Error: Identifier "RCC_APB2Periph_TIM9" is undefined in "main.cpp" with STM32 Discovery board F429I

Hi,

Im trying to get the following code here, (code pasted here)which was written to work on a very similar board, to work on the F429I Discovery board.

Ive started by bringing it into the mbed online compiler and adding the necessary libraries. #include "LCD_DISCO_F429ZI.h" and #include "mbed.h"

I am now trying to find the equivalent to the STM32F4 TIMER 9. (Of course this also goes for RCC_AHB1Periph_GPIOE, GPIO_Pin_5 | GPIO_Pin_6 etc. )

My question is, how do I go about figuring out how to 'port' this over to the F429I Disco. board? Im having a hard time finding out information about RCC_APB2Periph_TIM9 and what the equivalent would be.

I thought I would post this as I work through the datasheet, perhaps someone has a good suggestion

EDIT: So I've realized that the STM32 HAL API has replaced the legacy StdPeriph library. Is there anyway to use the StdPeriph libraries in the mbed online compiler?

many thanks in advance
