我这边使用YTM32B1MC03系列的芯片,有如下两个问题: 1、串口使用外部40M的晶振,当波特率使用921600发送数据,PC端串口工具接收参看会出现丢数据,波特率用115200、230400、460800都是正常的,我用内部80M的晶振时,460800和921600两种波特率都发送都不正常,均出现丢数据。 2、串口调用UART_DRV_SendDataBlocking接口发送数据,超时时间设置为OSIF_WAIT_FOREVER,出现只发送了4个字节,就返回了超时错误
帮助没办法联网的电脑使用YCT
帮助改进和优化YT CONFIG TOOL,有机会抽取YTM32B1ME0 EVB哦...
