STM32L4 ISR source

Hi,

Is there any doc mention about STM32L4 (STM32L4996 and STM32L4A6) ISR source? The doc I found from both ST and ARM reference manual do seems list all of the ISR source.

Thanks,

Hard to decipher

See pg 396 of RM0351 Rev 6, Table 57 'Vector Table'

The 'position' field indicates the ISR managed by the NVIC

Hi Clive,

Got it. Thanks.

Is there any .h file already define all of those ISR number?

Thanks,

Dick

STM32Cube_FW_L4_V1.11.0\Drivers\CMSIS\Device\ST\STM32L4xx\Include\stm32l4a6xx.h

Via

STM32Cube_FW_L4_V1.11.0\Drivers\CMSIS\Device\ST\STM32L4xx\Include\stm32l4xx.h

and define STM32L4A6xx on compiler command line

Hi,

Is there any example code to manipulate ISR such as trigger, set pripority,

on/off...etc?

Thanks,

Dick

Open the project in the IDE (Keil or whatever you have). Build the project.

Then right click on the identifier and select 'go to definition'.

The demo projects should build without any errors. Unless you open the project in a wrong IDE or there's some problem with installation of the IDE.

Might I suggest you review Joseph Yiu's Essential Cortex-M3/M4 book and chapters related to NVIC. Settings for Group Priority, and Preemption being of particular importance.

Please review also the assorted HAL examples provided under the repository trees. Use a 'File Manager' to search and view file content.

Yes, I am reading the HAL user's manual. I saw those functions you

mentioned in the email.

One more question - is there any functions to set/get M4 register value?

Thanks,

Dick

Which registers specifically?

Many peripheral and NVIC registers are mapped into memory so are accessible using normal read/write variables, or pointers.

The processor registers (ie R0..R15) would be better accessed via assembler code or inlined as they are nominally used for parameter passing to/from C functions and to hold intermediate values in computations.
