我看到参考设计中,CP2105的The enhanced COM port is the application/user UART and the standard COM port is the data port.,我实验发现The enhanced COM port用于the data port可以达到更高波特率,我设计硬件电路时,能不能把电路改为The standard COM port is the application/user UART and the enhanced COM port is the data port.,谢谢
我用 UniFlash,通过CP2105(我用外置的USB转串模块,含CP2105芯片)的standard COM port连6843AOP(我自制的6843AOP板,留有串口)的user UART,不能烧写。但通过CP2105(我用外置的USB转串模块,含CP2105芯片)的enhanced COM port连6843AOP(我自制的6843AOP板,留有串口)的user UART,能烧写。我现在需要用standard COM por烧写,请指导。谢谢
因为按6843AOP EVM板原理图接法,DATA UART接受时好时坏,所以我才互换了串口,用enhanced COM port(可支持2M)接受数据,用standard COM por(最高支持921600)烧写。这样好处是接受数据稳定,坏处是不能烧写。你司的EVM板原理图违背常理的接法,可能也遇到这个问题,有好办法 吗
