Noise in ADC
I'm in the process of bringing up a prototype and have the same problem. The ADC reading are jumping all over the place. If I take 16 readings and average them it gets a bit...

0603 vs 0805
I'm in the process of assembling and testing my first SMD prototype. I've gone with 0603 because, from what I read, there is not much difference in difficulty between 0804 and...

Adding ASF to my own project & makefile
For now I've given up on ASF. The ST7565R part does not seem to provide fonts for character output anyway and my homegrown routines do work enough to prove that the hardware of...

Adding ASF to my own project & makefile
I do only include the definitions I need. In my source code I have this: #include "conf_st7565r.h" #include and in my makefile this INCLUDES = -I /usr/local/asf-3.3.0 -I /...
