您好，有沒(méi)有ch32V307VCT6使用外部以太網(wǎng)PHY的例程？

您好，如果是用外部100M的PHY例程本身是兼容的，僅需要將eth_driver.h中的PHY_MODE改為USE_MAC_MII即可。如果是外部1000M的PHY，可以留個(gè)郵箱通過(guò)郵箱發(fā)您。

好的，多謝！

還有一個(gè)問(wèn)題，一般外部PHY工作之前都需要初始化吧，為什么我看咱們的以太網(wǎng)驅(qū)動(dòng)都沒(méi)有這方面的代碼，也沒(méi)有SMI（MDC/MDIO）接口的驅(qū)動(dòng)程序？

您好，程序中通過(guò)調(diào)用ETH_LibInit()實(shí)現(xiàn)對(duì)網(wǎng)絡(luò)的初始化。

還有一個(gè)問(wèn)題，為什么我主函數(shù)循環(huán)發(fā)送UDP幀，一直都發(fā)送不出去，這是為啥？但是接收一幀UDP發(fā)送一幀可以正常實(shí)現(xiàn)

您好，如果是在UDPServer的例程中通過(guò)調(diào)用WCHNET_SocketUdpSendTo()；發(fā)送失敗后len長(zhǎng)度會(huì)被清零，因此下次調(diào)用時(shí)需要重新賦len的值。

如果是在UDPClient的例程中調(diào)用WCHNET_SocketSend();發(fā)送需要在創(chuàng)建相應(yīng)的Socket通過(guò)生成的SocketID實(shí)現(xiàn)數(shù)據(jù)發(fā)送。發(fā)送失敗后len長(zhǎng)度也會(huì)清零，處理方式與WCHNET_SocketUdpSendTo()；相同。

另外再調(diào)試CAN的時(shí)候?yàn)槭裁礋o(wú)法發(fā)送和接收數(shù)據(jù)？？我用示波器測(cè)試PD0和PD1也沒(méi)有波形。

我硬件上CAN1的用的是PD0和PD1。初始化代碼如下。用的是官方的例程進(jìn)行修改

您好，EVT中CAN例程需要搭配CAN收發(fā)器使用，PD0與PD1接CAN收發(fā)器后通過(guò)邏輯分析儀抓到波形如下：

我有外接收發(fā)器，型號(hào)為：TCAN1042

您好，可加我微信將程序發(fā)我，我這邊測(cè)試一下。WeChat：19951759326

您好，我有一個(gè)問(wèn)題，CAN查詢(xún)接收發(fā)送例程中，為什么CAN2的例程都不需要設(shè)置ID過(guò)濾呢？我看函數(shù)里面都是對(duì)CAN1的寄存器操作。另外我通過(guò)什么來(lái)確定，數(shù)據(jù)是接收到CAN_FIFO0還是CAN_FIFO1呢？？

您好，這邊有一個(gè)CAN1與CAN2共用的例程（采用中斷方式接收），您可以參考一下。
