Hi Joe!!
I got it!!!
I've made a little VB6 program able to write characters to FIC Spectra Futaba display!!
I've retrieved the handle of the file corresponding with this HID device PID(
0x7000) and VID(
0x0547), it is a composite USB device so it has three instances, I've selected the one with 65 output buffer lenght (that is the first one returned by a FindTheHid function) and then once opened with API
CreateFile I've send a buffer with
WriteFile
the buffer is composed by 0x00 0x8B 0x04 0x01 0x07 xx xx xx xx xx xx xx 0x00 0x00 0x00... (filled with 00s the 65 byte buffer) where xx are the ascii codes of the characters to display...the display only supports uppercase and numbers
attached is the VB6 code...is just a first try to get it to work but enought to display characters...I'll try also to lit the different icons of the display but I don't know if this will be possible to implement with the MP internal structure
i.e. will it be possible to lit the REC icon when a recording is in place? or TV GUIDE icon or VOLUME bar according to MP master volume control?
