STM32F4 timer interrupt help needed

[picclock]

Hi
I'm trying to implement a timer software interrupt. I've tried using the example from :
https://github.com/stm32duino/STM32Exam ... llback.ino
But this fails with:
STM32TimerInterrupt.h:67:5: error: 'TIM_TypeDef' does not name a type
TIM_TypeDef* _timer;

Could really use some help or pointers to information as I seem to be stuck ..

Best Regards

Use main source code, not from some branch:
https://github.com/stm32duino/STM32Exam ... llback.ino

If you still get compile errors, we need more information (IDE version, core version, your exact source code, etc.)

@GonzoG
The source code I am using is the official example per the link I quoted in my post.
Arduino Version is 1.8.15

If Board is selected as Blackpill : STM32F401CCU6
Error: 'TIM_TypeDef' does not name a type TIM_TypeDef* _timer;
or
If Board selected as Generic STM32F series, then Generic F401CCU6
Error : 'HardwareTimer::attachInterrupt(void (&)(HardwareTimer*))'

code from : https://github.com/stm32duino/STM32Exam ... llback.ino

Board from https://github.com/stm32duino/BoardMana ... raw/master package_stmicroelectronics_index.json

Programming with ST LINK V2, not that its relevant as the error is with compile.

Hope this clarifies things

The link you pasted is on the official github but it's not the main code, it's a branch and an old one (for core v1.8 or earlier)
The main code in under this address:
https:// github.com/stm32duino/STM32Examples/blob/main/examples/Peripherals/HardwareTimer/Timebase_callback/Timebase_callback.ino

Your link:
https:// github.com/stm32duino/STM32Examples/blob/824017c21d555001db1ce047d97b562c1b7b6a9c/examples/Peripherals/HardwareTimer/Timebase_callback/Timebase_callback.ino


The code from main code example compiles without any errors.

@ GonzoG
Thank You so much. I have spent hours trying to figure this out, getting nowhere.
Cunningly shortening the links so that they appear identical in the posts didn't help either .

Many Thanks for your assistance !!
