fxMouse - Control your pc with casio fx9860

If that doesn't happen when you don't do Comm_Open, then the answer is probably yes.

[SimonLothar]

Comm_Open(0x20);

This establishs the basic link between USB host (PC) and USB device (calculator). Now the USB host has to enumerate the USB devices to find the correct device name and open a communication channel with CreateFile.

I can't find Comm_TransmitOneByte in the documentation - what are the syscall adresses?

If you look for "syscalls, fx-9860" in the index, you'll reach the legacy syscall table. Comm_TransmitOneByte is call 0x0291. Most of the Comm-functions should work like the corresponding serial functions. The corresponding serial function should be 0x040E: "int Serial_BufferedTransmitOneByte( unsigned char byte_to_transmit );" (USB is always buffered).

I wrote an add-in

Slightly OT, but Helder: Is the calc-calc cable that comes in the package a little loose? Mine keeps coming off when plugged in.

Also, have you tried Flourish? Doesn't work for me like shown in the video (I made calc1 1, calc2 2, and pressed 0 on calc1. Balls move in calc1 but there is no change in calc2)

Then the contact spring of the socket needs retension. The cable usually is OK.

Yes, I have tested with:
fx9860gii sd <-> fx9860gii sd
fx9860gii sd <-> fx-cg20
fx-cg20 <-> fx-cg20
It worked in every situation (with balls). Sometimes the chat does not work well with many messages.
Maybe your problem is with the cable.

================================================

I think that the usb version of the add-in is ok.
How i can read the data sent by calculator in pc?
Is there any way to create a virtual COM port, using the data sent by the calculator via usb?

To get the correct filename for CreateFile, you need the following functions of SetupApi.dll:
function SetupDiGetClassDevs;
function SetupDiDestroyDeviceInfoList;
function SetupDiEnumDeviceInterfaces;
function SetupDiGetDeviceInterfaceDetail;

I implemented the GetDeviceName-function in Pascal.
I could post the source, if you want to have it.

[helder7]

This appears to be a bit tricky for me. I never worked with Pascal for exemple.
I will not continue to try to create a usb version of the add-in, sorry. Currently the version 3 pin serves my needs.
I'll put my effort in another (more important) casio project I'm working.

I am trying to connect two FX9860GII's together using a cable that I took from the box of a brand new FX9860GII-2. Could that be the problem?

I think the cables are the same. Maybe you have to press stronger when you plug the cable in.

Pressed hard until it wouldn't go in any further. It's loose for both calcs. May be the cable is the issue. Waiting for my 3pin to serial cable to arrive to test again.
