Outside of the hobbyist ecosystem, what is the actual market size for new, non-legacy, ICs with a maximum Vcc of ~5V ? I've just picked up a few of the new Microchip 1Mbit SPI RAM ICs: http://uk.farnell.com/microchip/23lcv1024-i-p/sram-serial-1mbit-2-5-5-5v-8pdip/dp/2291921 and I was utterly amazed to see them available in this 5V capable packaging. This is a product range which until...

Hi, I would like to select a Floating Point DSP. I was looking-up the Microchip website and I see things like: "Support for Floating Point" and "Floating Point Library" I get a feeling as if they only have a software workaround and not a true Floating Point hardware implementation. Somehow their wording about Floating Point DSPs does not sound like that of TI or ADI. It ...

Hey all, I'm new to microcontrollers and I need to program my microchip PIC18F2321 to communicate via I2C with a processor so I can turn the radio's power on or off or set a specific frequency for the radio to operate on. I read microchip's sample code for programming master mode as well as the AN734 doc. I'm still confused as to what to do. I've never done any hardware programming before o...

I'm using Microchip's PicKit serial analyzer to find out why my I2C is playing up. The analyzer is set up to be an I2C slave and to accept external power. However, when I start communication then the PC software crashes and the Just-In-Time debugging reports a System.NullReferenceException error. I've downloaded the latest version of the software, updated the firmware in the analyzer ...

I need protocol stacks for Android, including ADB, MSD, BEE, etc. Says Linux? It's too big and no native support for BEE (ZigBee). Says Atmel or Microchip? I've worked with both USB stacks. They are both very similar: inefficient and deficient. I wonder who copy whom. I've been porting and rewriting the microchip USB host stack. I came to the conclusion that it doesn't work with composi...

Hi All, I've tried to compile the sources of the Microchip's C compiler for dsPIC: http://ww1.microchip.com/downloads/en/DeviceDoc/mplabc30_v1_20_02.tar.gz Unfortunately after: ./configure --target=pic30 --enable-languages="c" make I get the following error message: cppinit.c: In function `path_include': cppinit.c:191: error: assignment of read-only location make[1]: *** [cppinit....

Hi Well, searching the web to make a fact based decision conserning which platform would have the best performance, PIC32 or Cortex M series does not provide consistent answers. Some sites provides graphs/tables that ARM has the upper hand, and others that microchip has So, what's the deal. Any golden answer? Performance: CoreMark uA/MHz Code size Portability Etc Thanks K...

I have a number of older PIC projects that were written using Parallax assembly mnemonics for the 16C56 and 16C57, and I need to firstly convert the source code to Microchip mnemonics, and then make the programs run on newer PIC's with flash memory instead of OTP. I've spent quite a bit of time googling to try to find a program to do (or help me do) the source code translation, without much...

We are using Microchip's latest ZigBee development kit & are esperienceing problems. The simplest failure happens when the connection gets dropped between a single receiver / tranmitter pair. Once the connection is dropped, the connection never gets reestablished, no matter how close the receiver / transmitter pair. The lowest level of the Zigbee stack is enabled & none of the higher levels ...

I am trying to find a UK distributor for the Microchip MCP41010 digital potentiometer. This is an 8-pin dil chip containing a 256-step 10k pot controlled by an SPI interface. So far I have only found the device in Farnell's catalog but, unfortunately, only in surface mount format (I want 8-pin dil). Can anyone suggest a UK supplier or, alternatively, an equivalent device from anothe...

I'm in the process of choosing between either using Microchip's C18 compiler or the CCS compiler. I've read the comparisons as far as features go and both are comparable although CCS does seem to have somewhat more features. But one of the really big factors is simply how big the developer communities compare. How much sample code is there on the web for both compilers. When I google the k...

Microchip controllers are very cheap, and the tools needed to start developing applications are the cheapest existing today! All you need is the ICD2 Programer/Debuger tool, about 200 USD, and a good tutorial book. The ICD2 is a tool which you can use for a very large range of Flash processors (possibly over 200), and the tutorial book explains how to write firmware for any microcontroller of...

Microchip PIC32 MCUs can be used for graphics applications (as I read on their website), but I couldn't understand if they have a real integrated TFT controller (as in LPC MCUs by NXP) or a different thing. I would prefer NXP's versus Microchip's solutions for many reasons: - ubiquitous ARM core (instead of MIPS) - true integrated TFT controller - lower cost (I'm not sure on this) Bot...

I have a Microchip ICD 1 in circuit programmer/debugger that I've been using for awhile now. My new computer only has USB ports unfortunately, and the ICD is only serial. I bought one of those Belkin USB -> serial port converters, but MPLAB doesn't seem to recognize the ICD. I've confirmed the correct port and speed settings. Is there something I'm missing? Does the USB-> serial converter

Hi all, I am using PIC16F88 as an I2C slave. I have attached the code that I used. From the Microchip MPLAB ICD 2, I find that I am able to detect the start and stop conditions. But I find that SSPSTAT is not getting set. The program is getting stuck in the "gnb" loop. From the Microchip ICD2, I can see that SSPSTAT and SSPSTAT get set after the Start and Stop condictions. But no
