It’s been a while since a board.h generator has not been announced :-)
I know the word probably does not need so many board.h generator, but I will nevertheless briefly expose the one that I use.
This one has be written to fulfil 2 goals :
1/ made easy frequent change in static configuration (teaching practical work)
2/ keep off graphical tool and reference manual
So, instead of generating board.h from STM32CubeMX description, it use as a source a dumb text format. It still need STM32CubeMX to be installed to use the xml description files of the MCU.
There is 2 modes of operation : board.h generation and query mode : to list alternate function and associated pins, associated dma streams and channels.
STM32CubeMX is a good tool to begin a new design, but when you want to change few pins during development, I feel it’s easier to just use a command line tool, and modify a text file.
I just show an example of pin description :
Code: Select all
PA04 VBAT_MEAS ADC ADC1_IN4
PA08 XB_ASSO INPUT FLOATING
PA09 USB_VBUS INPUT PULLDOWN
PA10 SD_DETECT INPUT PULLUP
PA11 OTG_FS_DM OTG AF:USB_OTG_FS_DM
PA12 OTG_FS_DP OTG AF:USB_OTG_FS_DP
PA15 SPI1_CS OUTPUT PUSHPULL SPEED_HIGH FLOATING LEVEL_HIGH
PB03 SPI1_SCK SPI AF:SPI1_SCK
PB04 SPI1_MISO SPI AF:SPI1_MISO
PB05 SPI1_MOSI SPI AF:SPI1_MOSI
PB06 USART1_TX UART AF:USART1_TX
PB07 USART1_RX UART AF:USART1_RX
PB08 I2C1_SCL I2C AF:I2C1_SCL
PB09 I2C1_SDA I2C AF:I2C1_SDA
PB10 I2C2_SCL I2C AF:I2C2_SCL
PB11 I2C2_SDA I2C AF:I2C2_SDA
PB12 LED1 LED
So, no need to open documentation to retrieve alternate function number, and the script check that the function can be attributed on the pin.
The tool is used in teaching class and by developers here at ENAC, so it will be maintained in the foreseeable future.
What can be painfull is the installation since it’ written in perl language : windows user will need to install a perl interpretor since there is no by default, linux and osx user are more lucky.
The full documentation is here :
script can be found there :
