[quote:b3f85743ff="EDC"]It back everytime to the same date and time because of this code:
[code:1:b3f85743ff]'setup date

Gosub Setdate
'Setup time
_sec = 00
_min = 12

Gosub Settime [/code:1:b3f85743ff]
Set time once and then remove or remark this code. Then compile and program microcontroller again.
So microcontroller without this part of code will not set date and time back.
Solution for comfortable setting date and time is made some Menu but this can be dificult to You if you ask about this simple "issue" :D
Try at first to read (with understanding) some example codes from Bascom sample folder. Try also forum searchengine.
Some book or even Google know the answears for these basic questions :D[/quote:b3f85743ff]
With the code when compiling the program will update the time but when I turn off my STK500 restarts again with the same time 16:12:00 ok !!
[code:1:b3f85743ff]'setup date
_day = 20
_month = 5
_year = 17
Gosub Setdate
'Setup time
_sec = 00
_min = 12
_hour = 16
Gosub Settime[/code:1:b3f85743ff]
Now without this code as my friend says EDC when compile will update the time but every time it is restarted, the time is not erased .... ok !!
[code:1:b3f85743ff]'setup date
'_day = 20
'_month = 5
'_year = 17
'Gosub Setdate
'Setup time
'_sec = 00
'_min = 12
'_hour = 16
'Gosub Settime[/code:1:b3f85743ff]
Until then we are going well !! I am still reading with the help bascom i2c protocol is very difficult for me. :shock: :shock:

Here you can find the i2c scanner. Perhaps you have to change things like regfile, crystal, config sda en slk. Perhaps you can run this to check if you see your ds1307 is seen on the i2c bus before.
Could you please check it. And let us know?
Have fun

Disable these:

BASCOM-AVR : pass an eeprom variable to sub/function : NEWTOPIC
Hi
i want to pass a variable and its related eeprom variable to sub and by pressing a key save current value of variable to related eeprom variable,how is it possible?
for example

dim param as byte
dim e_param as eram byte
dim m as byte
dim e_m as byte
dim s as byte
dim e_s as eram byte
sub save_to_ee(param as byte,e_param as byte,key_condition)
if key_condition=1 then
e_param=param
endif
end sub
-

-
key_condition=pinb.0
call save_to_ee(m,e_m,key_condition)
key_condition=pinb.0
call save_to_ee(s,e_s,key_condition)

BASCOM-AVR : pass an eeprom variable to sub/function : REPLY
some note:
-compiler dont accept eeprom variables as input argument
-compiler accept eeprom variable as byval
so it make a copy of value of variable and we can not save value to eeprom in sub/functions.
thanks

BASCOM-AVR Old versions : DS1307 : REPLY
You make it very difficult for me. An i2c scanner scans the i2c bus and should display all i2c devices on the bus it finds. Your ds1307 occupies two addresses on hex(D0) and hex(D1. So you should see only that single device.
You are talking about 'Research', I suggest you read some more on the working of i2c. The help of Bascom is very clear on this. In 2014 you were struggeling with the same problem.
Have fun

thanks a lot EDC
i remember that we have some instructions in assembly for find address,why the compiler does not find address by these instruction automatically and write to related address?!
is some limitions on stack or frame or some things else?

BASCOM-AVR Old versions : DS1307 : REPLY
Hi all!!
Does anyone have a manual "How to prepare a BASCOM i2c address from an i2c address?" I would like to read this manual since the help does not appear DS1307 nor example. :D
↧
BASCOM-AVR Old versions : DS1307 : REPLY
The manual/help does mention that bascom i2c address is vendor address shift left by 2. Or multiply by 2.
The i2c scanner will give this info.
if you had done some search on the forum you would have found that too.
The more interesting question is : why does bascom use a different address?
After an i2cstart we must send the address of the slave.
This address has a Read/Write bit at bit position 0, which indicates if we want to read or write.
Thus the 8 bit we must send is A6,A5,A4,A3,A2,A1,A0, R/W
While vendor uses address &H20 for example, we must send it as &H40 because of the R/W bit.
And while R/W is not actually an address, i think it simplifies dealing with I2C since it is always sent as part of the address.

