OLIMEXINO-STM32F3 and ADXL375 with SPI and micro sd write

[mgolbs]

Hello,
can I use a adafruit ADXL375 - High G Accelerometer (+-200g) with SPI and mircosd write on a OLIMEXINO-STM32F3 and witch port must I use, 3 ore 4 wire SPI?
 [CS, SDO, SDA and SCL]

Goal is, use the raw x, y and z acce with 100Hz sample, internal ADXL375 ADXL375_DATA_RATE_200. 24g are not enough in a drum. If SPI not possible, then must I use I2C.

SPI should be possible why not. You should use 4-wire SPI. If using the UEXT connector:

ADXL375 pin    UEXT pin    OLIMEXINO-STM32F3 signal
----------------------------------------------------
VIN            1           +3.3V
GND            2           GND
SDO            7           SPI1 MISO, D12 / PA6
SDA            8           SPI1 MOSI, D11 / PA7
SCL            9           SPI1 SCK,  D13 / PA5
CS             10          GPIO chip select, D4 / PB5

The onboard microSD uses SPI2 separately.

So the recommended setup is ADXL375 on UEXT/SPI1 and microSD on SPI2. Of course, some software effort will be needed.

Hello,
many thanks for the information an the listing of ports/pins!
