In MCC you select the peripherals you want to work with using an intuitive GUI - then you click generate code and all the skeleton code is generated for you.

This will cause the File Registers window to appear. Path. An example how to use the I2C MCC read and write functions. MCC: Add MSSP peripheral for I2C bus.

The I2C1 module is configured for Master mode, while I2C2 is configured as a slave. Do I need to write to the slave before I read or can I just read the … The data received back from the Slave is stored in the RXArray[PACKET_SIZE] data array, which begins at address 0100, and ends at address 017F. The ADCC was configured to perform 32 burst average conversions and then right shift them by 5 (divide by 32). Additionally, a jumper wire (orange wire) was used to connect the UART TX pin (RB7) of the PIC18F16Q40 to the TX connection on the Curiosity LPC Virtual COM port for serial communication.

If you do not accept our terms and conditions and policies, please do not use MPLAB Xpress or its offerings. I have 2 problems with this method. Note: Resistors R55 and R53 must be removed from the back of the Curiosity LPC development board to disconnect the SPI SCK and MISO signals from the existing pins and re-route them to the pins described below. I used MCC to specify internal oscillator 1MHz and used the MSSP Peripherals to specify that it's an I2C Master. In the article below, an example of how to read temperature from an I 2 C Temperature sensor with MPLAB XC8 Compiler using MPLAB Code Configurator (MCC) is explained. I've used the MCC to set up I2C and I have I2C.c and I2C.h. Learn the basics of I2C communication with PIC microcontroller. will this code work with the 18F45K22? PIC18F16Q40 curiosity weather station code example. Learn more. Using the debugger allows the user to halt the program and check the file registers to ensure accurate communication. The compensation routines used to convert the BME280 raw outputs to temperature in degrees Celsius, atmospheric pressure in inches of mercury, and relative humidity as a percentage are shown below. The code to do this looks rather long, but it is not complex. This code example can be ported directly into the main file to quickly test the functionality of the device in I didn't use the i2c_utils, but went straight to the MCC-generated examples. These …
call the function to send a byte out, poll the interrupts for a I2C byte received.
