available in many online marketplaces for roughly 1 dollar (e.g., Ebay, Amazon, AliExpress) and is shipped fully assembled, including a V-USB interface (a software-only implementation of a low-speed USB device for Atmel's AVR microcontrollers). Coding is similar to Arduino: it uses the familiar Arduino IDE and is already provided with a ready-to-use bootloader (

在 Xcode 里下载文件真的是一种折磨, 特别是每次 Xcode 大版本更新都会遇到新的下载内容. 经过一翻周折, 本人找到一个方法可以轻松快速便捷地下载和安装对应的 Simulator 和 Doc 文件

在 Mac 下, 打开 Xcode, 进入 Preference 中的 Downloads 面板
点击任意的下载按钮
打开系统帮助工具 Console
稍等一会儿, 在 Xcode 里取消下载, 然后你会在 Console 里面看到对应的下载地址 (对应的 Cosnole Message 是 (DVTDownloadable: Download Cancelled. Downloadable: ...) 之类的)
复制对应的链接地址, 到某雷或者任何比 Xcode 下载快的工具里
等待下载完成, 进入 /Users/#{Username}/Library/Caches

	Reading the Portable Executable (PE) header in C#
	My job consists of writing fully custom applications for groups of people. The time pressure of these projects is quite high, so generally people start using the application while I’m still writing it, which means I write it modularly and add features as I go along. I also fix bugs as they are discovered. My clients are 2 tiered where expert users get a new build first, they test if for a while, and if they think it’s acceptable they then pass it on to others.

	This method of distribution is quite ad-hoc so when a client rings me up and asks me to view their screen to look at something, it’s useful to know what build they are running. To facillitate this I print the link date in the main Window Title so I instantly have an idea about how old the version is that I am looking at. This date is calculated at run time. To do this requires reading in the Portable Executable (PE) header from th
