OK, found an RC-5 code on my remote, and immediately found my next problem :)
RC-5 sends 0 as 10, and 1 as 01. So 00 and 11 should not exist, right?
Even though I've pressed a key several times, I always get C1 to be 11, and either S2 or T to be 00.
Why is that?
You were right, the remote uses ITT protocol which doesn't use modulation.
Someone suggested that I should sample both TX and RX diodes, see picture.
Luckily, the remote is a universal one, so I'll look for a code that uses RC-5.
I've been playing with the TV remote control, capturing the data sent.
This is my second try, btw. Last time was two years ago, and now I'm failing at the same place...
As shown here, RC-5 remote repeats a code every 114ms.
That works, every 110ms I get something...
That something should be 14...
Hi all,
At first, I wanted to use '245 to convert 5V signals to 3V3, uni-directional, direction A to B.
Input signals may be floating, so I've added 10k pull ups to 5V on side A of '245.
Now I need it to be bi-directional, but I don't know if the 5V pull ups will harm the 3V3 outputs on side...
Say I have 3 nets: 5V, 5VA and 5VB.
I want to route 5VA and 5VB separately, then join them in some point(s) to 5V.
I've created a net class (CLASS5V) with all 3 nets so I can create a rule allowing
CLASS5V to be short-circuited to the same class.
That works great, I can route all 3 nets...
In Protel 98 I could place a part in sch using the keyboard
and specify the library reference (RES), component comment (1k) and footprint (0805)
I'm using IntegratedLibrary:PlaceLibraryComponent and all I can specify is library reference: LibReference=RES
How do I specify footprint and comment?
I'm using AT91SAM9260 (926ej-s) with PCK at 200MHz and MCK at 100MHz.
Every write to PIO ports (PIOA - PIOC) takes 50 ns, which is too long for me.
Is it possible to accelerate this port access using TCM (or anything else)?
Thanks
I've started programming AT91SAM9260 and some
things are not clear to me.
At first, sam-ba was giving me problems
(see https://embdev.net/topic/184418),
so I created a small win32 app to mimic sam-ba.
On reset, sam9260 sends "RomBOOT>" and then listens to commands.
I then issue some commands...
Hi everybody, I'm new to this forum!
Currently I'm using AT89C51 (plain) but need to
switch to the AT89C51RC2 for greater speed.
I've read the docs on RC2,
but some things aren't quite clear:
1. can the RC2 be programmed the same way (parallel)
as the AT89C51? If not, what should I change...
