Hi,

I'm trying to migrate an existing project from the Standard Peripheral Libraries to the new ones and can't fine any guides. Do any exist? As an example I'm currently trying to convert this function.

void I2C3_Configuration(void)
{
// I2C3, PA8, PC9
GPIO_InitTypeDef GPIO_InitStructure;
I2C_InitTypeDef I2C_InitStructure;

/* Configure GPIO pin alternate function */
GPIO_PinAFConfig(GPIOA, GPIO_PinSource8, GPIO_AF_I2C3);

Yeah, well you see the problem here is that Cube/HAL uses a completely different paradigm, you're going to have to rewrite everything. So the trick would be to learn how to use Cube/HAL, and then ponder how you can do what you had previously done with this new model.[DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Java/Any%20app%20note%20%20guide%20on%20migrating%20from%20STM32F2%20std.%20periph.%20lib.%20to%20HAL&FolderCTID=0x01200200770978C69A1141439FE559EB459D758000F9A0E3A95BA69146A17C2E80209ADC21&currentviews=279]https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=%2Fpublic%2FSTe2ecommunities%2Fmcu%2FLists%2FSTM32Java%2FAny%20app%20note%20%20guide%20on%20migrating%20from%20STM32F2%20std.%20periph.%20lib.%20to%20HAL&FolderCTID=0x01200200770978C69A1141439FE559EB459D758000F9A0E3A95BA69146A17C2E80209ADC21¤tviews=279

Thanks,

In that case is there any documentation that describes the old and new library structures in detail? For example it took be a while to work out __HAL_FREEZE_IWDG_DBGMCU() has replaced  DBGMCU_APB1PeriphConfig(DBGMCU_IWDG_STOP, ENABLE) Thanks, Gabriel
