一共就這幾行代碼，每次Read出來都是0XFFFF。 有沒有跟ST-LINK?Utility類似的工具啊，可以外部讀取Flash內(nèi)容，從而先確定是沒寫進(jìn)去，還是讀出問題了啊，函數(shù)接口又都是void類型，完全不知道問題出在哪里。

您好，若你需要讀取FLASH的存儲內(nèi)容，只需要讀對應(yīng)的地址就可以了。附件為CH32V103 FLASH讀操作例程，你可以參考下。注意下，若你在讀之前有解除讀保護(hù)操作，且解除之后并沒有寫入，那讀出來就會是0xFFFF。

我換到標(biāo)準(zhǔn)讀寫了，目前寫入的時候，在FLASH_Lock的時候卡住，出不來。

保存前，禁用中斷，LOCK后再恢復(fù)，目前看效果一樣。

您好，若你是FLASH寫入出現(xiàn)問題，當(dāng)采用快速編程方式時，需要先執(zhí)行快速編程模式解鎖操作，然后再進(jìn)行操作，如下圖。具體可參考我們手冊閃存操作流程和EVT FLASH例程。

我用demo代碼，沒問題。

然后用自己的代碼，就不行了。 用到了ADC-DMA中斷， 外部中斷，F(xiàn)reertos.

EXTI0_IRQHandler中調(diào)用的Flash寫入，為了排除是不是中斷函數(shù)里不能讀寫Flash。 我把代碼加在Main中了

main讀了Flash，不過出來全部是0xFF。? 隨后執(zhí)行寫入操作（標(biāo)準(zhǔn)寫，不是Fast）。 這時候暫停代碼，發(fā)現(xiàn)停止在

您好，我們FLASH標(biāo)準(zhǔn)庫函數(shù)中有多處調(diào)用到FLASH_WaitForLastOperation這個函數(shù)，你可以通過打印調(diào)試的方式看程序具體是停止在哪個函數(shù)里了，若需要，可將例程發(fā)到我的郵箱（lzs@wch.cn），這邊可以幫你看一下
