Thanks for you attention and help! :)
All operations I made in MIOS Studio 2.1
Update to new mios was be correct – for Pic 18F4685 via midi.
Once again, step by step:
1. I connect my VFD display Futaba M202SD16AJ via 4bit ( http://ucapps.de/mbh..._4bit_mios8.pdf ) to Core with Pic 18F4685 with mios v1_9d. After power on display show me “READY.â€
2. I load the last sid v2 firmware - V2.0_rc37, display show me how formatted my memory chips and after that I can see MidiBox Sid V2 interface on my display, I load patches and test the sound of my 6581.
3. I update mios to v1_9g, and after that I got a blank display (I see nothing) after this update.
4. I load again last sid v2 firmware - V2.0_rc37, display still blank (I see nothing), but my 6581 sound ok!
5. Post this topic.
6. Reset id to all zero via change_id app, load mios v1_9g, load last sid v2 firmware - V2.0_rc37, display still blank (I see nothing), but my 6581 sound ok!
7. I double check connection via lcd_interconnection_test_v2.zip, and check again data shit for my display and found one error… Pin 3 must be not connected, but I connect them to the V0 Pin on Core.
8. I load again last sid v2 firmware - V2.0_rc37, display still blank (I see nothing), but my 6581 sound ok!
9. I check another LCD display, it works fine!!!
I kill my VFD via mios update, because I forgot disconnect Pin 3?
I can’t understand what’s going on. =(((
