radio decode ssb
Hello,
I started to play with SDR. I am building ZeroSDR receiver and thinking how SSB or CW demodulation works. I know I can use Rocky, M0KGK etc (anyway I need it for Linux as I do not have Windows OS).
I know that from I/Q signals I shift one of them for 90 degrees (and...
Finally I had a time to buidl the cable and test the connection. Unsuccessfully.
The problem is that Fisio 620 model needs hardware key inside the cable to enable modem in the phone.
Does somebody have a clue how this key works ? I can understand that it sends some ID to the phone. Can...
l9 meter wiring
I made LC-meter similar to AADE design but I have problem with stability.
I have big frequency swing like modulation or something similar.
Did somebody notice such behaviour ? I tried to change several components but it looks it did not help...
Can somebody help me ?
epm7096
Hello,
I got some old EPM7096LC84 devices.
I'd like to use them so I got Altera Maxplus software.
But don't know how to program them by myself. I don't have an access to any older programmer and new programmers don't support it. Unfortunately this Altera is without JTAG interface...
arm7tdmi debugger open source
Is there any source code for it ? We develop on one multi-core chip and have problems with OCDRemote. We currently develop some code by ourselves so maybe to reuse XJTAG can be better idea.
BTW: I see openjtag pages only in Chinese. Is there any english version ?
Re: How to measure 0-30V with ADC that has 5V maximum input
Are you sure that you don't have AN0 as output ? What is on output if you set "1" in your program ? Still 80mV ?

It looks really simple. Do you think I can control Fisio 620 through AT codes ? I tried to find some info but you are further than any web page I saw :-)
pic12f675 reset
OK, but you can't use common PIC but you need to buy "special edition" with on-chip ICD which has 14 pins, don't you?
Then it's same if you change a code little bit and use PIC16f873 with old ICD. Well, as I said, I plan to play with ICD...
Or can you emulate the P12F675...
pic12f675 debugg
In fact, I don't understand it too much. 12F675 does not contain On-Chip debugger silicon like 16F877 etc. I'm not using ICD up to now (anyway I want to try it).
My understanding was that during programming you should enable special configuration bit (bit11 in CONFIG register...
setting internal register 12f675 ccs
On this page:
**broken link removed**
it is written that ICD-S is only for PIC16F and PIC18F lines which support debug mode.
I haven't heard that P12F675 supports debug mode.
