Arduino for STM32

For Win10, I use CMake + NMake.
Both work very well for generating Makefile and building embedded applications (AVR, ARM and now with RP2040).

I used ANT with linux a long time ago for J2ME applications.
I used Maven and currenlty use Gradle for building Android applications in Linux and Windows ...

Yes, there is an initialization function uint32_t DWT_Delay_Init(void) .
The whole code suggested is as follow:

dwt_stm32_delay.h
#ifndef DWT_STM32_DELAY_H
#define DWT_STM32_DELAY_H
#ifdef __cplusplus
extern 'C' {
#endif

#include 'stm32f4xx_hal.h'
/**
* @brief Initializes DWT_Cycle_Count for ...

I think that running the USB Host processing may take something close to 150us ... 150us in a 84MHz-100Mhz MCU means only 12,600-15,000 CPU cycles.

Using Timer/PWM IRQ may compete with USB Host processing, causing some issues for the data it gets or for USB Host timing.
That must be correctly ...

It shoud use HAL in Cube.

Try this, as it works with STM32F4, but not for the STM32F103:

const uint32_t cyclesPerMicroSecond = HAL_RCC_GetHCLKFreq() / 1000000;
uint32_t micros = DWT->CYCCNT / cyclesPerMicroSecond;


This code provides a delay in microseconds using HAL:


/**

To get the quadrature signal output to emulate the amiga mouse requires a 150us duration for each pulse, I've tried to implement this with a timer ...
Does anyone have any tips?


About the 150us duration, I understood that this is the minimum time necessary for Amiga to pick up changes on the ...

Very nice! A complete project with STL and documentation.
Thanks for sharing!!

Hi Victor,

One important step when intalling Roger's Core (STM32 Arduino based on LibMaple) is to install "Arduino Due Board" in order to setup the ARM Cortex M3 Tool Chain. By intalling the DUE, Arduino IDE will install necessary ARM compiler and others related to it.

This step is detailed in the ...

No... 100% real!

Well... now I got something cooler to show... :D :D

I've made my Pico emulate a NES and play Castlevania.
This game is very high CPU intensive and making it work in 60 FPS was a nice challenge.
High quality Sound/FX and smooth video graphics.

Pico dual Core at 250MHz => VGA 8bpp/256 colors + PDM ...

Is this Elite you're taking about?