BASCOM-AVR : Simple Sample Programmer : REPLY
a related question about programmers, is any one try to make an isolated spi programmer?
when working near power elements like AC Motor drives, the noise of high voltage switching make computer completely unstable. in some cases my programmer burn. so i want to make an isolated spi programmer.
my programmer connected via usb, and making an usb isolator is very difficult, so i decide to isolate output signals of my programmer.
just some answer will help me, i want to know:
1- does the condition of pins of Mosi-Miso-Sclk-Reset change whitin spi programing or not?
2- same question for Xmega Types, PDI and reset?
if the direction is always same, for example Mosi is always output, then using a optocoupler solve my problem, othervise the solution will be more difficult.
thanks for your answers.

BASCOM-AVR : RTC32 disabling and enabling on AtxMega256A3BU : REPLY
Correction on my previous reply. After having encountered all kinds of sporadic bugs which only occurred for the Atxmega256A3U and not for the Atxmega258a3bu, I discovered that the Rtc_ctrl = 0 command does not stop the RTC and the sectic routine keeps being fired every second.
So for now I am not able to stop / start the RTC on the A3U by syntax.
On the Atxmega256a3bu hoever, the command Rtc32_ctrl.0 = 0 does stop the Rtc32 as sectic is not fired.
So in summary:
Atxmega256a3u: Rtc_ctrl = 0 has no effect as rtc keeps running
Atxmega256a3bu: Rtc32_ctrl.0 = 0 works as rtc32 is stopped.
Any other options to start/ stop the RTC?

EASY TCP/IP : URL2IP issues : NEWTOPIC
Hi,
i happy about the new function URL2IP in the latest Bascom revision. Thats what i never hoped to find.
Regarding to the Help its connecting to Google DNS server 8.8.8.8 , is this changeble to my own internal DNS Server so it works for my internal network.
I used the Wiz510 sample, works fine as it is.
Is the Google server maybe the reason why it does not work for all url names? It works for the "mcselec.com" url from the sample, but many URL do not work even if they respond to a manual request via my PCs command line. One not working example is my page gs400.de; WWW.Bild.de works fine.

BASCOM-AVR : XMega-A1 Xplained - Simple Blink a Led : NEWTOPIC
Hey Guys,
I have written a small program for the Mega-A1 Xplained (uses the CPU ATXMEGA128A1) with the help of the official Bascom-Documentation:
https://avrhelp.mcselec.com/index.html?atxmega.htm
But unfortunately I cant see anything blinking on the chip.
This is my code:
[code:1:a4251bf672]
$regfile = "xm128a1def.dat"
$crystal = 32000000 '32MHz
$hwstack = 64
$swstack = 40
$framesize = 64
Config Osc = Enabled , 32mhzosc = Enabled
Config Sysclock = 32mhz , Prescalea = 1 , Prescalebc = 1_1
Config Porte.1 = Output
Do
Toggle Porte.1
Waitms 500
Loop
End 'end program
[/code:1:a4251bf672]
I cant upload pictures to this Forum, because I do not have at least 4 posts.
As a programmer I use the [b:a4251bf672]ALL-AVR-Programmer[/b:a4251bf672] which the BASCOM IDE recognizes as [b:a4251bf672]USBprog Programmer / AVR ISP mkII[/b:a4251bf672].
The Programming process -by clicking "Program chip (F4)"- executes without errors and reads as follows:

Q: What is the Program and Debug Interface (PDI) ?
A: The Program and Debug Interface (PDI) is an Atmel proprietary interface for external programming and on-chip
debugging of a device.
The XMEGA doesnt have the SPI based In-System Programming (ISP) interface for
external programming, which has been used for megaAVR. Nor does it have the
debugWIRE interface. These have been replaced by a two wire Programming and
Debugging Interface (PDI). [from Atmel App Note AVR1005]
