我是编程 ATtiny 芯片的新手。我在 Arduino 上运行了与此等效的程序并且它可以工作，但是在 ATtiny2313 上运行它时，虽然没有出现错误消息，但程序似乎冻结了。所有 PORTB 都连接到 LED，当程序运行时，备用 LED 亮起，但随后它们保持亮着而不是交换。
我正在使用 makeFile、AVRdude 和 USBtinyISP 程序员对 ATtiny 进行编程。
我认为程序一定有一些问题，我将非常感谢任何帮助。
谢谢

#include <avr/io.h>
#include <util/delay.h>
void myFunction(int status){
if(status==1){
PORTB = 0b10101010;
}else{
PORTB = 0b1010101;
}
int i;
for(i=0; i<100; i++){
_delay_ms(10);
}
return;
}
int main(void){
DDRB = 0xFF;
while(1){
myFunction(1);
myFunction(0);
}
return 0;
}
我的 Makefile 是：
DEVICE = atmega8
CLOCK = 8000000
PROGRAMMER = #-c stk500v2 -P avrdoper
OBJECTS = main.o
FUSES = -U lfuse:w:0xe4:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m
# ATMega8 fuse bits used above (fuse bits for other devices are different!):
# Example for 8 MHz internal oscillator
# Fuse high byte:
# 0xd9 = 1 1 0 1 1 0 0 1 <-- BOOTRST (boot reset vector at 0x0000)
# ^ ^ ^ ^ ^ ^ ^------ BOOTSZ0
# | | | | | +-------- BOOTSZ1
# | | | | +---------- EESAVE (set to 0 to preserve EEPROM over chip erase)
# | | | +-------------- CKOPT (clock option, depends on oscillator type)
# | | +---------------- SPIEN (if set to 1, serial programming is disabled)
# | +------------------ WDTON (if set to 0, watchdog is always on)
# +-------------------- RSTDISBL (if set to 0, RESET pin is disabled)
# Fuse low byte:
# 0x24 = 0 0 1 0 0 1 0 0
# ^ ^ \ / \--+--/
# | | | +------- CKSEL 3..0 (8M internal RC)
# | | +--------------- SUT 1..0 (slowly rising power)
# | +------------------ BODEN (if 0, brown-out detector is enabled)
# +-------------------- BODLEVEL (if 0: 4V, if 1: 2.7V)
#
# For computing fuse byte values for other devices and options see
# the fuse bit calculator at http://www.engbedded.com/fusecalc/
# Tune the lines below only if you know what you are doing:
AVRDUDE = avrdude $(PROGRAMMER) -p $(DEVICE)
COMPILE = avr-gcc -Wall -Os -DF_CPU=$(CLOCK) -mmcu=$(DEVICE)
# symbolic targets:
all: main.hex
.c.o:
$(COMPILE) -c $< -o $@
.S.o:
$(COMPILE) -x assembler-with-cpp -c $< -o $@
# "-x assembler-with-cpp" should not be necessary since this is the default
# file type for the .S (with capital S) extension. However, upper case
# characters are not always preserved on Windows. To ensure WinAVR
# compatibility define the file type manually.
.c.s:
$(COMPILE) -S $< -o $@
flash: all
$(AVRDUDE) -U flash:w:main.hex:i
fuse:
$(AVRDUDE) $(FUSES)
# Xcode uses the Makefile targets "", "clean" and "install"
install: flash fuse
# if you use a bootloader, change the command below appropriately:
load: all
bootloadHID main.hex
clean:
rm -f main.hex main.elf $(OBJECTS)
# file targets:
main.elf: $(OBJECTS)
$(COMPILE) -o main.elf $(OBJECTS)
main.hex: main.elf
rm -f main.hex
avr-objcopy -j .text -j .data -O ihex main.elf main.hex
avr-size --format=avr --mcu=$(DEVICE) main.elf
# If you have an EEPROM section, you must also create a hex file for the
# EEPROM and add it to the "flash" target.
# Targets for code debugging and analysis:
disasm: main.elf
avr-objdump -d main.elf
cpp:
$(COMPILE) -E main.c
这是默认文件，我没有更改任何原始设置。
