JJD的讀書、實作、筆記: 第三個練習（下）徒手移植 FreeRTOS V8.1.2
https://joeljding.blogspot.com/2015/01/freertos-v812.html
第三個練習（下）徒手移植 FreeRTOS V8.1.2. 移植有兩種：移植到從未支援過的CPU（或說不支援的CPU架構）；移植到前人曾經移植過的CPU。 前者困難：與CPU架構、編譯工具相關，但支援種類很豐富[2]。 將 FreeRTOS V8.1.2 下載解開，放在 BSP 目錄裡，跟 FreeRTOS V7.4.0 並排放。見 CMakeLists.txt。 支援的檔案放在 FreeRTOS/Source/portable/[compiler name]/[processor name]。按照文件[2]的建議步驟檢查一遍即可。 1] Creating a New FreeRTOS Port link. 2] Official FreeRTOS Ports link. 3] error: missing binary operator before token "long" link. 訂閱： 張貼留言 (Atom). 四枝筆新單曲出黑膠 聯名 Spinbox 唱盤開放預購.

JJD的讀書、實作、筆記: strtok 在兩重迴圈內的現象
https://joeljding.blogspot.com/2015/03/strtok.html
我有兩個字串 "X,x" "Y,y"，需要各自 parse 並組成 XY, Xy, xY, xy 四種組合。 乍看之下，這個問題並不困難：兩個 strtok 的 while 迴圈，應該就可以解決問題。以下就這樣寫：. 不過，結果不是我心裡想的，xY, xy 都不見了：. Joelding@localhost strtok]$ ./a.out. 重看一下 strtok 的文件（man strtok），strtok 內部似乎使用了 static 的變數，保留了字串的位置，使得下次重複呼叫時，可以繼續 parse 字串。那麼，上面程式使用了兩個 while 迴圈，給了不同的字串，顯然使得函數內部錯亂。 Strtok 的文件還介紹了一種可供 reentrant 的版本：strtok r，應該可以解決問題：. Saveptr , *. 結果還是不對，少了 xy 這一項：. Joelding@localhost strtok]$ ./a.out. Joelding@localhost strtok]$ ./a.out. 43: str2=Y # str2 的內容給更改了，只剩下 Y. Saveptr , *.
JJD的讀書、實作、筆記: linux command stty

Use linux command stty. To setup a port. For example, "115200bps, 8-N-1" can be. Stty -F /dev/ttyUSB0 speed 115200 cs8 -parenb -cstopb. Then, echo/cat can be used on character drivers. Writing to serial port from linux command line link. In this article, the write tried to manually send ascii characters no matter it was printable or non-printable. 訂閱： 張貼留言 (Atom).

程式設計部分: QT是c 的寫的，請問c與c 有何不同? Ans:c 具有物件 繼承 封裝 同名義是，個別在詳細說明一下. 邏輯DEBUG:程式沒問題 但硬體不聽你操作 如何debug，. Socket:為什麼socket server要用while連線 不是連一次 就可以. Ans:被打開時 touch一個file在nfs資料夾中 QT會去打開此檔案 看是否開的起來. Ans:沒有，架構上有參照，但因為硬體連接的腳位已和當初不一樣 必須要修改暫存器的address. 2 本部門做IPMI，遠端伺服器管理，用網頁或者ap介面即時監控遠端cpu 風扇 記憶體的狀況. 3 3個月試用期 給你小工作 跟專案有關的 讓你修改部分功能. 訂閱： 張貼留言 (Atom). Wikipedia - Recent changes [en].

patrick blog: arm7加入inetd和telnet ,設定baud rate
http://patrick0703.blogspot.com/2009/02/arm7inetdtelnet-baud-rate.html
Arm7加入inetd和telnet ,設定baud rate. 用custom vendor = network application = inetd. 終端機的baud rate跟arm板晶片的baud rate都要設9600 或 115200才能傳送資料過去. 程式中要設定115200 baud rate 公式可看date sheet :115200=x/16(dividsor 2),x已知. 所以dividsor 算出後是10進制,再轉成2進制,寫到暫存器中. 訂閱： 張貼留言 (Atom).
