Data received on the primary serial port is relayed to the bus acting as an RS485 interface and vice versa. UART to RS485 translation hardware (e.g., MAX485, MAX33046E, ADM483) is assumed to be configured in half-duplex mode with collision detection as described inhttps://docs.espressif...

data: an array of data to send as bytes length: the number of bytes to transmit Returns byte: write() will return the number of bytes written, though reading that number is optional Example 举例 #include <Wire.h>byte val = 0;void setup(){ Wire.begin(); // join i2c bus }void...

This parameter is tricky and often causes wrong configurations. For historical reasons it is named PIN but it IS NOT A PIN NUMBER. It is the position in an array of analog input sources. In this array, the real pin number is stored. In 99.9% 0 is the correct answer here....
The Processing code reads the message as a string and uses the Javasplit()method to create an array from the comma-separated fields. Note In most cases, the first serial port will be the one you want when using a Mac and the last serial port will be the one you want when using Windo...
The "side" parameter must either be 0 or 1 The "sector" paramter must be in range 1..numSectors() The "buffer" parameter must be a pointer to a byte array of size (at least) 516 bytes. The function returns 0 if reading succeeded. Otherwise an error code is returned (seeTroubleshooti...
Gain-scheduled decay rate stabilisation (with 1 parameter) Eigen::MatrixXf**DecayRateGainScheduling1Param(Eigen::MatrixXf& A0, Eigen::MatrixXf& A1, Eigen::MatrixXf& B,floatamin,floatpmax,floatpmin); Returns a pointer to a two-dimensional array of MatriXf pointers object containing a matrixKo...
