Posted on July 11, 2018 at 10:44Dear Kavana shree,
I, like most people, am quite new to this micro controller too.
What helped me so far:
1. Get a Nucleo board, very cheap with attached ST-link, it has a STM32H743 on it, it is missing crypto/hash processor of the STM32H753 but has the same peripherals.
2. ST has bought TrueStudio, you can use that for free.
3. Use STM32CubeMx to generate a code skeleton (HAL drivers) and that you can open in TrueStudio.
4. Reference the

5. Reference the
https://www.st.com/content/st_com/en/support/resources/resource-selector.html?querycriteria=productId=LN2033$$resourceCategory=technical_literature$$resourceType=programming_manual
6. Download
https://www.st.com/en/embedded-software/stm32cubeh7.html
it contains examples that you can run on the Nucleo board
7. Google
Good luck!
Martin
