Hi everybody:
Can I program the AVR-H128B with the STK500?
Thanks in advance.
From customer email:
I'm sorry you feel so terse about SFE. We try to help out as much as we can.Let me tell you.
Your organization really sucks.
You do not support the products you sell.
I think your are not be in bussiness too long…
I am recommending to all my friends not to buy from your company.
I will published in BIZRATE a topic about your company.

To answer your question : The AVR-H128 can be programmed by the STK500 as well as the AVR-PG1, PG2, JTAG, and AVR-USB-JTAG.
Please let us know if we can help with anything else,

A very small research on Sparkfun and Olimex sites shows H128 is STKxxx compatible, the schematics are there, also the ICSP connector layout. It does not take much time to get yourself an answer, and for sure doesn’t justify such an attitude.

This is not the only problem.
I received a e-mail from Spark Fun Electronics which tersely suggesting the AVR-128B can ONLY be programmed by the PonyProg.
Look at avr-h128b.pdf.
The first page shows the board layout.
Shows 64 pins 16 per side marked 1 thru 64.
Look the second page, the schematic.
Shows four connectors (16 pins each) labeled CON1 thru CON4.
How you determine in the first page which pin correspond to which connector?
The only reason I complain is I am used to buy products with better documentation.
Is pretty obvious the microcontroller pins are brought to the 4 connectors, as stated by the labels near all pins. Also the ICSP header is clearly labeled, and its pins are described on page 1. Yes the 4 connectors aren’t labeled on the layout but their placement is obvious even at a very fast inspection.
HI:
May be obvious to you.
Please show me in the board layout (page 1 of avr-h128b.pdf) where CON1 is located,
are pins 1-16 or pins 48 - 64?
Hello,
My apologies - we get a lot of emails and get pretty worn thin by Friday.
Thanks for the backup byteworks! It’s really great to have a community helping out - takes the load off us a bit.
Albert - since I have not seen the questions you posed to us in email - I’d like to post them here as I am a bit confused by your earlier post about the AVR-PG1.
I’ve posted your question and a response about the PG1 here : http://www.sparkfun.com/cgi-bin/phpbb/v … .php?t=788.

Because microcontroller pin numbering is followed on CONx , PEN is pin1 on micro and pin 1 on CON1 so CON1 is 1 to 16. Micro pin 17 is PB7 which is pin 1 of CON2 so CON2 occupies pins 17 to 32, ans so on, CON3 is 33 to 48, CON4 is 49 to 64.catanoa:

I just got (2) Olimex boards with ATMega128 chips on them. As I understand it, I need to plug a 2-pin .1" socket with 6.7V DC or greater into the 2 power pins (labeled + and -) on the bottom of the chip. These 2 pins are in a second row, and are the only pins on that inside row.
Then plug the Kanda STK compatible ISP dongle into the ISP 10-pin-header on the top of the board.
Then, I find port A and plug an LED with a resistor between pin 0 on port A and the ground line. Because 0 is high, I send a 0 to turn on the LED and a 1 to turn off the LED. I’ll use a single pin socket to connect to pin 0 on Port A, and I’ll have to run a ground wire somewhere so I can clip onto it. The downside is that even though this gets the chip running so I can turn an LED on and off, it leads to blown chips if you tap the wrong wires togeather.
I’m working on building a board to break out the 128 chip and carrier board to STK style 10-pin headers with 8 data bits, a +5V DC and a ground per port. Building one of those is beyond the scope of this conversation.
Am I wrong?
Thanks!
Andy Out!
