I’ve used this to rsync data files between my Azure (in Microsoft Intranet) and my School Server (in school intranet that requires VPN) using OneDrive as the exchange. I’ll use another blog to talk about this.

Use `aria2c` instead of `wget`

Wed, 20 Nov 2024 00:00:00 +0000

Recently, I need to download the dataset to my remote servers. Clearly, I do not want to download to my local machine. So initially I choose wget as I previous did. Soon after I find wget is too slow. Then I ask ChatGPT. It recommends aria2.

Official Page: aria2

The greatest advantage is it can establish parallel connections simultaneously to speed up the download. We can use

sudo apt install aria2

to install on Ubuntu.

RAK11200 Config

Sat, 07 Jan 2023 00:00:00 +0000

Arduino

Download Arduino
1. To add board support for RAK11200 on Arduino, start Arduino IDE and open the Preferences window (File > Preferences).

Copy https://raw.githubusercontent.com/RAKwireless/RAKwireless-Arduino-BSP-Index/main/package_rakwireless_index.json
Open board manager, type RAK and choose the corresponding board.
Connect Board with USB. You are required to find the port.

To check if it is the right port, plug out and in to see if it disappears/appears.

Remember to check if the connection of wire is good. 5. Short Boot0 and Ground 6. When uploading and showing “connecting”, press the reset for at least 2 seconds.

PAC advance 电机使用指南

整体连接

初始化

首先要初始化调零（即滑块在初始位置时，显示屏上的坐标也在初始位置）

先返回（左下角），进入手动（F2）模式。

可以选择高速（F1）或微步（F2）模式。选择相应的坐标轴左右调整（注意正负）。直到滑块到达零点位置。

**之后，拔掉数据线。**选择程零（F3），可以看到显示屏上的数字被手动调整为0。

最后再插上数据线。

电机编程流程

整体流程：初始化基准点 → 绝对位置（3.4，设置到终点）→ 延时（3.6）→ 绝对位置（回到起点）→ 设置循环（3.9）

$$ v = \frac{L \cdot F}{60} $$

如果设置$F=833$，则速度

$$ v|_{F=834} = \frac{1.2 \times 833}{1000} = 1 : m/s $$
