The code needed turned out to be simple:
//void pwm_start(PinName pin, uint32_t clock_freq, uint32_t period, uint32_t value, uint8_t do_init)
// set pwm frequency to 60.0 khz at 50% duty cycle on PA_6
pwm_start(PA_6, F_CPU, 1200, 600, 1);
//pinMode(PA6, PWM);
//void pwm_start(PinName pin, uint32_t clock_freq, uint32_t period, uint32_t value, uint8_t do_init)
// set pwm frequency to 60.0 khz at 50% duty cycle on PA_6
//void pwm_start(PA_6, F_CPU, 1200, 600, 1);
pwm_start(PA_6, F_CPU, 1200, 600, 1);
void setup()
{
pinMode(PA6, PWM);
}HardwareTimer pwmtimer(3);
setup() {
pinMode(PA6,PWM );
pwmtimer.pause();
pwmtimer.setPrescaleFactor(1);
pwmtimer.setOverflow(1200 - 1); // 72MHZ / 1200 = 60KHZ
pwmtimer.setCompare(TIMER_CH1, 600 - 1); // 50% duty cycle
pwmtimer.refresh();
pwmtimer.resume();
}Build options changed, rebuilding all

This looks like a mixture of windows path with linux path together …

I remember this board, but is not on the list now
even if i type only stm32
See https://github.com/stm32duino/Arduino_Core_STM32
Getting Started
This repo is available as a package usable with Arduino Boards Manager.
Use this link in the “Additional Boards Managers URLs” field:
https://github.com/stm32duino/BoardMana … index.json
I update from 1.4 to 1.5
No blue pill on the list – yet
Blue pill still not on the list and the new error confirmed that, what to do ?
Arduino: 1.8.8 (Windows Vista), Board: “Generic STM32F1 series, BluePill F103C6 (32K), STLink, Enabled (generic ‘Serial’), None, Low/Full Speed, Smallest (-Os default), Newlib Nano (default)”

The error ;

Is explained here
So install it from the board manager then it will install all required dependencies (tools, arm gcc and CMSIS).

Should I have here listed – blue pill ?
The menu section you posted is not STM’s core, it’s Roger’s.
I think you need to start afresh and follow the instructions linked by fpistm.
I suspect the folder ‘maple’ in your hardware folder is Roger’s – to save yourself confusion you should remove it.
This is what you should see from the official core:

An error occurred while uploading the sketch
On my fresh W10 install, I get an error about two missing DLLs. There are probably MSVC runtime files that need to be installed.
From Arduino, I see the same error message.

Thanks for your support, letter I will work on st link, I saw that some guys have a problem to make it working with W10

may be you have similar problem.
Your code allows to make the simplest program for 3 phase generator with 120 deg. shift using only one timer = unique
