** ChibiOS/HAL - SPI driver demo for ARM-Cortex-M3 ADUCM360. **
|

*****************************************************************************
|
||||
|
||||
** TARGET **
|
||||
|
||||
The demo can be compiled to run on multiple STM32 target boards.
|
||||
The demo runs on an ADICUP360 board.
|
||||
|
||||
** The Demo **
|
||||
|
||||
The application demonstrates the use of the HAL SPI driver.
|
||||
|
||||
** Board setup **
|
||||
|
||||
To redirect P0.1 and P0.2 to the SPI connector it is required to setup
|
||||
the switch matrix as:
|
||||
- S1 -> 0
|
||||
You should than connect P0.0 and P0.2 togheter (MISO1 and MOSI1 from the
|
||||
P7 connector): this would guarantee the loopback connection.
|
||||
|
||||
** Build Procedure **
|
||||
|
||||
The command "make" builds the demo for all targets. The demo can be compiled
|
