Help interfacing a multiplex VFD display
This bit of assembly code (written for GCC) will loop up an ASCII character in a font array that consists of five bytes that hold the 35-bits of the character. The MSB of the...

Help interfacing a multiplex VFD display
Funny, I was working on this two weeks ago and just fired up AVR Studio to have another crack at it! I was having trouble displaying much at all but I was able to get some garbled...

FatFs vs uALFAT
You can fopen, fclose, fprintf, and fscanf with FatFS. Definitely not just "BIOS" level commands. In fact, those low-level sector writing commands are left to the user to write....

Read a SPI register
You can also use bitmasks to see which bits are set and, if they are, set the corresponding pin. See which one takes up less space!

How much has a debugger (almost emulator) helped you?
The mk II has been a great purchase for me. I don't want to go back to the days of toggling LEDs and working up a bit-banged UART for debug printf statements. Of course, I was...

Picking a Hakko soldering station
I ended up ordering the FX-951. Nobody gets yelled at for spending a bit more on often-used equipment! I tried it out the other day and it was fantastic! It came to heat in 10...

Question regarding the "brains" of microcontroller
ECE 270 is a class at Purdue University that deals with all of this quite well. Luckily for you all of the annotated Powerpoint presentations are presented online along with video...

A projekt (novis)
Why not use 7-segment displays? They are very readable and simple to interface with. You can even get big ones that are sure to be visible from quite a distance. Does it need to...
