Do I need to write to the slave before I read or can I just read the value straight away? I've put part of my code below. Command Register #define TSL2561_ON 0x03 // Table 4. I have lots of examples on using the I2C bus on the website, but many of these are using high level controllers and do not show the detail of what is actually happening on the bus. MCP23008 8-bit I2C I/O expander (slave device), addressed in 7-bit mode, using interrupts. Using the example code in header files i wrote a similar function. I contacted tech support and they told me to use MCC for the configuration and to get libraries for it. In the mcc. The MCC is a Microchip GUI, provided with their IDE, that can be used to configure the various sections of the MCU, in particular here, the MSSP1. 10 and XC16 Compiler v1. If you use this code from MCC on a PICmicrocontroller, the function i2c_ISR must be duplicated due to the way the C stack is implemented on a PICmcu; If you want to save code space, simply decide how you want your code to run (interrupt or polled) and remove the call to i2c_isr from the master interrupt code or. Here is my thinking, first define the registers from the datasheet I want to access and the new pre-scaler (I want 50hz pwm for servos and not the default 200hz):. An10369 uart/spi/i2c code examples. This enables the bus and sets the baudrate at the same time with a comma separating both parameters. The devices don't have to be identical as long as they support I²C protocol. Follow the steps to open MPLAB Code Configurator (MCC) in MPLAB Xpress. I need help with I2C on a PIC16F1 device.

Also check out to have I2C-2 disabled on A9 if you use Wire, and I2C-4 disabled on A9 if you use Wire1. Finally, I ended up by using the provided I2C2. according to this, some slave devices need a REPEATED START, instead of a STOP+START, to be readable. Use the firmware update tool to update the firmware on your MCC 128 board(s). Create a new MPLAB X IDE project for PIC18F47Q10. 3 Configuring MSSP to I2C Mode. The I2C1 module is configured for Master mode, while I2C2 is configured as a slave. But foremost, I'd avoid MCC for I2C, in the short, medium and long term, it's an unnecessary complication, ironic considering MCC is meant to simplify things! The aim of MCC is clear, to take the chore of boilerplate configuration code away and leave the programmer to fill in the business logic. That address should be right-shifted one bit to form the address that the Arduino is going to use.
