Artemis Arduino Core • Re: How do I make the GNSS Arduino library work with a stm32 board?

Quite a few... To port an Arduino library to work with the STM32 Nucleo-H7A3ZI-Q board using CubeIDE, you need to make the following key changes:

1. Replace Arduino-specific libraries with their STM32 HAL equivalents:
- Replace `Wire.h` with `stm32h7xx_hal_i2c.h` for I2C
- Replace `SPI.h` with `stm32h7xx_hal_spi.h` for SPI
- Replace `Serial.h` with `stm32h7xx_hal_uart.h` for UART

2. Modify the library code to use STM32 HAL APIs instead of Arduino APIs. For example:
- `digitalWrite()` becomes `HAL_GPIO_WritePin()`
- `analogRead()` becomes `HAL_ADC_GetValue()`
- `delay()` becomes `HAL_Delay()`

3. Configure the required peripherals (UART, I2C, SPI, etc.) in CubeIDE and initialize them in your code using the corresponding `MX_<Peripheral>_Init()` functions generated by CubeIDE

4. Ensure the library's timing and delay functions are compatible with the STM32 HAL by either:
- Replacing them with `HAL_Delay()` or a timer-based delay function.
- Adapting the existing delay functions to use a timer peripheral

5. Adjust any pin mappings or configurations specific to the Arduino board to match the STM32 Nucleo-H7A3ZI-Q board's pinout and peripheral mappings

6. Build and link the modified library with your CubeIDE project, ensuring any required STM32 HAL libraries are also linked

The process can be time-consuming, as you may need to refactor significant portions of the library code to work with the STM32 HAL APIs and peripherals. Thoroughly testing the ported library is also crucial to ensure proper functionality
