This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as constant in the Flash memory to another buffer in the RAM memory. The received data are stored in the DST_Buffer. The DMA channel transfer complete interrupt is enabled to generate an interrupt at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED

基于UDP實現E-Mail傳輸 工作過程描述： 客戶端描述： 1． Client（以下簡稱C端）端將郵件以規定的大小封裝為符合要求的UDP包。 2． 將封裝好的UDP包發出，并等待Server(以下簡稱S端)端收到相應的UDP包后返回的回應Acknowledge(以下簡稱為ACK)。若收到的為Positive ACK,則繼續發包；若收到的為Negtive ACK,則將應發的包重發。 3． 直到C端將所有要發的包都發完，并都已經收到S端的回應，最后發一個End包，直接關閉此進程。 服務器端描述： 1． S端啟動服務進程，并監聽相應端口。 2． 若收到C端發出的有關請求，按如下情況給出相應的反映： a． 將收到的包進行檢測，若收到的包有錯則拋棄（discard），并發給C端一個negtive ACK。 b． 將收到的包進行檢測，若收到的包正常，則將此包進行解包，將內容輸出至一臨時文件；并發給C端一個positive ACK。 3．依次收到來自C斷的包，直到收到end為止，并關閉此進程，轉回監聽狀態。
