Hi PoltoS,

attached the current state of the library together with the example sketch.

Best regards,
Andreas.

1. Don’t use things like
#define F(string_literal) (reinterpret_cast<const __FlashStringHelper *>(PSTR(string_literal)))
uCxx feels bad when It see this.

It doesn’t support C++-cast style.
Don’t worry about warnings about deprecated null-terminated string constants.

2. Don’t do this:

while (!Serial); // Do nothing if no serial port is opened (added for Arduinos based on ATMEGA32U4)

It’s a busy waiting. It works normally only on Atmels

3. Don’t use old-fashioned style of struct definition like:

Code: Select all

typedef struct {
		byte		keyByte[MF_KEY_SIZE];
} MIFARE_Key;

just use:

Code: Select all


struct MIFARE_Key {
		byte		keyByte[MF_KEY_SIZE];
};

uCxx will add «struct» keyword for all references to your struct MIFARE_Key automatically.

If you want to use old-fashioned typedef for structs:
use it like this (with defined struct name):

Code: Select all

typedef struct MIFARE_Key_s {
		byte		keyByte[MF_KEY_SIZE];
} MIFARE_Key;

4. Don't create constant vars inside headers.
uCxx makes no differences between const byte and byte and have no spetial constraints for constants.

So, uCxx will remove «const» modifier during build.

Just move

Code: Select all

byte MFRC522_firmware_referenceV0_0[64] = {
	0x00, 0x87, 0x98, 0x0f, 0x49, 0xFF, 0x07, 0x19,
	0xBF, 0x22, 0x30, 0x49, 0x59, 0x63, 0xAD, 0xCA,
	0x7F, 0xE3, 0x4E, 0x03, 0x5C, 0x4E, 0x49, 0x50,
	0x47, 0x9A, 0x37, 0x61, 0xE7, 0xE2, 0xC6, 0x2E,
	0x75, 0x5A, 0xED, 0x04, 0x3D, 0x02, 0x4B, 0x78,
	0x32, 0xFF, 0x58, 0x3B, 0x7C, 0xE9, 0x00, 0x94,
	0xB4, 0x4A, 0x59, 0x5B, 0xFD, 0xC9, 0x29, 0xDF,
	0x35, 0x96, 0x98, 0x9E, 0x4F, 0x30, 0x32, 0x8D
};

to .cpp file.

In header you can/(have to) add extern for this:

Code: Select all

extern byte MFRC522_firmware_referenceV0_0[64];

5. Don’t use enums as types.

You have to use byte/short/long (check MIN/MAX values of your enum) instead of it.

For Ex.

Code: Select all

	// <…>
	StatusCode status;
	status = getStatus();
	// <…>
	StatusCode getStatus()
	{
		return STATUS_OK;
	}

will be:

Code: Select all

	// <…>
	byte status;
	status = getStatus();
	// <…>
	byte getStatus()
	{
		return STATUS_OK;
	}

I applied all these rules to your files and library was compiled successful with my uCxx.
Some auxilary code was simplified a little.

All code attached here. Good luck.

Alex.

Hi p0lyg0n1,

wow! Thank you very much. I will check the code and see if the example sketch works. I will then check the other example sketches and modify them if needed.

Also the "style" guide tips are welcome, the might be interesting also for other users that want to adapt / port some code from the Arduino.

Again, thank you very much!
Andreas.

Hi,

strange, I can't compile your updated code without errors...

and the declaration is

Code: Select all

unsigned char MFRC522_firmware_referenceV0_0[64] = {0x00, 0x87, 0x98, 0x0f, 0x49, 0xFF, 0x07, 0x19, 0xBF, 0x22, 0x30, 0x49, 0x59, 0x63, 0xAD, 0xCA, 0x7F, 0xE3, 0x4E, 0x03, 0x5C, 0x4E, 0x49, 0x50, 0x47, 0x9A, 0x37, 0x61, 0xE7, 0xE2, 0xC6, 0x2E, 0x75, 0x5A, 0xED, 0x04, 0x3D, 0x02, 0x4B, 0x78, 0x32, 0xFF, 0x58, 0x3B, 0x7C, 0xE9, 0x00, 0x94, 0xB4, 0x4A, 0x59, 0x5B, 0xFD, 0xC9, 0x29, 0xDF, 0x35, 0x96, 0x98, 0x9E, 0x4F, 0x30, 0x32, 0x8D};
unsigned char MFRC522_firmware_referenceV1_0[64] = {0x00, 0xC6, 0x37, 0xD5, 0x32, 0xB7, 0x57, 0x5C, 0xC2, 0xD8, 0x7C, 0x4D, 0xD9, 0x70, 0xC7, 0x73, 0x10, 0xE6, 0xD2, 0xAA, 0x5E, 0xA1, 0x3E, 0x5A, 0x14, 0xAF, 0x30, 0x61, 0xC9, 0x70, 0xDB, 0x2E, 0x64, 0x22, 0x72, 0xB5, 0xBD, 0x65, 0xF4, 0xEC, 0x22, 0xBC, 0xD3, 0x72, 0x35, 0xCD, 0xAA, 0x41, 0x1F, 0xA7, 0xF3, 0x53, 0x14, 0xDE, 0x7E, 0x02, 0xD9, 0x0F, 0xB5, 0x5E, 0x25, 0x1D, 0x29, 0x79};

So the ucxx changed the defintion/declaration to unsigned char, but I can't see why there is an error message as it still is identical in the definiton/declaration.

I also get a lot of "strncpyz prevented buffer overrun!" messages that I can't understand as they do not point to anything.

There is also an error message where a byte is compared to an int8_t.

Why can you compile the code without error and I can't??
Are you using an updated version of the compilers > 2.0.6?

Regards,
Andreas.

Hi p0lyg0n1,

I just got the "small" library to run by reducing the stack size (thanks for all your help and all the tips for this topic).

But I also just found out that this "small" RFID library is in fact the base version for this larger MFRC522 library here, where you already helped a lot by changing the code so that it can compile.

I still have the problem that I got some compiler errors that apparently you did not have, but as there is only a very limited example sketch for this old/"small" library, I will not continue to work on that one but will instead continue to work on this larger library again.

First I will try to install the Arduino system on a linux server and see if the compiler behave different there. If you already used an updated version of the toolchain then I can only hope that the next update will be published soon

Regards,
Andreas.

Hi p0lyg0n1,

I have managed now to install the arduino IDE on a linux machine, but the compiler errors are the same than on my Windows 10 system...

So it seems I have to wait for the next version to fully compile it.

Best regards,
Andreas.

Hi p0lyg0n1,

I am a little bit further now...

When I remove the external definiton for the array in the header file I can compile the sketch! There are still a lot of warnings but it compiles!

I can read out a single register to see that my hardware is version 2, but the sketch crashes at the first larger function call. I expect that it is also due to excessice use of stack. But I guess that I can improve from this starting point by analyzing the *rst. At the moment there are single functions that use around 30 bytes of stack alone.

Best regards,
Andreas.

Hi, Andreas.

I am sorry... I read this forum not so often as I want. A lot of things around this project have to be done...
Errors with externs looks like a problems with previous version of compiler. I use alpha version of newest one and some problems we fixed in this version. So, you can use it too in one or two days too

Look for news.

Hi p0lyg0n1,

no need to apologize! You helped quite a lot.
Having an update for the compiler in a few days sounds good. I will not have soo many time in the next days but I will definitely install the update when it is published.
WIll check the "news" frequently!

Best regards,
Andreas.

Beta of 2.0.7 is there

You can try new compiler. It has some optimizations for stack usage...
