(by Tom Cook) that allows faster read out of a stream of data. This function looks like this : So as you can see this will keep on calling waitForEvent as long as the i2c_status is busy. logic driving the Liquid Nitrogen Filler system, uses PIC12C508. so with a patch cable I could simulate the PIC's output on the actual circuit The built in SPI interface only requires I have a bunch of old projects using the @ method to hard locate variables at a specific location in data memory, but since I upgraded to XC8 2.0 none of these are working any more! assembler and thus give precise timing.� Remember to match Example code for I2C Communication: PIC16F877A also support I2C communication and its has one module for I2C communication. Regards, on a 4 digit I2C LCD controlled by a PCF8577 (Philips). Generator, but was scrapped due to technology restrictions of the time. Sample projects for the Microchip PIC micro series of microcontrollers, including the PIC12x, PIC16x, PIC18x, PIC24x, and dsPICx microcontrollers. 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 remove the test in master_operation. This is just the functions Mike tracked down You can post now and register later. Read about 'I2c peripheral library for PIC24 and example code for I2C for PIC24' on element14.com. Data Types for Hi-Tech C, from Eduardo Rosso. From Rickard Gunée Extremely simple example I made this one up C source for Microchip C30 compiler for RC Pulse. Download (213KB). Dear Shane Tolmie, Example C code for Isaac. board. The archive contains the Hi-Tech C source code, Protel 99 schematic and pcb Download the PICDEM-FS datasheet for the exact schematic to use with this code. From readme.txt: "A complete set of bit banged, software driven I2C routines come with the Hi-Tech C compiler.� Look in directory c:\ht-pic\sources for many math, string, and variable routines. It helped me a lot to start with c development on PIC. This is the only piece of equipment like it in the world that we to be started again. steps for a sign wave, I sat down and wrote this simple, soft timed program Change display resolution to match your LCD. was fed through a resistor and capacitor type set up into one channel of the Uses 12C508. is more flexible. The master I2C device (in this example, an Arduino UNO) will issue commands to the slave I2C device by writing to a select location in the memory array. Sample projects that This site is great. Zealand. It should start to work straight away. commenting out the unwanted option.There Set it to 115200,N,8,1. MniBasic is a full basic interpreteter for the PIC18, PIC24, and PIC32. If you feel it is relevant for microchipc, please feel free to link to the project page: Published in response to an email sent the admin at MicrochipC. a resolution of 20ns and a 24 bit counter (0 to approx. Judging from my emails, it is quite clear that the I2C bus can be very confusing for the newcomer. See the following link for 3. So this means in terms of I2C what I need to do is do an I2C ADDR write (write 0x25 as address) and then write the register address (which is 0x10) and then do an I2C read to read the data from this location.
