Getting started with STM32F767ZI

Hi,

   I am just Getting started with STM32F767ZI using a Nucleo F767ZI dev board. Prior to that I have only used in commercial project PIC24H family of Microchip and embedded C language. Can anybody help with how to get started with it.Following are the question which are coming into my mind and struggling to find much online material .

1. How to add MCU specific header files. (Any libraries need to be added such SPL?)
2. How to use it without using HAL libraries.
3. Where to find example codes tutorial specific to above model.
4. Could not figure out how to just create not generic but MCU specific code just to blink an LED or control its inputs outputs.
5. Any other evaluation tools recommended for the above MCU to get started ?

Please Help.

To use at a register level without HAL you're going to have to digest the part's Reference Manual. The Low-Level (LL) libraries provide a thinner abstraction.

One can #include one of these depending on the level of abstraction you choose to work at

'stm32f7xx.h'

'stm32f7xx_hal.h'

'stm32f767xx.h'

The Cube source trees provide a large number of example projects, as well as templates for several leading IDE

STM32Cube_FW_F7_V1.11.0\Projects\STM32F767ZI-Nucleo\Examples\GPIO\GPIO_IOToggle\readme.txt

STM32Cube_FW_F7_V1.11.0\Projects\STM32F767ZI-Nucleo\Templates\readme.txt

STM32Cube_FW_F7_V1.11.0\Projects\STM32F767ZI-Nucleo\Templates_LL\readme.txt

You should review, build and test these before you step off on your own, that way you have a working reference to pivot from.

The choice of IDE tends to be a personal one, I find Keil to be relatively seamless in terms of being able to build, download and debug out of the box. It can also download support 'packs' that contain code/libraries separate from the whole Cube/HAL downloads.

Hi Clive One,

                   Thanks very much for you response. It is indeed helpful.

I am using IAR Embedded Workbench and not allowed to use Cube32 or Hall lib.

Do I need to load LL libraries or they are already provided in the IAR EWARM ?

Also, the examples you have mentioned they are from CUBE using a lot of Hal lib. 

Moreover, the header files you have recommended seem to be not build in as its quoted in '   ' which should be written by user rather than from libraries which is normally enclosed in <    >.

Please let me know about your thoughts

You're using IAR EWARM, not me, you'd be in a better position to know what it does and doesn't do or provide. ST provides EWARM templates/examples.

If you can't find include files it is because you haven't provided the correct 'Include Paths' to the compiler. The <> form works for stdio.h, stdlib.h and the like, the '' form is used by ST throughout there code.

>>Also, the examples you have mentioned they are from CUBE using a lot of Hal lib. 

The bulk of the code in the trees are handcrafted HAL examples, and the HAL libraries themselves, along with some middleware and board support code. ST provides this as a large monolithic download running 500MB-1GB downloads. You pull it all, you use/take what you need.

>>not allowed to use CubeMX or HAL lib.

Yeah, one of those, climb the learning curve with the materials provided, you can pivot to whatever free-climbing methods you're expected to use once you've figured which way is up.
