Hello, I saw the post about the new avr studio release and, as it can be uised as IDE for winavr could not resist. Everything seems fine, but when, after compiling, I upload the code to the ATTiny26 on the STK500 with "Use current simulator flash memory", the upload takes a fract

I see from a note I read somewhere that CAN bus wants a nice round number for it's baud rate, and only allows 1.5% error... which means using a 12M or 16M XTAL and dividing down. Sadly I want to run on 3V3 and even 12MHz is outside the safe operating curve at this voltage. Can an

I want to put a row of 3 of these devices down... I assume I should put a XTAL on the first, and run the at others off it's CLKO signal... I need to program them all... I am told I can both program and debug on a JTAG chain... has anyone done it, and does it work? the 12V only ge

2005-10-05 by David Collier
A bit off-topic ... but can anyone tell me if it is possible to build a CAN device which doesn't use a 5V rail? I can buy controllers that run off 3V3... do I HAVE to run the transceivers off 5V, or are there ones that also run off 3V3? Or can I rely on the can cabling to supply

Perhaps the original sender was wondering how to tell if the BLOCK of data is finished. If this is the case, you have to design a "protocol". It might be as simple as "A gap in the transmission lasting at least one character time denotes the end of the data." Otherwise, you might

SPI programming of lots of chips on a single board would be a challenge because, somehow, you have select one out of many. The reset line functions as a sort of chip-select and implementing that, with some sort of logic on your panel seems like a looser. The company I used to wor

Yes, what you describe is what is happening. I don’t think there is any way to keep Astudio from erasing the boot block. Fortunately 0xFFFF appears to be a NOP so even though the reset vector is in the BL, the processor will eventually wrap and start executing the application cod

I use Bascom as well, mainly because I'm too lazy to write it in C, and because I find it easier, and it's great. I recognize the versatility of C and I'll get there eventually, but Bascom's excellent and quite powerful in the meantime. As to the user group here on Yahoo, it does

You bet, AVR-GCC works just fine on the freeBSD system of Mac OS X. You can even use AVRDude as the programmer over a USB/serial port converter. DLC Richard Austin wrote: > As a very newbie, isthere any software for AVR's that allow development > on Macs? I've had a search of for

Just my penny worth in that I certainly found Bascom an excellent way to start with the AVR. The restrictions with regards to variables did seem odd at first, but a small price to pay for an easy intro. Regards. Doug Locke -----Original Message----- From: AVR-Chat@yahoogroups.com

I am surprised by the level of venom regarding the BASCOM support. The complaints sound oddly self-referential... I must admit, however, I rarely use the support forum since I found BASCOM so easy to use. The only time it got a little difficult was trying to write my own library

I'm locking at building a design which would use an ATtiny25, and a couple of transistors on a tiny PCB. The chip is really cheap, but I don't want to spend double that on getting it programmed and tested. Naturally these would be built in a panel, maybe even 256-off on a single

As long as the ATmega32 is in a DIP package and its cheaper, just go for it. That's strange though, in indonesia ATmega32 is more expensive. What country do you live in? On 10/1/05, jdelgadillo66 wrote: > Hello, > > I want begin microntroller project that have more than 8k like a

It depends on what the modem is "talking to". If it is a conventional modem, then there may be a series of handshake steps to establish the correct baud rate. There is more to the modem protocol than just the bit decoding - the arbitration, as it is called, is also a big part. Yo
