Unknown Clock
If I am willing to lose accuracy with the built in delay functions, is it absolutely critical to know the clock speed at compile time? I'm trying to write some software that will...

Tardy bus responses causing problems, odd behavior observed
I am using one of the UART interfaces on my ATMEGA128RFA1 to talk to an external device. The external device responds to all commands sent to it, but the response time varies (...

LwMeshTestamonial
Not to sound like too much of a homer, but in my opinion, LwMesh is great. I designed a board around the ATMEGA128RFA1, using the data sheet as a reference. I downloaded LwMesh,...

First variadic function...
After reading the text at: http://www.gnu.org/software/libc/manual/html_node/How-Variadic.html#How-Variadic, I wrote my first variadic function. It compiles, and appears to work...

Bizarre UART behavior
I have a board built around a ATMEGA128RFA1. One of the UARTs is translated by a MAX3250, and monitored by a PC. Because it is a 128RFA1, I have an external 16MHz crystal (fuses...

Header include order... Going crazy
I am creating a generic "library" (really just a .h/.c file pair) for interfacing to a particular chip. The library will be used in multiple applications. Each application will...

Array Size Allocation question
I would like to declare an array with a size determined by a [const] variable -- for readability purposes. This is the only place I am using this "variable", so a #define macro...

Build/Link Order Question
I am writing some code to interface with a specific chip. As such, I have created two standalone files (chip.h and chip.c) to provide a set of functions ("library", but not in...

Variable Arguments function
Is there a way to have a function accept a variable number of arguments, possibly none(emphasis on that last part)? When I try void foo(...) { } I get an error: "ISO C...

Re: Efficient way of building strings
I am writing a driver to interface with a 3rd party piece of hardware. The object responds to AT commands. Edit: compiler: AVRGCC (WinAvr) In a header file, I have defined a...

Low level LwMesh Questions
Warning: I am reading through each line of the LwMesh source code, to get a good understanding of what it is doing. I am going to have a number of questions (that may expose my...
