GPIOs and Go

Recently, I decided that I needed a small heads up display for import things I kept forgetting, like the time until an event started or number of unread emails in my inbox. I wanted the display to be simple and bright so it would really catch my eye. I naturally started to look at seven segment displays. Four digit, seven segment displays are available in most hobby electronics stores and come in a variety of packages. What is most noticeable when comparing these packages is that the 12 pin, analog package is significantly cheaper than the packages with bus interfaces (UART, SPI, I2C, etc.) and less pins. I wasn’t using the majority of GPIOs on my Raspberry Pi Zero and being frugal, I decided to buy the analog package. What happened next was an exploration into how Go can quickly control GPIO pins to make the display actually work well.

【分享】升级Vivado工程脚本

Vivado可以导出脚本,保存创建工程的相关命令和配置,并可以在需要的时候使用脚本重建Vivado工程。脚本通常只有KB级别大小,远远小于工程打包文件的大小,因此便于备份和版本管理。 脚本里指定了Vivado的版本、器件的型号,IP的版本。如果导出脚本时的相关版本,和恢复工程时的相关版本不一样,会导致创建工程失败。可以通过手工检查和修改相关版本信息,升级Vivado工程脚本,使新的Vivado也能恢复出对应的工程。 目前我电脑中只有Vivado 2020.2。但是得到了一份Vivado 2020.1为开发板vck190 es的创建的工程脚本。下面以把前述脚本升级到Vivado 2020.2为例,讨论如何升级Vivado工程脚本。
