I'm getting ready to start a project the will be used in an aircraft, we are looking at using an atmega48/88/168 depending on code size and wanted to know if anyone has done this before. If so, what mega avr did you use? -Jim

One way to protect the board from static and other damage is to physically mount it to a piece of sheet metal that is about 10mm larger (length x width) than the board you are mounting it to. Drill the sheet aluminium to accommodate whatever mounting holes are in the Dragon board

I want the routine to end up being named "usart0_Init" and that is what the call instruction uses. The name inside the macro definition has "@0" in it so that I'm hoping the "@0" will get replaced with the value "0" when the macro is invoked, to end up with just "usart0_Init" as

I don't understand. In the code snippet that doesn't work, "@0" is inside the macro definition. Why then does it not get expanded to just "0" when the macro gets expanded with "@0" set to "0", so there ends up being no "@" in the name of the routine? Steve From: AVR-Chat@yahoogro

Is there some restriction about using a macro parameter in a label? The following code will not work. It gives an "undefined symbol: usart0_Init" error: .MACRO _USART_INIT usart@0_Init: .... code using @0 parameter ............ .ENDMACRO ..... call usart0_Init ..... _USART_INIT 0

That setting of CKSEL is for a low frequency crystal. That means 32KHz or so. To recover your chip, you will either need to hook up a 32KHz crystal or connect an external clock signal (maybe about 1MHz). Then you can program it again. Jim > atmega8 > > > _________________________

Hey all, I recently got an AVR Dragon for doing some hobby project. The AVR Dragon is pretty much an uncovered PCB prone to static damage. Can any one suggest me how to protect it from static damage. Any easy method suggested will be much appreciated. Cheers :)

The problem is that studio 4 doesn't support TPI programming, but studio 5 does. Updating gcc is fine, but can we get a firmware upgrade for programming platforms like stk500 to support TPI? Studio 5 isn't quite easy to use as 4, but eventually it worked for me. It appears to me
2012-01-23 by Jim Wagner
Studio5 has been the subject of extended discussion on the AVRFreaks web site. It has the potential for being pretty good, but there are currently many problems. These problems do seem to be repaired over time, but it is awfully slow and does NOT give me great confidence. This is

Jim, I am a hobbyist. Been using Studio 4. Upgraded to Studio 5. I was so disappointed in 5, that I decided 4 wasn't broken and went back to Studio 4. Any idea what the deal with AVR and Studio 5 ? I hope this is not the future. Bruce On 1/21/2012 11:12 AM, Jim Wagner wrote: > Th

Even more important is to verify whether or not you can read the device signature bytes. If you cannot, there are several possible reasons: 1) Bad wiring 2) Bad programmer settings 3) Programmer set for too high clock rate compared to MCU clock. Programmer clock must be less than

Can you post the fuse settings you are using? Most of the time the reason an AVR does not work it because the fuse settings for the osc are wrong. My client had this very issue with a programmer he purchased. Check your fuse settings: Dave... -----Original Message----- From: AVR-

The G540 does NOT work with ISP. You have to remove the mcu from your circuit and put the mcu in the programmer. ISP is "In System Programming" and works with an ISP programmer and your application board. Further, if you look on the list of supported devices, here: http://www.pic

Why is the array in flash? The way you have defined it, it is in SRAM. The data is in flash and is copied into SRAM during boot-up. You access the data through its "image" in SRAM. It is NOT intended for you to access it any other way. Why should you need to when SRAM has everyth
