Hi Bruce, Good to hear that you are up again. The HV-programming works dofferent to the normal ISP programming. As I´ve never bothered about the differences I´m sorry to say: can´t explain. But as far as I remember, the timing is not depending on any xtal, thus devices "dead" due

Hi Jim, JW>Have not been able to connect for several hours.. That is absolutely normal for AVRfreaks (every once in a while) Don´t worry it will soon be up again.

Hi, I'm running some code on an ATMega32 (PDIP, 16mHz) I'm using 4 of the 8 ADC channels to collect data from sensors (gyros and accelerometers). These are channels 1,2,3,4 (channels from 0-7). I am, in reality, using only channel 1,3,4 (plan to add a sensor connected to 2 soon).

Correction, Just noted that OSCSEL pins go 3-2-1, and not 1-2-3 as I thought. I had the pins in the correct position the second time, and in the wrong position the first time I tried the HV programming. Bruce Bruce wrote: > >I did say I never done High Voltage Programming didn't

Klaus, Ok, I tried what you suggested below. However, it still failed to work. While looking very closely and repeating the procedure several times, I noted on the STK500 Interface box, a selector called " Programming Mode ". Looking closely, I observed that I had the option of s

Hi Bruce, in case you have (however) accidently tampered the internal program of your STK500 you may restore that as follows: Disconnect any cables from the two ISP connectors Do not insert any device into the programming sockets Press the programming button just besides the ISP-

Thanks to All, Ok, I under the theory that I may have installed an AVR without internal clocks. AVR 1200. I have now installed AVR 8515. Still same problem. On doing a Highvoltage programming, which I have never done before. I get a failure. The title of the failure is the same.

I like working with the AVRs, but just do it for fun. Lately, I have been having a problem. When I connect to the AVR Programer, select the Fuses or Lockbits tabs, I get the error: "ISP Mode Error " I have check to make sure that on the Board tab, that the ISP freq is less than 1

Hi Bruce, try to erase the chip once using HighVoltage programming (with the two 10pin-ribbon cables. Then hopefully everything should be fine again with the 6pin cable. The reason for it might be a wrong programming of fuses (to what ever reason). Good luck! regards, Klaus -- De

Hi you can use a pull up ressistor (internal pul ups can be used) on the slave front for each input pin of spi (MOSI,SCK,SS) and a diode which anode is connected to slave pin and the cathode is connected to the corresponding pin of master. I dont have any idea about MISO pin. wd0

We have a pair of ATMEGA128s talking to each other using SPI. The slave is not always powered on. The problem is when Vcc to the slave is off it gets partially powered by the SPI lines. It appears we could isolate them with optoisolators. But is there a better/cheaper/smaller way

2007-09-01 by Ricardo Callejo
Okay Jim, i found my problem. Suddenly i changed the baud rate to 8MHz and the programs started to run with any baud rate i selected. When i try to think what was happening, i remembered that atmel ships micros programmed with the internal clock. I checked the fuses and eureka!!!
2007-09-01 by Jim Wagner
Ricardo - Odds are your baud rate is not correct. Either the processor clock is not what you think it is, or you are putting an incorrect value into the baud rate generator. Jim On Sat, 1 Sep 2007 10:57:25 -0300 "Ricardo Callejo" wrote: > Hi everyone. > > I follow AVRSTUDIO HELP

Hi everyone. I follow AVRSTUDIO HELP to configure STK500 with ATMEGA168. I flashed some simple programs working with LEDs, switches, timers to verify the system. I find troubles when i work with the UART. I wrote a simple code that works fine with other micros like AT90S4433 or A

There are msny products available for USB interfacing. Just do a Google search for "USB interface". Here's one: http://www.hobbyengineering.com/SectionIN.html For $33, the USB232R looks like a great deal. This is one example of many you can find with a search. Zack On Mon, 27 Aug
