If you use a microcontroller and a separate board with the SX126x transceiver you need to define the hwConfig structure to define the GPIO's used to connect the two chips. If you use the Insight SIP4520 or the RAKwireless RAK4630/4631 modules the connections between the chips are fixed. ...
If true, endTransmission() sends a stop message after transmission, releasing the I2C bus. If false, endTransmission() sends a restart message after transmission. The bus will not be released, which prevents another master device from transmitting between messages. This allows one master device to ...
function, the command 'Serial.parseInt' is used to read the number entered as text in the Serial Monitor and convert it into an 'int'. You can type any number here. The 'if' statement in the next line simply does an analog write with this number, if the number is between 0 and ...
bool set_gain(uint8_t gain = 128, bool forced = false)values: 128 (default), 64 or 32. If one uses an invalid value for the parameter gain, the channel and gain are not changed. If forced == false it will not set the new gain if the library "thinks" it already has the right...
if(mlx90640To[x] < lowPix) { // Colder pixel found? lowPix = mlx90640To[x]; // Likewise lowAddr = x; } } if(thermRange == 0) { // Are the colors set to auto-range? colorLow = lowPix; // Then high and low color values get updated ...
Everything between the two curly brackets or braces after 'void setup()' is the code that executes during the setup. Make sure you always close your brackets, otherwise, you'll get strange errors. The IDE helps you with this by highlighting the other bracket, if you select one. ...
(Ignored if using pre-1.5.7 Arduino software, which operates I2C at a fixed 100 KHz.) @return Adafruit_SSD1306 object. @note Call the object's begin() function before use -- buffer allocation is performed there! */ Adafruit_SSD1306(uint8_t w, uint8_t h, TwoWire *twi=&Wire, int...
The differences between these two will be covered in the section Duemilanove Versus Mini. If you’re already comfortable with electronics and wiring and you have a compelling reason, then you can easily apply the information in this chapter to one of the other Arduino controllers. Note that if...
