Hello, I am looking at doing some fast ADC conversions and notice that the data sheets specify that CHold is not discharged between samples. So if I leave it on the same channel does that mean that the Tacq is much lower? It would depend on how much CHold droops during the conversion. Does anyone know the details of this? I am looking at doing this on a PIC16F877 and also a dsPIC30F3013...


PIC USART and Transmission on serial port

Hi all, I am using 16 bit PIC18F2420 microcontroller with a single USART port. I am using MPLAB C18 compiler. I was trying to achieve duplex communication on a microcontroller with a single usart. I am using external interrupts for that purpose. All was well until now. The main problem is that when I send a string or array of characters to the pic, the computer on the other corner receives e...

I've been searching around for examples, but learning is slow going. At the moment I'm trying to program a 16f628a to light one LED for a controlled length of time and then light another for a controlled length of time and then the program should end. This is just a learning exercise. I'm using the HiTech C compiler with MPLAB and programming with a PICkit2. When I run the code that I've...

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...

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 ...

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 ...
