Arduino for STM32

ok i will continoue on github, thanks.

thanks for your reply, after i change the setting (use crystal/ceramic resonator), my code is working.
but its just working when i use gpio and usb only, but i need other peripheral also.

i also try to make new project with only usb and gpio enabled, its working, but after i change to my other ...

hey all,

recently i started new project (STM32F407VGT6) use USB FS with stm32 CUBE IDE, i choose clock source from bypass(cause usb cant use internal clock), after code is generated by cube ide, i check by blink led on PA1, but the led is not blinking at all. but after i disable USB and change ...

thanks for reply.
even though the definition is above exactly, thank you for the help

// UART Definitions
#ifndef SERIAL_UART_INSTANCE
#define SERIAL_UART_INSTANCE 4 //<<<<<<<<<<<<<<<<<<
#endif

// Default pin used for generic 'Serial' instance
// Mandatory for Firmata
#ifndef PIN_SERIAL_RX ...

i don't know if this question already answered, but.

when i try to doing serial communication(STM32F407VGTx) in default Serial instance i need to set

Serial.setRx(PA10);
Serial.setTx(PA9);


even i already change default pin on variant_generic.h (i use generic board), and i have use --board ...

i got it, iam newbie sorry for stupid question.
thanks

recently i started learn stm32f407vgt6 with arduino core, then i want to try make my own variant, i have read this on manual https://github.com/stm32duino/wiki/wiki/Add-a-new-variant-%28board%29 , but on generated variant files section, i don't know how to generate this file, then.
based from this ...
