Serial Communication ATTiny13A (#1)

ATTiny didn't come with TX/RX Pins, so I have to make it by myself. 

Got it from http://www.bot-thoughts.com/2012/12/attiny-software-serial-tx-in-assembly.html

Slightly modify it because avra didn’t compile it original source

.include "../tn13Adef.inc" ; definitions for ATtiny13A

.cseg

.org 0x00

rjmp start ; executed after reset

start:

    ldi r16, 0x6D ; 'm' 

    ldi r17, 8 ; put 8 in counter register

txloop:

    lsr r16 ; shift off the next bit, LSB first

    brcs Send1 ; if it is 1 (C=1) then send 1

Send0:

    cbi PORTB, PB0 ; send a 0=low

    rjmp BitDone

Send1:

    sbi PORTB, PB0 ; send a 1=high

BitDone:

    dec r17 ; bitcnt--

    breq start ; if bitcnt == 0, start over

    rjmp txloop ; else do the next bit

Build, compile and upload it

I use USB-to-TTL, and after several fail attempt to compile and upload using usbasp, I’m getting annoyed, so I use hc-05 (a bluetooth module) to communicate with ATTiny. Just connect the RX pin to PB0.

modify it 

note that

        brne L1

will generate error

edit it to

not sure why avra refuse the first formatting

(of course the code above still won't work, it lacks the baud rate :) )

ADC on ATTiny13A with PWM Output in Assembler

Yep, here we are. I use pin B3 as ADC input, and B0 as output. The delay's vary; depend on r16 value, which is ADC value. Since the output's in PWM mode, if we connect LED to B0, the brightness is vary too.

PWM (Pulse-Width Modulation) di AVR memungkinkan output di AVR ATTiny13 berkelakuan seperti analog, dengan resolusi 256 atau, jika dihubungkan ke LED, memiliki 256 tingkat ke-terang-an (redup-terang).

Program diatas menggunakan ADC di port B3 untuk mengontrol tingkat terang-redup LED di port B0

It’s bit different than on http://www.evilmadscientist.com/2007/fixing-a-bad-frequency-fuse-bit-on-an-avr/ because the Attiny13A clock automatically back to 187500 without manual set.

########


Untuk “menghidupkan” lagi AVR yang bermasalah dengan fuse-bit (mungkin kita tidak sengaja mensetting clock terlalu lambat, lebih lambat dari clock USBASP atau ISP kita sehingga program tidak dapat diupload), kita harus menghapus program yang terupload di AVR.

Arduino Nano as Programmer to Upgrade USBASP Firmware [Solved]

This post’s for self doc only. Went to work full day, furiously, in front of My Mac, from Saturday morning to about 7 pm because of single line of warning. 

avrdude: warning: cannot set sck period. please check for usbasp firmware update. 

Yeah, maybe it’s not worth my time but still...  

Anyway, I use my arduino Nano as ISP programmer, to upload the new firmware to USBASP.  

On Arduino IDE, open file, example, ArduinoISP. 

Compile it.

Upload arduinoISP sketch to  Nano. 

Connect the pins. 

Arduino Nano — USBASP

5V — 2

GND — 10

13 —  7

12 —  9 (MISO)

11 —  1 (MOSI)

10 —   5 (RESET)

Don’t forget to connect the jumper J2 or JP2 to enable self programming on USBASP. 

Don’t use 2011’s firmware version, use 2009’s instead

I have two example of command, for windows

avrdude -C ../etc/avrdude.conf -c avrisp -P COM3 -b 19200 -p m8 -v
avrdude -C ../etc/avrdude.conf -c avrisp -P COM3 -b 19200 -p m8 -U flash:r:original_firmware.bin:r
avrdude -C ../etc/avrdude.conf -c avrisp -P COM3 -b 19200 -p m8 -U flash:w:original_firmware.bin
avrdude -C ../etc/avrdude.conf -c avrisp -P COM3 -b 19200 -p m8 -U flash:w:c:\usbasp.atmega8.2011-05- 28.hex

and

avrdude -p m8 -b 19200 -c avrisp -P com2 -U flash:r:usbasp.atmega8.hobbyking.hex
avrdude -p m8 -b 19200 -c avrisp -P com2 -U flash:w:usbasp.atmega8.2009-02-28.hex

Have to modify that to satisfy my Mac environment

I’m sure my Mac have no COM port, and my successful avrdude command is like this

avrdude -p attiny13A -P usb -c usbasp -n

avrdude -p t13 -c usbasp -P usb -U flash:w:template.hex 

so maybe I have to use -P usb

avrdude  -c avrisp  -P usb -b 19200 -p m8 -v

Two codes above have no loop feature, the first code just turning LED connected to PortB0 on. No blink. The second turning LED on on PB0 PB1 and PB2

Try to update the first code to turning on LED connected to PB0, PB1 and PB2

.include "../tn13Adef.inc"

;Pin assignments

;.equ LED = PB0 ;pin 5 of ATtiny13

.cseg

.org 0x00

rjmp loop

and try to disassembly it

The timer's maybe little weird, just my approach to delay by make r17 and r18 to count several time. The code below is tidier timer, :)

.include "../tn13Adef.inc"

.org 0                         

init:

    ldi r16,0b00000100         

    out DDRB,r16                ; PB2 as output

loop:

    sbi PORTB,2                 

    rcall timer                 

    cbi PORTB,2                 

    rcall timer                

    rjmp loop

timer:

    ldi r16,0                   ; these are timer counters

    ldi r17,0

    ldi r18,5

timer2:

    inc r16                     ; do 256 iterations

    brne timer2

    inc r17                     ; do 256 times

    brne timer2

    dec r18

    brne timer2                 ; do 5 times

    ret                         ; return

I love assembler, :)

Kode pertama di atas digunakan untuk menyalakan LED di PortB,0 di ATTiny13A. Kode kedua digunakan untuk menyalakan LED di Pin B0, B1 dan B2.

Kode ketiga menggunakan pola/gaya yang sama dengan kode pertama namun yang dinyalakan kali ini adalah LED di Pin B0, B1 dan B2

Ketiga kode di atas hanya digunakan untuk menyalakan LED sekali saja dan terus menyala, memang ada loop tapi loop tersebut tidak melakukan apapun. 

Untuk membuat led berkedip dalam selang waktu tertentu, kita tambahkan subrutin yang bertindak sebagai time. Bagi saya  agak rumit untuk membuat timer di assembler. Saya belum bisa menggunakan model interrupt, sehingga  saya pakai model loop dengan menyuruh r17 dan r18 berhitung dari 0 sampai f0. Juga tambahkan toggle agar jika led nyala maka dia mati dan sebaliknya
