With help, excuse me, vb6.0 by use of 51 single-chip microcomputer system hardware connection need what? Like what cable, urgent urgent!

CodePudding user response:

Serial or parallel

CodePudding user response:

It should be a serial port, via a serial port cable to connect the PC and single chip microcomputer,

CodePudding user response:

MSCOMM control,

CodePudding user response:

Hardware can be via a serial port, parallel port or usb etc.
Software need mscomm control above, or the corresponding usb control

CodePudding user response:

Is usually a serial port or UART usb, rs232 or rs485

CodePudding user response:

What to see whether the single chip microcomputer interface, and MCU application code USES what kind of interface,

Common are:

* a serial port, generally need to add RS232 chip to convert the level, because the PC serial port using + 15 v.
* USB port, the microcontroller is also depends on what kind of device class, common have HID, MSD, CCID and CDC (one of the subclass is U turn string);
* SPI mouth, this need to PC parallel port (print) was used to simulate SPI hosts,

CodePudding user response:

Use a serial port, convenient, stable, simple,
