Reading device or board specific properties from the Arduino MKR WiFi 1010 device

[semyuelshekh]

does anyone know how to read programmatically the device specific properties from the Arduino MKR WiFi 1010 chip or board?

For example, following properties of the device:

• any identification number, that can uniquely identify the physical device, integer or GUID or string or any other, how to read that from the code?
• SerialNumber of the MRK WiFi 1010 device
• ModelNumber of the MRK WiFi 1010 device

I have tried to check the documentation and examples, however I couldn't find anything at all. Please, help.

I dont have a MKR WiFi 1010, but the following works for all the boards I have, so I think it should apply.

In the IDE click on "Tools", and then "Get Board Info".
A box should then pop up with the board name, its VID, PID and Serial Number.

The following screenshots are from IDE 2.2.0, but other versions work similarly.

@JohnLincoln thanks for the example. I need exaclty that, however read from the code, programmatically. Any idea how that can be done in code?

the SN is build this way

uint8_t Serial_::getShortName(char* name) {
	// from section 9.3.3 of the datasheet
	#define SERIAL_NUMBER_WORD_0	*(volatile uint32_t*)(0x0080A00C)
	#define SERIAL_NUMBER_WORD_1	*(volatile uint32_t*)(0x0080A040)
	#define SERIAL_NUMBER_WORD_2	*(volatile uint32_t*)(0x0080A044)
	#define SERIAL_NUMBER_WORD_3	*(volatile uint32_t*)(0x0080A048)

	utox8(SERIAL_NUMBER_WORD_0, &name[0]);
	utox8(SERIAL_NUMBER_WORD_1, &name[8]);
	utox8(SERIAL_NUMBER_WORD_2, &name[16]);
	utox8(SERIAL_NUMBER_WORD_3, &name[24]);
	return 32;
}

@Juraj are you trying to help? that's something very bizzare. What do you mean the Serial Number is built? I was thinking that it is stored in the board constant memory?

[Juraj]

what the IDE shows a SN is composed by that function.
that code reads the register of the MCU where the serial number is stored.
