Arduino for STM32

Hello @cparata,

Ok, I will look into the Wire library implementation for Pico.

Have nice holidays!

Hello, cparata ,

(I have solved the other unrelated issue)

As you suggested, I tried adding a delay in the function NFCTAG_StatusTypeDef ST25DV_IO_Init(void) as shown here
NFCTAG_StatusTypeDef ST25DV_IO_Init(void)
{
if (st25dv._pwire == NULL) {
return NFCTAG_ERROR;
}

st25dv.ST25DV_GPO_Init ...

Hello,

I am using the WizFi360-EVB-Pico microcontroller (https://docs.wiznet.io/Product/Open-Source-Hardware/wizfi360-evb-pico/) which is based on a RP2040. Yes I connected 10KOhms pull-up resistors externally (from both I2C pins to VCC).

Actually, I have written another simple program to test the ...

Hello Carlo,

Thank you for your response.

Yes I have assigned arbitrary non connected pins of the microcontroller to variables GPO_PIN and LPD_PIN as shown in the Arduino code below :
#define SerialPort Serial

// Please define the pin and wire instance used for your board
#define GPO_PIN 1 ...

I am trying to program a Raspberry Pi Pico with Arduino in order to control the ST25DV NFC chip. I want to use the stm32duino ST25DV library.

I have a question about the pin assignment in the ST25DV_HelloWorld.ino program.

I am using the ST25DV 8-pins package and according to the datasheet there ...

Hi,

I'm corvo from France. I am trying to program a Raspberry Pi Pico with Arduino in order to control a ST25DV NFC chip.
