What is causing the fatal error: MCP4725.h in my Arduino code?

    Error
AI Thread Summary
The discussion centers on an issue encountered while uploading code to a Teensy board using Arduino, specifically an error indicating that the "MCP4725.h" file is missing. The error suggests that the code references the MCP4725 board, which requires the corresponding header file for proper compilation. To resolve this issue, it is necessary to either include the MCP4725.h file in the project or remove any code that depends on it. This solution addresses the compilation error and allows for successful uploading of the code to the Teensy board.

Dear all,

I am working on Arduino and try to upload to Teensy, but when I uploaded, I had a problem with this message,

"Interface22.ino:32:21: fatal error: MCP4725.h: No such file or directory
compilation terminated.
Error compiling"Could you please help for the reason and how to solve this problem?

Thank you very much,



Nate Duong.

Something in your program is referencing an MCP4725 board, and the MCP4725.h file describes its addresses, function, etc.

I don't know if there is an explicit include in your code, or whether it is being determined by the compiler. You need to add that file or eliminate the code that requires it.
 

Thread 'Learning Assembly and computer architecture for x86'

Dear Peeps I have posted a few questions about programing on this sectio of the PF forum. I want to ask you veterans how you folks learn program in assembly and about computer architecture for the x86 family. In addition to finish learning C, I am also reading the book From bits to Gates to C and Beyond. In the book, it uses the mini LC3 assembly language. I also have books on assembly programming and computer architecture. The few famous ones i have are Computer Organization and...

Thread 'Microsoft Technical Interview question'

I had a Microsoft Technical interview this past Friday, the question I was asked was this : How do you find the middle value for a dataset that is too big to fit in RAM? I was not able to figure this out during the interview, but I have been look in this all weekend and I read something online that said it can be done at O(N) using something called the counting sort histogram algorithm ( I did not learn that in my advanced data structures and algorithms class). I have watched some youtube...
