Help moving someone else's code from MEGA2560 to Teensy 4.0

sremick · Apr 29, 2022

Code is located here: https://create.arduino.cc/projecthub/Sergey_Urusov/arduino-mega-chess-ii-b2e599

Display I'm using: https://www.ebay.com/itm/264583550286

MEGA2560 pin diagram: https://aws1.discourse-cdn.com/ardu.../368f6a73141b26b82227ae7794cc6920d402a618.png

So, I'm trying to migrate this code from the Mega to the Teensy. On the Mega it runs as-is with the display without any changes. just snap the display onto the Mega like it was designed, and everything just magically works "out of the box". Yay for that at least.

No so with the Teensy. The code compiles and uploads ok (There are "warnings" but no "errors" so I would hope it's ok?) I was able to map the pins 1-1:

LCD : MEGA : Teensy
--------------------------------
LCD_RD : A0 : 14
LCD_WR : A1 : 15
LCD_RS : A2 : 16
LCD_CS : A3 : 17
LCD_RST : A4 : 18
F_CS : A5 : 19
SD_SCK : 13 : 13
SD_D0 : 12 : 12
SD_DI : 11 : 11
SD_SS : 10 : 10
LCD_D1 : 9 : 9
LCD_D0 : 8 : 8
LCD_D7 : 7 : 7
LCD_D6 : 6 : 6
LCD_D5 : 5 : 5
LCD_D4 : 4 : 4
LCD_D3 : 3 : 3
LCD_D2 : 2 : 2

On the Teensy 4.0 pin diagram, pins 14-19 are also named A0-A5 so I was hoping it'd "just work".

I'm supplying the LCD's 3.3V from the Teensy's 3.3V out, and the LCD's 5V from the same source providing 5V to the Teensy VIN (it's actually like 4.77V).

Not sure what the problem is, but my first hunch is that even though the Teensy has the same pins, I might need to fiddle with pinmodes to get them to behave the way I want them too. Thing is, I'm not intimately familiar with the code or this display to even know which are input and which are output pins (it's a touchscreen, so some are output for that at least)

Second guess is a power issue...? Maybe 4.77V isn't close enough to 5V? Or maybe the Teensy's 250mA of 3.3V isn't enough? I would figure since the display has both 5V in and 3.3V in that the 5V is the primary power needing most the amps, and then the 3.3V is just as a digital reference...?

Too much of a newbie to know for sure, so I could use some guidance. Thanks!

Finally, the warnings I get when I compile for the Teensy (in case someone asks for it):

I was about to say post your code, but I see you have a pointer to it, but that is not the code that you are
trying to run because as you said you have modified it.
Please post the code you are trying to run.

I actually didn't modify it. When I said I was able to map the pins 1-1 that's not in the code, that's in my wiring/selection of pins on the Teensy to pins on the display. I've checked and re-checked my wiring and it matches what I put in the first post (whether that is actually "correct" is part of what I'm trying to determine). I used jumper wires so I can make changes easily.

Paste the code you are using.
If I had a problem I would not expect any helper to have to go to a third party site to see code.

(I see vBulletin adds scrollbars to the code blocks, so I guess it's not so bad)

Try running Teensy 4.1 at 24 MHz, in case the problem is as "simple" as Teensy running too fast.

Just use Tools > CPU Speed and upload again for the slow speed to take effect.

Well, today I learned how to set the Teensy speed.

Thanks.

I was really hoping it wasn't a speed issue as one reason I went with Teensy 4.0 was the performance boost over the Mega, but sure enough, setting the speed for 24MHz didn't result in any change.

It might be worth first just trying to write to the display.
There does not seem to much information about writing to the display with 8bit parallel interface.
Have a look at this.

Help moving someone else's code from MEGA2560 to Teensy 4.0
