STM32 (Bluepill) with i2c bme280

Sample code stm32duino upload via stlink

#include <Wire.h>
#include <SPI.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

Adafruit_BME280 bme;

void setup() 
{
    Serial.begin(115200);
    bme.begin(0x76); //i2c address must declare,or try i2c scanner first
}
void loop() 
{
    Serial.print("Temperat: ");   
    Serial.println(bme.readTemperature(),1);
    Serial.print("Humidity: ");
    Serial.println(bme.readHumidity(),1);
    Serial.print("Pressure: ");     
    Serial.println((bme.readPressure()/100),1);              
    delay(1000);

STM32 Bluepill dan Arduino IDE di Ubuntu

Kali ini saya akan sharing mengenai cara menggunakan arduino IDE di STM32 Bluepill ok langsung saja begini caranya.

1. Pastikan sudah memiliki stm32 bluepill
2. Pastikan sudah menginstall arduino IDE
3. Masuk ke board manager lalu install Arduino SAM Boards (32 bit ARM Cortex M3)
4. Download library disini lalu unzip kemudian copykan foldernya ke dalam hardware di Arduino IDE
5. Karena kita menggunakan ubuntu sebagai OS maka kita harus menginstall beberapa library yang sudah disediakan, caranya masuk ke hardware lalu ke Arduino_STM32 yang tadi kita masukkan lalu ke tools dan kemudian ke folder linux setelah itu klik kanan lalu klik open in terminal.
6. Setelah terminal terbuka lalu ketikkan ./install.sh kemudian tinggal diikuti saja perintahnya dan selesai .
7. Agar kita bisa upload via usb maka kita perlu memflash stm32 bluepill menggunakan firmware maple mini
