[分享] NRF52832 Debug 使用 J-link RTT Viewer
- 因為專案的關係需要使用兩組 UART(一組通訊、一組Debug)，但NRF51和NRF52832只有一組硬體UART，所以嘗試了Porting SoftSerial 和 BufferedSoftSerial 這兩個 Library，但測試後各別的 baudrate 極限只有到 4800 和 2400，個人覺得應該是底層 Ticker 使用 32.768KHz …

請教一下，關於 EventQueue 和 Thread 的使用 ....
- 自己研究了一下，dispatch_forever() 就等同於 dispatch(default -1)，內部是一個while(1) loop 用來處理各個Event。 以 mbed 5.x 來說 main 本身就是一個Thread，所以第一種作法只是在 main thread 直接去處理各個Event。 …

有辦法同時使用I2C & UART 嗎?
- 我的程式更新 mbed-os library 後就沒問題了，神奇的是更新的是 I2C Master 端，不是I2CSlave端。 I2CSlave也不需要使用中斷，延時5ms接收也沒問題了。

- 我現在也是卡到I2CSlave 的問題, 用新唐的板子。接收部分 polling時間只要延遲500us，就會收不到資料。目前找到一個舊的library I2CSlaveX, 用中斷接受資料，不過library 有點久，compile不會過，需要試一下。

- 同時用I2C 和UART 是沒問題的，不過我看你的code 用的是I2CSlave… Slave 就有比較多的限制…

Realtek RTL8195AM with PCA9548A
- @Yi-Chun Hung 曾經有遇過一顆IC，好像就是SHT這個系列，忘了是Busy/Ready還是Intterrupt的時候，會把I2C clock拉low，導致I2C bus 上不能並第二顆sensor...你可以檢查看看是不是這類原因影響PCA9548A 正常運作...
