Hi FvM
Thanks for the answer!
I can't use the 110V power supply (only 24VDC!!) otherwise the relay solution would be great!!!
So I have to try to find a solution to "convert" these 0/10V signals to 0/110V (the input currents are 100mA).
But at the moment I think that it is a little bit...
Hi all guys,
I have a "serious" problem with 2 interfaces..I explain better :).
I have an interface with 4 digital outputs that works with 0-10VDC level and I have another interface with 4 digital inputs that works with 0-110VDClevel.
My question is simple: is there some way to 11x amplify the...
Hi again,
I would extend my thread with another question that I hope somebody can answer :-)
I drawn this scheme (I know that it is not make enough sense :D):
The PIC2 has to control the 2way switches to decide which video signals have to connected to monitor. It has also used to switch...
Hi all,
I have an old arcade games with a CGA (Hsync 15kHz Vsync 60Hz) and EGA (Hsync 25kHz Vsync 60Hz) monitors and I want to interface with a PIC.
The arcade monitors, than a VGA monitors (Hsync 31kHz Vsync 60Hz), work with a different Hsync freq.
The video signals present on the monitor...
Hi all,
I want to build my first capacitive touch pic-project :) (I use the CCS C compiler, latest version).
I read a lot of pdfs downloaded from Microchip (in particular AN1250), I want to handle the capacitive touch slider.
At the page 13 of AN1250 microchip sheet, there are 4 equations.
In...
pvi-1004c lcd
Hi all,
sorry for my english.
I have 2 LCD screen 3.5" (rescue from 2 videotelephony) with the relative board interface (the controller is PVI-1004C, this is the datasheet: **broken link removed** ).
I want to know if it's possible to connect/interface this screen with a PIC or...
Hi all,
sorry for my english :)
I have an arcade 80/90's videogame cabinet :D with a Video CRT that works with a Horizontal Sync at 15Khz and Vertical Freq 60 Hz!
I want to connect it with my PC :-D but I know that the Horizontal Sync of my Video Card is a 31KHz.
Is it possible to convert/adapt...

Hi all,
sorry for my english :)
I have an old Ericsson T39 GSM phone and I want to re-use the display ;).
I have searched on the net some infos and I have found these:

Re: How to interface PIC with sst memory (JEDEC standard)
SD card has a different standard for to read\write\erase the memory :|
This is the datasheet of the memory that I want to interface with the PIC:

Hi all,
sorry for my english :D
I want to know if in internet there is a free project of 3D led display (images).
See this fantastic video on youtube:

The author haven't release the project :cry:
Thanks guys ;)
Bye.
Hi PiCS,
I have checked the connection many times :cry:.
Yep...I use the 16F877A version and I have tried 3 different MCU 4550 and 877A (I believed that it was a MCU problem :|)......none :(.
The problem is random.
Sometime the download OS progress freeze (the bar scroll infinitely).
Sometime...
Hi PiCS,
thanks for the answer :D
I have used for the PIC18F4550 the file 18F4550_bootFinal120807 downloaded from the user abrahamq....here the post:
Now I'm going to burn the firmware without the write protection (ICD2_18F4550_boot_Mclr_dis.hex)...but I think that will be the same thing...
