Arduino for STM32

I tried your sketch. It gave same output. Is there any possibility of a problem in library? And you properly wire the sensor on pin D9, D11,D12 and D13 ? If the SPI loop works so probably an issue with the Library. Maybe SPI clock speed. Seems the max frequency for this sensor is 8MHz as stated her...

_ File/Examples/SRM32duino_Examples/NoNReg/SPI_Loop

It can pass the test. There is no problem.

Did it pass test when connected to D14/D15 ??

Nope it passed D12 D11

Ok you use the STM32 core anyway your sketch is not correct. Try the code I've put above. I tried your sketch. It gave same output. Is there any possibility of a problem in library?

So you set this in your sketch and wire on the correct pins ? // You can also use software SPI and define your own pins! #define BMP183_CLK 13 #define BMP183_SDO 12 // AKA MISO #define BMP183_SDI 11 // AKA MOSI // You'll also need a chip-select pin, use any pin! #define BMP183_CS 9 // initialize wi...

SPI uses MOSI/MISO pins: D10 and D11.

I tried it, it gives same output.

Nothing change, it gives same output.

I don't see image. Could you share your sketch and how you wire the BMP to the board. #include <f401reMap.h> #include <SPI.h> #include <Adafruit_Sensor.h> #include <Adafruit_BMP183.h> // For hardware SPI: // Connect SCK to SPI Clock, SDO to SPI MISO, and SDI to SPI MOSI // See http://arduino.cc/en/...
