what I did with SE K300 was like this
1. AT+CSCS="8859-1"<CR>
2. AT*EAPP=10<CR>
3. AT+CKPD="[[",20<CR> //capture an image, send
4. AT+CKPD="]]VVVV"<CR>
5. AT+CKPD="[[2C255527776["<CR>//back to "Insert Item"

as far as i know, ultrasonic sensor has a limitation. with my own ultrasonic module, it can detect object if placed more than 10 cms. so you need to change your sensor type.
You use stop timer, then many line instructions, then start timer. its add more time cycles. Don't stop the timer, then reset timer1 value immediately at first line of interrupt service.
Interupsi_timer1:
Timer1 = 3035
Detik = Detik + 1
Writeeeprom Detik , 8
If Detik >= 60 Then...
If the your circuit is always on everyday, you can increase or decrease the clock of rtc as much as the deviation.
From your problem, please do this calibration process e.g. at 0:00:06 AM. If you do the calibration when it's at 0:00:00 AM, then the clock 11:59:55 PM and when it becomes 00:00:00...
haha... but that is a special skill of most cr*ckers, they don't have to write all codes.
I mean it is a secret layer of PCB, at middle layer. Maybe you think it's a kind of secure socket layer :grin:
Yes, but, if they have enough money to break the lock bits, they also have budget to pay a programmer to debug and skip the protection routines (cr*ck it). Add a secret layer will be the best.
After install new battery and connect to computer, when initial code is sent by computer, the uC wiill check timer value (16 bits) and store it to first two byte data at address 12H - 13H. This is only for the first time, not for next operation since at 10H-11H have been filled with special...
You need add paralel RAM and copy that Serial EEPROM data to it. After copying is complete, jump/call it. Or just use IAP type microcontroller with the same steps with the first one. But if all of you did is aimed to update your firmware, using bootlaoder is better.
Timer and Counter? Sorry, i'm not sure what you want. Do you mean, it's like a Digital scoring board? Please try this, you can modify it as you like.
$regfile = "attiny2313.dat"
$crystal = 8000000

Dim Second As Byte

I just look at post #9, and that is awesome design.
As that design add ULN2003, we told HC259 has no current output enough to drive all led in row. If you put 6 pcs, they will go dull, and the brightness can't be the same. When you enter character like : LLLLLL to the display, lowest row is...
if there's no problem, counted value will be updated every 500 ms as the delay. but i usually found TCCR0 value was not fill exactly as we need. On your program, the value of TCCR0 will be &H01, but we need &H06 (maybe it's a bug of BASCOM). This &H01 means you set timer0 as timer with no...
