STM32F469IDISCOVERY¶
lbuild config:modm:disco-f469ni:b-03
Discovery kit with STM32F469NI MCU.
This BSPsBoard::initialize() sets the board up with these settings:
- 180MHz CPU clock frequency in overdrive mode.
- 90MHz APB2 and 45MHz APB1 clock frequency.
- MODM_LOGGER initialized at 115.2kBaud outputting on STLink.
- 16MB SDRAM initialized for heap.
- Disables the display by default.
You can enable and use the on-board display in two ways:
- Use the
modm::GraphicDisplayreturned byBoard::getDisplay(), which initializes the display on first call and allocates the framebuffer in the external SDRAM. This is the simplest option. - Call
Board::initializeDisplay()and then provide your own display buffer withBoard::setDisplayBuffer(void*).
No Double-Buffering!
Double-buffering is not implemented, so you may notice some tearing if youupdate the display fast enough.
Access to the capacitive touchscreen is provided in theBoard::ft6 namespace.CallBoard::initializeTouchscreen() to setup the peripherals.
Hardware Revisions¶
The revision B-03 has a different touch sensor address from B-01 and B-02.The correct address for the revision is provided asBoard::ft6::TouchAddress:
Board::ft6::Touch::Datadata;Board::ft6::TouchtouchSensor(data,Board::ft6::TouchAddress);If you want to provide the same code for both revisions, you can change theaddress at runtime if the device does not respond to a ping:
if(nottouchSensor.ping())touchSensor.setAddress(Board::ft6::TouchAddress2);Default:b-03
Revisions:[b-01, b-02, b-03]
