我有兩個 Ubuntu，一個是 18.04，另一個是 20.04，我的 Arduino 板也有一些問題，我已經嘗試過這說明（引腳連接和...）：
但是，Arduino IDE無法偵測到具有Arduino的STM32f013c8t6板，所以我嘗試使用以下命令找到連接埠的USB連接這發布其答案的命令，如下所示：
sudo usermod -a -G dialout $USER
ls -al /dev/USB*
ls: cannot access '/dev/USB*': No such file or directory
並透過嘗試其他一些帖子說明：
lsusb

Bus 001 Device 005: ID 0bda:0821 Realtek Semiconductor Corp.

透過 triglsb -v -d命令我得到以下結果：

因此看不到已透過 snap 安裝的 Arduino 上的連接埠連接，如下所示：
另外，嘗試以 root 使用者身分執行 Arduino，但出現以下錯誤：
sudo arduino

所以我認為這不起作用，因為透過 snap 安裝 Arduino 並透過sudo snap connect arduino:removable-media命令修復它，但我 mkdir: cannot create directory '/run/user/0': Permission denied再次收到錯誤，所以我在這裡問：
更新1：
基於第一則評論我嘗試了sudo journalctl -f並得到以下結果:
sudo journalctl -f

我還安裝了最新的 Arduino 版本這個連結並且正在通過sudo arduino命令運行，但直到出現這個問題！
更新2：
很奇怪我看到了下面的貼文這就是說ST-link V2程式設計器可能偽造的並有一些錯誤的引腳連接，如果可能的話我想問，如果我改變的話會發生什麼2,4,6基於該帖子的引腳配置？如下圖所示：
更新3:
我已經檢查過ST-Link V2並且引腳標記正確。所以問題不是出自錯誤聖聯引腳系統！謝謝。
答案1
基於諾伯特評論，據說這個問題是由Arduino的snap版本存在的這裡:
所以我做了以下步驟：
1-我已經安裝了最新的Arduino版本這個連結。
2-基於這個文件，我已經安裝了STM32CubePrg
3-選擇以下設定和程式碼進行測試：
#define LED_BUILTIN PC13
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(2000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
4- 將 FTDI 板連接到電腦以刷新引導程式之前，將 BOOT 0 接頭從「0」位置切換到「1」位置，如上所述這個視頻從這篇文章：
感謝。
