3 compile errors in the example sketch HardwareTimerPWMInput.in

[mrguen]

Hello,

I am looking for a way to use TIMER INPUT and found this nice example sketch " HardwareTimerPWMInput.in" but there are a few compilation errors:

1. Streaming.h: No such file or directory

Then after removing this include:

HardwareTimerPWMInput:28:9: error: no match for 'operator<<' (operand types are 'USBSerial' and 'const char [80]')

Serial << "Example of the Timer Input Capture mode to measure PWM pulse width and period\n\n";

HardwareTimerPWMInput:73:61: error: 'endl' was not declared in this scope

Serial << ", period: " << Timer2.getCompare(TIMER_CH1) << endl;

Configuration:
Win 7 64 pro
Arduino IDE 1.8.9
Arduino_Core_STM32 1.5.0 updated via boards manager

Hi @mrguen
This is normal as this example is not for this core. It is for this one:
https://github.com/rogerclarkmelbourne/Arduino_STM32
which is different.

@fpistm Ok, there is still something that I don't get: why the rest of the code compiles? For example I thought there was no support for TIMER INPUT in Arduino_Core_STM32 (couldn't find this defines in the core) but this code compiles with TIMER_IC_INPUT_DEFAULT and it uses the predefined timer instances...

Also: is it possible to use all timers configuration (INPUT CAPTURE etc) within Arduino_Core_STM32 ?

[fpistm]

TIMER_IC_INPUT_DEFAULT is not defined in this core.
This core uses the CMSIS definition and STM32 HAL/LL from STMicrolectronics.
You can see #473 (an example is available in #447).
To use it you need to use the GitHub repository as I do not yet release it yet.
Furthermore an HardwareTimer library will be provide later to handle more easily Timer features (#146)

[fpistm]

Maybe, but I could not tell you why.
You use a sketch which is not for this core so I could not help you on this.
As it seems you use also @rogerclarkmelbourne core, use this example with this core.

Ok, I was confused because the boards manager shows "STM32F1Boards (STM32duino.com)" so I thought It was refering to an Arduino_Core_STM32 board. In fact I am using Roger Clark Melbourne libraries. Thanks for the fast answer.

Welcome.
So you should open an issue here:
https://github.com/rogerclarkmelbourne/Arduino_STM32/issues

Close this one as OP open rogerclarkmelbourne/Arduino_STM32#626
