Arduino for STM32

final solution...

#include <HardwareTimer.h>

#define pin PA1
#define PinTimer(pin) (PIN_MAP[pin].timer_device->clk_id-RCC_TIMER1+1)
#define PinChannel(pin) (PIN_MAP[pin].timer_channel)

void setup() {
delay(1900);
Serial.print("Pin ");
Serial.print(pin);
Serial.print(" Timer ");
Serial.print ...

well I already solve my problem... Attachment with the library if anybody want to try it:

Hi
I made this sketch to sound a melody on a pin using a timer and an array of frequencies and periods...

HardwareTimer Timer(4);
uint8_t Pin = PB9;
bool Enabled;

long lastStart;
long Freq;
long lastFreq;
long lastConfig;
int lastCounter;
long Dura;
int counter;

uint32_t DutyCyc;
uint32_t ...

HI
I have these SSD1309 2.42 I2C OLED and it seems it is not compatible with the SSD1306 code available... did somebody knows how it can work ?

I just use stm32f103 series

So there is no way to obtain the timer number from a particular pin?

thanks from Costa Rica... I will try to move to that core...

thanks but I'm not using that core...
I use "Arduino_STM32-master" obtained here : https://github.com/rogerclarkmelbourne/Arduino_STM32

the code u send me does not work using that core.

HI

there is any way to obtain the timer number from the pin name on a STM32F103 generic board?
I mean using PA8 to obtain 1 as an integer (timer 1)...

I want to create a HardwareTimer object starting from the desired pin number, using TIMER = new HardwareTimer(TimNum);
so I need a way to obtain ...

@ rsonnicksen

when u do not want to use 2 bluepills in the same project because u need more timers, pins etc u need a bigger compatible bluepill ! (in the case u wanted in that way)

look for a STM32F103Z, "Z", or R, T V... they have more pins and/or memory and are 100% compatible with the normal ...
