hello i use the nucleo 64 from STM with the micro STM32F103RB
SO if i do a simple program the blink led, it work.
but when i try program to use the TFT i have a error
and the error apear when i put/call:
include // Core graphics library
include // Hardware-specific library for ST7735
if is build to board = genericSTM32F103RB no have problems
and importante is in the "menu" on left side in platformio.ini
i have this
[env:genericSTM32F407VET6]
platform = ststm32
board = genericSTM32F407VET6
framework = arduino
upload_protocol = stlink
monitor_speed = 115200
; nao resolveu build_flags = -lc
board_build.mcu = stm32f407vet6
and the errorrrrrr
