Are these things just utterly useless? It would appear* that the USB handling in MPLAB-X is poorly tested. Might be that "grab reset on the DUT" is the problem. *can't really tell which end of the cable is at fault - although the "IDT" grabs it nine out of ten falls. There is even an app note not to use the PICKit3 "for production". An ICD3 works just fine. -- Les Cargill

The TI MSP430 looks like an interesting chip. The low power operation allows 16 bit adc onchip. Now they seem to be doing the sort of things that microchip did in the past such as free seminars and low cost development tools. Like most companies, we have a lot of software written for other microcontrollers, but we will certainly look at TI for new designs. www.ti.com/ez430

Does anyone out there know about a decent c compiler which targets the pic18 family? So far, I played with the Sourceboost C compiler and the Microchip C18 compiler, I'm happy with none of these, am willing to spend some money on something really good, but won't waste my time on buying and trying... -- Grinnikend door het leven...

Ok, flamewar time I guess. I am looking to explore new microcontrollers because the ones I have under my belt are coming up short for what I need. I have a lot of experience with the 16 series of PICs from Microchip, I have played with basic Stamps (I, II, SX), some experience with Motorola's HC11, HC12 and HC16 series. Currently I use Atmel's AVR (Atmega128) at work. But in trying to b...

Not sure how I missed this one for two months. I see there is already some serious contention with Atmel employees. http://www.eetimes.com/document.asp?doc_id=1329412 I wonder what it will be like for the sales force to be selling PICs, AVRs and ARMs all into much of the same market space? I wonder if the PIC32 will finally bite the dust with ARMs all around it crowding it out of t...

Hi, I'm so interested in Operating Systems and Embedded Systems. I have basic knowledge about both of them. But I want to go deeper. I asked before same questions. But the answer was not enough. Let's start from beginning. I have made some experiment on Microchip's PIC like light LEDs. Which Microcontroller is the most used or which is good to start? My target(or dream) is to port linu...

Hi, I have been developing an application using a Microchip 18F452 with 40 Mhz clock. Unfortunately, it seems like the device is too slow for the application and I need something faster. Hence I am asking for some recommendations. My application is the following. The processor is connected to an analog sensor. It needs to sample the sensor to a 10-bit digital value and transmit it bit-b...

[or the day I looked into the face of Hell. :-)] And now for something a little different. :-) What experiences have you had during debugging an embedded system that make you really wonder out loud what the hell was going on ? I've been building a homebrew programmer for the PIC32MX and have hit some major issues due to the really lousy Microchip programming specification. At one po...

It would appear I am about to start on a project using dsPIC30F6015 programmed in C using Microchip's toolchain. It's a long time since I did any PIC work (and taht was a smaller PIC)and don't seem to have an favourites or news groups that are relevant. I am sure there are some pitfalls to avoid and tips for making life easier (and software better). Where might I find them, or help wit...

What do you really use for embedded projects? Do you use "standard" makefile or do you rely on IDE functionalities? Nowadays every MCU manufacturers give IDE, mostly for free, usually based on Eclipse (Atmel Studio and Microchip are probably the most important exception). Anyway most of them use arm gcc as the compiler. I usually try to compile the same project for the embedded target...

Greetings all, I have a PIC project, and I am new to PICs. I need to set up a development environment as cheaply as possible. Can anyone direct me to inexpensive (or free) development tools for a PIC 16F; I found nothing at GNU, and Microchip's site had me running around in circles. At this point, all that I need is an IDE (or compiler/linker) and in-system programmer, but might decide ...

Hi all, I've been experimenting with receiver circuits and I'm missing something. The LC receiver I have (one of Ming's) and the Microchip (433.92 MHz, rfRXD0420) seem to have noise at the output when they're not receiving a signal. I see the signal (on a scope) when I press a button in the respectively transmitter. But if I have this signal apply to the input of a micro, it looks lik...

I am looking for a microcontroller with the attributes listed below. It is for a network interface that will be interfacing with only one digital or analog I/O. It is desirable use a battery for powering the device. It will be sending the value of the I/O along with a date/time stamp. A few microchip solutions have been listed below, but I would be interested it there is a better solution...

Hi, Is the 2051 capable of generating DTMF like what is described in AN655 of the microchip Apnotes? If not, can someone recommend a cheap and easily available chip that would be interfaced to the 2051? I know I can get the DTMF dialer chip from a used telephone set but it is normally for connecting to a numeric keypad instead of the data lines of the cpu. Thanks and regards. Alle...

Hi @ll Microchip offers his new controllers (i.e. dsPIC) with > 40 leads only in the TQFP but not PLCC package. Sockets for TQFP are not reliable. Thus they are no solution. What does that mean? The original PCB cannot longer be used for developement, because sockets are not possible. You have to design a special PCB for that. The only way I found, is to solder the device under tes
microcontrollers supported for critical systems

Can someone suggest a simple microcontroller that doesn't carry the "not for use in life support systems as a critical component" disclaimer? Having an Ada compiler would be a big plus. This is going to be a watchdog for computer components of a medical monitor, so it doesn't need to be very powerful but it does need to be reliable. We've been prototyping using Microchip PICs, and I was ...

I would like to build my own programmer for Microchip PICs. There are many schematics on the Internet available but I can't seem to find exactly what I want. What I would like is something that provides all (or most) of the following functions: * Can program PIC18 family of devices (or all of the major PIC families if possible) * In-circuit programming (not debugging): the electronics us...
