I2CMasterBuffer = MAX30100_DEVICE | RD_BIT Īs you can see I've used some of the i2c.h lpcopen functions trying to adapt the arduino wire.h functions. Wire.beginTransmission(MAX30100_DEVICE) Uint8_t MAX30100::readRegister(uint8_t address) Wire.endTransmission() // end transmission Wire.write(val) // send value to write
Wire.write(address) // send register address Wire.beginTransmission(MAX30100_DEVICE) // start transmission to device Void MAX30100::writeRegister(byte address, byte val)
The main functions that use the I2C are the next ones: I forgot to say that I have made the same project in Arduino, so I'm trying to use the same program making some changings.
The lpcopen library is attached in this post. Well the question is that I don't know which things I have to pay attention and which not in the library, for example I know that I have to change the adress of the divice (which I know is 0xAE ) and some values for the externs (I2C Master and Slave Buffer, and read and write length) which will depend in the way that my device sends the data, but I dont know if I'm not considering something important. So I search for the datasheet of the LPC1769 and its seems that the pins that the I2C uses are the same, so i think I dont have to change anything from the I2C1Init function from i2c.c (I will just use the I2C1 pin 19 and 20).
Wire h library download how to#
So I'm trying to config the I2C of this divice with my LPC1769, I downloaded a lpcopen library from another question post that has an example of how to use the I2C in a LPC1768. This device is an optical sensor with an adc that transmit the data that it sense using I2C (and much more but this is the important part). I'm trying to make a pulsioximeter using a MAX30100.

Two Port Receive: Work with multiple software serial ports.Ĭorrections, suggestions, and new documentation should be posted to the Forum.because sometimes one serial port just isn't enough! Software Serial Example: Use this Library.Refer to the AltSoftSerial site for more information. AltSoftSerial overcomes a number of other issues with the core SoftwareSerial, but has it's own limitations. If your project requires simultaneous data flows, see Paul Stoffregen's AltSoftSerial library. On Arduino or Genuino 101 RX doesn't work on Pin 13.On Arduino or Genuino 101 the current maximum RX speed is 57600bps.Not all pins on the Leonardo and Micro support change interrupts, so only the following can be used for RX: 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).If using multiple software serial ports, only one can receive data at a time.The library has the following known limitations: The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart. A parameter enables inverted signaling for devices which require that protocol. It is possible to have multiple software serial ports with speeds up to 115200 bps. The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name " SoftwareSerial"). This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer. The native serial support happens via a piece of hardware (built into the chip) called a UART. The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). Reference Language | Libraries | Comparison | Changes
