Hi, I've got an application where an existing RTD interface circuitry needs upgrading, and I'm looking for a custom chip that will handle the current sourcing and amplification necessary. The current circuit is composed of op amps, resistors and caps, and I would think there would be a single chip solution for this, possibly one that might also have a built-in ADC of 12 bits or more, and have a...


Anyone want a USBProg PIC programmer cheap?

This is a great PIC programmer (http://www.embedinc.com/products/usbprog/index.htm) and served me well for about a year and a half, but then it stopped working. Olin Lathrop of Embed assures me that from the diagnostics that the problem can be easily located. He didn't say that it could be easily fixed but I guess that was implied. However, I needed a replacement right away so I bought another ...

Hii.. EveryBody I have a strange problem.... I have wrote a simple code void main() {       TRISB = 0 ;       PORTB = 0 ;       DELAY_MS( 2000 ) ;       PORTB = 255 ;       DELAY_MS( 2000);       while(1)       {           PORTB = 0xF0 ;       } } So everytime O/p Of PORTB will 0XF0. Only when a reset will occur all the L...


I2C vs SPI

Hi. Just been looking at I/O Expanders from Microchip, and you can get them in either I2C or SPI. The only differences i can see are SPI can go faster, and I2C uses less pins. Is that about it? Thanks, Paul ------------------------------------

Hello, My initial searches have produced little information and if someone here could point me in the right direction it would be great. I am building a smart battery charger. The interface is constructed from a PIC16F877A, a 16x2 parallel LCD display, and 4 switch inputs. I am using Hi-Tech PICC for a compiler. And yes, I know C will produce large code and ASM would be better but I just ...

Recognizing serial ports in Linux/WINE/MPLAB

My OS is Puppy Linux. I'm running MPLAB through WINE instead of Windows. My programmer is a PICSTART Plus. I'm using a USB-serial converter to connect the PICSTART Plus to a USB port on my laptop, which lacks real serial ports. I can figure out the port my PICSTART Plus (with the USB-serial cable) is attached to by typing "dmesg|grep tty" in a shell window. (It's ttyUSB0.) THE PROBLE...


CCS C (older version 3.245) & PIC16F887

My CCS C compiler (PCM) is old enough to not have a 16f887.h include file but I was wanting to try that chip. I emailed CCS tech support asking if they had a 16f887.h but they said "You will need a version 4 compiler to use the 887 chip." I find that hard to believe if, in fact, the PIC16F887 is a true PIC16F family part with classic PIC16F peripherals. So I have that question in to...
