I bought a few 20 pin tiny2313 and few mega168 (28 pin) processors, the corresponding olimex boards and both a usb jtag programmer and an isp programmer from sparkfun
I have used avrstudio 4, bascom avr and ponyprog and none of them recognise the chips or boards or give any indication that there is anything on the cable. I am using the serial programmer as the olimex borads do not have a JTAG interface.
Is there some voodo that I have to do. Are there ANY step by step instructions other than a brezzy “works with ponyprog”.
Actually I lie. I just tried it again with ponyprog , the 20 pin board with a tiny2313 and the power LED dimmed a few times in a second. so the software is seeing the board but thows up a “device missing or unknown device (-24)” error.
The critical thing here is the programmer is ponyser. Also the 20 pin board would not program with the LED jumper connected. I used the Blinky.c program and the make file from WINAVR, copied them to c:\blinky, renamed the files to be all lower case, and modified the make file to reference the blinky.c file. I modified blinky.c to look like this
// Blinky.c
#include <avr/io.h>
#include <avr/delay.h>
int main (void)
{
// set PORTD for output
DDRB = 0xFF;
while(1) {
for(int i = 1; i <= 128; i = i*2)
{
PORTB = i;
_delay_loop_2(30000);
}
for(int i = 128; i > 1; i -= i/2)
{
PORTB = i;
_delay_loop_2(30000);
}
}
return 1;
}
so that it uses port B.
Make looked like this
# MCU name
MCU = attiny2313
# Processor frequency.
# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
# Typical values are:
# F_CPU = 1000000
# F_CPU = 1843200
# F_CPU = 2000000
# F_CPU = 3686400
# F_CPU = 4000000
# F_CPU = 7372800
# F_CPU = 8000000
# F_CPU = 11059200
# F_CPU = 14745600
# F_CPU = 16000000
# F_CPU = 18432000
# F_CPU = 20000000
F_CPU = 10000000
# Output format. (can be srec, ihex, binary)
FORMAT = ihex
# Target file name (without extension).
TARGET = blinky
# Object files directory
OBJDIR = obj
# List C source files here. (C dependencies are automatically generated.)
SRC = blinky.c
The blinky.c reference in the makefile was not in the file as it came from winavr examples. That took me a bit to figure out.
Changing the code and make file for the mega168 worked fine but the led port in C (AFAICR). make runs in under a second. The programming takes a few minutes. I am using a comfile http://www.cubloc.com FBID based usb to serial converter , and it works fine.
Notice that I am using com6. When connected first, the virtual com port was number 30 something so I forced that to com6 in XP control panel.
