Pad printf for the MSP4.The output function printf translates internal values to characters.This simple definition comes from the book C Programming Language by Kernighan and Ritchie.I highly recommend this book to anyone who is interested in learning more about C, it is a must have for any embedded programmer.The printf function will allow us to display any value in your code so that it is human readable.What does this mean Lets say you would like to tell the computer what temperature your MSP4.Temperature 7. 1F.We know how to read the internal temperature from a previous post, but how do we get our MSP4.Thanks for the great post, although Im a little confused how to use Realterm to communicate with the MSP430 over UART.I have my MSP430 launchpad hooked up to my.My Rottweiler would have ate the face off a bugler and had an excellent temperament.They are territorial but in 10 years never had a problem and only growled and.PIC16F84 12 or 24 Hour Digital Clock Circuit Diagram And Programming This PIC digital clock is based on a 16F84 microcontroller.AUvk9ey7jPTVVDQp_foA-CVqduop9rhHBnt7uX748IeTloMrp8WzPp0ayAGSm52P0=h900' alt='Little Alarm Clock 06 10 2012' title='Little Alarm Clock 06 10 2012' />UART We use the printf function.Temperature uFrn, temp.Value. I will not be explaining how printf actually works in this post.If you would like more information on how to use this function please see the above mentioned book, or this link.Due to the fact that the MSP4.Since the printf included in Code Composed Studio is very large and will not fit on many of the value line MSP4.Possum on the 4. 3oh.Possums code. This is a tiny printf function that can be used with the chips that come with the Launchpad.Code size is about 6.CCS. This is how o.Possum describes his function.While this function does not support all of the standard printf features, it is more than sufficient for use on an MSP4.Using this function, we can format 7 separate data types character, string, integer, unsigned integer, long, unsigned long, and hexadecimal 1.I want to thank o.Possum for sharing his code with the community.The code is very well written and works greatThanks again Code.Please scroll down for the rest of the post.One of these days I will figure out how to limit the height of my embedded code.Customizing the Output.Depending on your project, you will want to have printf output differently.For this example, printf will send the formatted string out over the UART to a computer.For a different project, you might want to output the string to an LCD, or through USB.The code provided from o.Possum allows you to define two functions, puts and putc which determines how printf will output the formatted string.Without defining these two functions, the printf will actually not do a thing.In the code above, my.UART using another of my functions, send.Byteunsigned char.The code in these functions is fairly straight forward, and will not be discussed here.If you would like to another output for printf, you would create your own putschar and putcunsigned functions as I have done in the code above.Testing the printf Function.I will be using a very similar setup as o. Blue Screen Irql_Not_Less_Or_Equal Windows 7 Installation on this page. Possum for testing the printf function.The code above will send a test sequence to the computer when the MSP4.UART. I recommend using Realterm for interfacing with the MSP4.UART. To connect, select the correct COM port and set the baud rate to 9.Once connected, send the character t by clicking on the blank window and typing t.You should see the following response from the MSP4.Conclusion. Use this code in your projectsIt really is a great piece of code.To use this printf function to your own CCS projects, just add printf.I have done in this example.In the next post, I will expand on the previous post by creating a real time clock using the MSP4.
