Commit b4c1d92 not working with MemcardRex 1.8 #6

Closed xadox-1st closed 7 years ago

xadox-1st commented 7 years ago

After upgrading memcarduino from v2 to b4c1d92 I am not able to read or write memory cards anymore. Is the actual commit not compatible with MemcardRex 1.8?

ShendoXT commented 7 years ago

Communication protocol between PC and Arduino did not change so it's fully compatible with MemcardRex 1.8. However I did modify the acknowledge detection routine from the Memory Card itself by hooking an interrupt for faster reading instead of predetermined timeout values.

Make sure that Arduino pin 2 is correctly connected to the Memory Card. What card are you using, 1st or 3rd party?

xadox-1st commented 7 years ago

I tried an original sony one and a 3rd party one. With 0.2 only the 3rd party one was working. Never got the original one to work.

What version of the Arduino IDE should I use for flashing b4c1d92? Since 0.2 was only working with an older 1.0.5 IDE.

I added a testing branch where I introduced a compatible mode which should activate if ACK is not received. In theory that should make it work for you as it does on v0.2. I unfortunately don't have Arduino board with me so I can't test it but hopefully it will work. Post results.

You should always use the newest release of Arduino IDE. The reason v0.2 doesn't work is because of regression in IDE itself where functions with 2 byte arguments are not working properly. My workaround is to use a single uint variable to pass parameters.

Ok, I've just pulled out my arduino uno clone and tried using memcardrex 1.8 to read the latest commit version of the memcarduino project built in arduino ide 1.0.5-r2. it worked fine memcardrex reading card 1 so it may be that you have it wired wrong/ differently, what arduino are you using there, and how do you have your pinout setup in the code?

TheBlueTroll commented 7 years ago

and just for fun, i also rebuilt and uploaded from 1.6.13 arduino ide the same commit, and it also compiled and worked fine. the memory card in question is a official sony one, i have no third party ones that i could use anyway.

xadox-1st commented 7 years ago

@TheBlueTroll: I am using a nano clone. it is wired like shown on the picture on my post: https://github.com/ShendoXT/memcarduino/issues/6#issuecomment-263513209

I used the wiring by @ShendoXT: http://2.bp.blogspot.com/-jV7QoFBGHLg/Ucm9LsFZRzI/AAAAAAAAADo/7Brq8LHLKzQ/s1600/MemCARDuino.png

I connected both pins 3 and 5 to 5V on the nano. And I have not changed the pinout setup in the code. Do I have to?

I will try the new testing branch later today.

TheBlueTroll commented 7 years ago

Nope,you don't have to change the pinout, the spi port on the nano is the same as on the arduino, this worked for a third party card, but not a official? are you sure this card works in a ps1/ ps2 properly? the wiring looks fine. the nano is based upon the ATmega328, which is the same in the arduino uno, only in a smaller package. what exactly happens that makes you think that memcardrex now doesn't work? does it hang at the progress bar showing no progress, or does it error out detecting?

xadox-1st commented 7 years ago

The card is working fine on the ps1. Yes, it hang at the progress bar, right at the start. But I will try later again.

ShendoXT commented 7 years ago

I have found out that for some users it just won't work even if everything is set up properly. It could be the timing, logic levels (maybe that card won't work with 5V logic), or some to me unknown property messing with the communication. Without having the exact card to try there is not a lot I can do...

I'm curious however if the testing branch will work for you because it will fallback to method used in 0.2 if ACK is not received after first command.

xadox-1st commented 7 years ago

Yesterday I started from scratch. Installed a fresh Win7 with Arduino IDE 1.6.13. Uploaded memcarduino 0.4 from the testing branch.

Everything is working great now. Also my original sony memory card is working now. Tried reading, writing and formating.

I seems also to perform faster than on 0.2.

Thx for the update and support!

Edit: The original sony one looked like a original one, but after opening it turns out it is a 3rd party one. Someone has changed the pcb :(

ShendoXT commented 7 years ago

Awesome. I'm glad you got it working.
