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 proje...

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 clock...

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 #define P...

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-options on...

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