Plug ft232 on the computer, I use a wire to RX and tX sub, send out the problem; If I use CH340 is no problem, what reason is this?

CodePudding user response:

Using a serial port assistant software testing and have a look

CodePudding user response:

Haven't met, but the ft232 rate is still good

Try to lower the baud rate, it is possible that the hardware circuit to produce a little error

CodePudding user response:

Don't know the building Lord solve: no, I encountered a similar problem: I use CH340 chip serial port and the next bit machine communication is normal, but with the FT232 serial port, baud rate must be transferred to the 1200 it to normal communication, but I must set the baud rate equipment real-time demand for more than 115200, but this data will be lost, and I put the FT232 serial port to send and receive pin nipple, use serial debugging assistant can normal send and receive data no problem, that line is no problem, drive also is normal, is this why?
