Reverse Engineering Ford 5000 RDS Radio LCD

-

it's mid sized display 8 cool alpha chars, numeric digits , custom glyphs

it's featured on lot of models of ford stock radios different glyphs , setups, i'ts i2c controlled , works @ 5v interfacing arduino piece of cake :)

some models can be:::
4050 rds
4500
4600 cdr
5000 rds
5000 rds eon (that's 1 had... super common unit)
6000 cd rds
6000 mp3
7000 rds

those not rare , considering people replace em cd\mp3 units there may lot lying around

control chip apparently pca8576d there's datasheet online (that it's surface-stuck on glass careful when handling, lcd has header don't need desolder it, careful pins)

after i2c valid-address scan found response, googled , voilà 8) (of course analyzed circuit before) made sketch lighting 1 pixel @ time know matrix arrangement

there "cool" power amplifiers on radio, marked "70039ab" instead tda8566 (currently using 1 of em on mini amp)
....and multiple voltage regulator isn't fancy anyways it's marked "70530fb" it's instead tda3609

i'm posting different sketches:::
one digit scanner (with button?... don't remember, time has passed)
one script visualizer via serial monitor (just write , display it)
the other 1 dumb clock , script visualizer (it may need "i2c master library")

there jpgs pixel map (other radios may have different "glasses" (or controllers))

sorry coding :smiley-small:

Flip address is out of range arduino uno r3

-
hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino Uno not uploading

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

-
i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
