#189443 - It does not look like USB Responding to: ???'s previous message |

If he's trying to interface serial ports, ultimately via RF, it won't help him to interface to USB.
With the RS232 modules, he can use a cable to work out his signaling protocol, via cable, and then substitute the RF module, which he presumably has already verified for functionality, and proceed to implement his RF link in place of the cable. Don't you think that's betterand easier than involving a PC, especially with USB under Windows? RE It does not 'look' like USB, it looks like COMx, and you can use something really simple like FreeBasic to do this :
If Open Com ("com9:9665,n,8,1,cs100,ds0,bin" For Binary As #1) <> 0 Then 'cs100 senses DB9.Pin8
Print "Unable to open serial port" 'ds<>0 Reports if Pin 6 Not RDY
End
Else
Print #1 "U" ' Send AutoBaud char @ 9665 Baud
End If
Or, any Terminal can be fired up, and simple test strings sent. Users have to have a PC anyway, in order to Develop and Load their code ? The cheap CP2102 Module given in that link, can even PGM an AT89LP51RB2 in Boot mode. (connect RTS and DTR) |
