Used Peripheral Modules
|
||
|
|
=======================
|
||
|
|
|
||
|
|
This section lists all the used peripheral modules of the ``STM32F407VxT6``.
|
||
|
|
|
||
|
|
Core Peripherals
|
||
|
|
----------------
|
||
|
|
|
||
|
|
- ``SysTick``: Generating a 100us tick for the LCD routine and 1ms base system tick.
|
||
|
|
- ``NVIC``: Interrupt controller
|
||
|
|
- ``FPU``: The Flaoting Point Unit is activated and used in this formware.
|
||
|
|
|
||
|
|
AHB Peripherals
|
||
|
|
---------------
|
||
|
|
|
||
|
|
- ``DMA2``
|
||
|
|
- ``Stream0``: DMA transfer of PT1000 measurement ADC to memory
|
||
|
|
- ``Stream4``: DMA transfer of Safety ADC measurement values
|
||
|
|
- ``Stream5``: Shell UART RX
|
||
|
|
- ``Stream7``: Shell UART TX
|
||
|
|
