** ChibiOS/RT port for ARM-Cortex-M4 STM32F469. ** ** ChibiOS/HAL + ChibiOS/EX - I2C + PWM + ADXL317 demo for STM32F4xx. **

The demo runs on an ADI EVAL-SDP-CK1Z board. The demo runs on an ADI EVAL-SDP-CK1Z board. It has been tested
connecting an external the EVAL-ADXL317Z.
** The Demo ** ** The Demo **
The demo flashes the board LEDs using a thread, by short circuiting ARD-A0 The application demonstrates the use of the STM32F4xx I2C driver in order
to GND the test procedure is activated with output on the serial port SD5 to acquire data from ADXL317 using ChibiOS/EX.
(USART5, mapped on the CMSIS DAP Virtual COM Port).
** Board Setup **
With reference to the schematic of EVAL-ADXL317Z and
to the Schematic of the SDP-K1 the following connection
are needed:
---------------------------------------------
| EVAL-ADXL317Z | SDP-K1 |
|---------------------------------------------|
| | |
| P1.1 | ARD_GND |
| P1.5 | ARD_3 |
| P1.7 | ARD_D15 |
| P1.8 | ARD_D14 |
| P1.9 | ARD_3V3 |
---------------------------------------------
On the SDP-K1 move the Jumper P14 to 1.8V.
