ATtiny26 has ports on in reset
How about a hardware fix, add a resistor between the port and the FET gate, then connect a diode from the reset line to the gate, so that when the reset line is low the FET is...

c language "->" commando
It is a way of accessing a member of a structure when using a pointer to that structure, maybe some C guru can give you a better explanation, or maybe you should look it up in any...

I can't make my chip work with this code
I'll enlighten you. Stack shouldn't be needed since there are no calls. Branches and jumps don't save a return address,so as long as there are no interrupts enabled, the code...

First attempt to use GCC - make file problem
Yes, I think you need to define the device. It should be in the makefile. Maybe you should post your makefile (you'll need to rename it first I think).

#include ignored in assembler file
Dear me, It seems that you have to explicilty enable the C pre-processor with the -x assembler-with-cpp option (I might have missed a hyphen there). I don't quite understand why,...

Source Code ('C' or ASM) for CLIP
I have a bunch of other PDFs relating to Caller ID spec and chips. However, I don't really want to attach them all, it might be considered bad form on this forum. Maybe somebody...

PORTx DDRx settings visa versa
Most microcontroller I/O pins default to being inputs at reset, and are consequently high impedance. There is a good reason for this; it's contention proof, i.e. it avoids damage...

LANC control for SONY camera
I'd be fairly suprised if the camera did any collision detection as well, but I wouldn't rule it out. The LANC interface _can_ support more than one slave device connected to one...

LANC control for SONY camera
The most important thing you must do is to signal with the DDR bit. It's quite possible that the camera performs some sort or "collision" checking, and if your device is...

LANC control for SONY camera
A couple of microseconds either way probably won't make much difference. It all depends on how the camera samples the bits you send, it may just sample once in the centre of the...

LANC control for SONY camera
Just looked at your schematic, I see you already have a pullup resistor.
