[讨论]串口转以太网调试
各位大侠好:
小弟最近在调试串口和以太网通信实验时,遇到一些问题,请帮忙解释一下,谢谢!
在从UDP到COM的传送过程中,无任何问题,一切显示正常;
但在从COM到UDP传送过程中,老是出现包丢失的现象,比如第一次发送"com_test" 只能收到com,在第二次发送完接受时才能收到余下的部分,一直都是这样收发下去……
为了协调两者的通信速度,我试着添加了taskDelay()函数,缓解了一下以上问题,但是残留的是,在最初两次收发时还是以上问题,但在第三次及其以后收发时就正常了,百思不得其解……
串口波特率115200,以太网10M/100M自适应!
各位高手有没有好的解决办法,请指点,谢谢了!
