i think diagram will be like this

oh i forgot to mention that i read HidDemo.lua, com.write or com.writefeature function was not used in that file.

Hello Pete, Under of thanks for your response. Did you mean com port (COM1, COM2)? My expectation was that it will work like luahidapi library that im using right now that fulfills my requirements. but i want to use default com.write or com.writefeature function of fsuipc to write hid buffer. Ofcourse Arduino reads and writes to com port.. but i need to write to HID buffer. I read somewhere that HID is better than serial communication.

Hello Pete, Sorry for late reply, my internet was not working...now i'm online...Pete i'm using custom pic18f4550 joystick board. I want to get airspeed value into that chip or board by hid buffer using the mikroc code in previous post, mikroc is an IDE to write program for embedded system. i edited lua script according to you. now i got it that get and set are sessions variable. now problem is the edited code is not working according to my need.. and also im confused how does com.write function work?

Thanks Thomas..I'll update then reply you :)

hello Thomas I'm using FSUIPC4.937

oh my mistake I did not set dev and wrf...I changed the code according to you Thomas, but it's not working...I'm confused that can I receive values that will be written by com.writefeature, into microcontroller? I'm using fsuipc ver 4.9 I'm glad for your response thankq very much

thanks Volker for your response

i read that post but pete mentioned Thomas.

why no one answering my post :-(

hello everyone, I made a program in mikroc compiler that reads hid buffer values and write that values to the 7 segment display. I copied below ipcready.lua file into fsx modules folder, that file writes air speed values to hid buffer. but com.writefeature is not working i think. Vendor = 0x1234 Product = 0x0001 Device = 0 Report = 0 dev, rd, wrf, wr, init = com.openhid(Vendor, Product, Device, Report) if dev == 0 then ipc.log("Could not open HID") ipc.exit() end -- Finish HID Connect function call_speed (offset, value) com.write(dev,tostring(value), wr) end event.offset (0x07E2, "UW", "call_speed") -- aircraft speed In mikroc program im reading buffer and put values into 7 segment display like below: while(1) { if(HID_Read() != 0) { AsciiToChar(&readbuff); SevenSegmentPrint(ss,(int)atoi(readbuff)); } SetADCInputToUSBBuffer(); } can anyone help how can i resolve the issue?

hello everyone, I'm calling com.writefeature(dev, "123",wrf) with event offset of air speed. my mikroc code is if(HID_Read() != 0) { AsciiToChar(&readbuff); } but hid read is not reading string from com.writefeature. i dont know why? help me please. thanks in advance

Hello Peter How do i write hid buffer in lua script?...My problem is I want to get AP altitude value then write that value into HID buffer using lua. HID buffer will update 7 segment display by pic microconroller. thanks
