Hi folks I am a newbie who has a great oppurtunity(relatively speaking) to make his first embedded design. I want to make an attenuator controller to control 32 digitaly programmable attenuators. I need 256 bit TTL compatible digital output (8/attenuator) . I am considering MCP23016 IC from microchip and pic microcontroller for this task. 8 MCP23016 ICs can be put on 1 IIC bus and i ...

I've just tried to order a Picstart Plus PUM from Microchip direct, 16.28 UKP for the board. After adding all the shipping and handling charges it's going to cost me 39.28 UKP. Does anyone know a way for me to get one of these in the UK without paying the ridiculous handling charges? -- Clint Sharp

Hi: I'm looking for DSP-like microcontrollers and microcontroller-like DSPs. So far I am interested in TMS320F2812, but it is a bit heavy handed for some applications I would be considering. I had decided to move away from Microchip a few years ago and instead standardize on AVR for my 8-bit MCU of choice, mainly because of avr-gcc and the AVR architecture is much more pleasant to w...

I have an Optrex LCD (DMC-20481NY-LY-AGE) that is 4x20 characters and driven by a Microchip PIC16F877 running at 20MHz. I know I got this exact same physical LCD to work before but for the life of me I can't recall what trick I used to do so. Attached at the end is my software. I get power to the LCD, but all I see is lines 1 and 3 as all dark and lines 2 and 4 as all clear. Hunting aroun...

Hello, Nowadays one often hears/readers about the transistor count of modern CPUs and GPUs. But what's the transistor count of common uCs like the Microchip PIC, Atmel AVR or similar microcontrollers? Just being curious :-) Thank you in advance! Regards, johannes

Hi, Although I have Googled TIMER1 info. on MicroChip devices, as a novice, I am somewhat confused and would appreciate a little help. I have a project I am developing where I wish to count the number of pulses from a 1 MHz square wave source. (I am measuring the time a light beam has been broken) Now, the 16 bits of Timer1 will allow me to count up to 65535 pulses, which at 1 MHz sh...

I am Ezekiel. I, and I am trying to download a program into the chip ( microchip pic18f4550) with window7 but could not be able to do it. One of the major problems, was that the system will be demanding for ICD2 USB driver in order to successfully carrid out. My question is Do anyone know how to downlaod an ICD2 USB Driver for window7 or Do anyone know the site i will visit to be able to ...

Hi - I have a system that consists of one Atmel SAM7X256 connected via CAN to 6 Microchip MCP2515 chips. The MCP2515s have 20MHz clocks, and the SAM7X256 has a 55MHz clock. I have the CAN bus running at 1MHz right now, but the chips aren't perfectly matched. Specifically, the SAM7X256 uses 11TQ, while the MCP2515 uses 10TQ. I had to do this as otherwise I'd have to have fractional baudrate di...

For production of measurement probes, we need to store calibration data on them. Because of the limited number of connections, the 1-wire memories look like good candidates. For now we need at least 16kbit of storage which should be eprom or eeprom. The only suitable device from maxim therefore seems to be the DS2505 with 16kbit eprom. (the larger ones are serialized 'uniqueware' devices). In...

pICSPeed is an in-circuit programmer for the PICmicro line of microcontrollers. It is made by In-Circuit Solutions from Canada. There is even a link to the company on the Microchip website. Don't buy from In-Circuit Solutions unless you want to limit yourself to the incomplete list of devices that their user interface supports, or you want to enjoy the frustration of dealing with extremely ...

I see a lot of commercially available solutions for adding a web server to an embedded application... however I dont see anything thats designed for a client type app. For example, my project has a LCD screen on it, and adding a network controller chip (realtek, microchip, etc) would not be a problem. What would be involved in retrieving and displaying web pages? Is there anything commerc...

I am looking for an PIC with three UART ports if such a thing exists. I have two UART inputs and I want to output a single UART output. I've seen plenty of ICs with 2 UART ports, but I have yet to find one with three. I typically use microchip ICs, but I am open to any brand as long as it would do the trick and has a good C compiler. How would a situation like this be handled in modern electro...

I have been searching high and low for the assembly language code to determine the log base two of a sixteen bit floating point number smaller than one. Has anybody had any luck? The AN660 from microchip is very complicated. The closest I came is the routine by Nikolai Golovchenko at piclist ( http://www.piclist.com/techref/postbot.asp?by=time&id=piclist/2000/09/28/080926a&tgt=&key=log2&f r

Does anybody know of a link to a Pickit 3 Users Guide, perhaps in PDF form? I was hoping to find one on the Microchip web site, but it seems to be obsessed with selling things. I'm trying to work out a strategy for prototyping with a host of PIC10Fs on host of tiny boards. I imagine it could get as bad as a bed-of-nails arrangement hooked to a programmer, but I can't find solid info. ...

Hello, I've got the picdem board, but was looking for other tcp/ip stack that run on the Pic18F452. I do not think the uClinux has been ported, but are there any source tcp/ip stacks that run on the Pic 18f Family, other than microchip? Sourcecode availability? I cannot find the sourcecode to microchips stck MCHPStack.2.11 either, only the executable. Any help is most appreciate...

Hello, Im trying to run the TCP/IP stack, that came with the TCP/IP lean book that i have recently bought, on the microchip PICDEM.net board. I have run the hex image that came on the CD with no problems, but i cant get version that i have compiled to work. It seems to just loop around with the display showing the P16Web v2.02 splash screen, the 'c' for my PCH compiler and 0.0.0.0 DHCP bei...
