Hello,
I am new to Bascom-AVR.
My project is to add the Arduino Leonardo in a PS/2-line to use it as a password storage device.
Is there any Bascom-AVR code already published ?
ICould it be possible to drive it using a 4x4 keypad ?

Thanks in advance
Regards
Theo

Hi Theo,
Welcome here !
look at the help from Bascom about PS/2 : CONFIG ATEMU

unfortunately : The PS2 Keyboard and mouse emulator needs an additional commercial addon library.

Hi JP

Thanks for the reply.
When I started the project I have made a program using the Arduino IDE as I found in the web that a serial output i.e via USB is only possible with the Arduino Leomardo (Atmega32u4).
But the Leonardo can only send one letter in the used program as I noticed. Therefore I bought the Bascom-compiler to solve the problem.
Is it possible to use the buffer to read out serially a string containing 8 password letters ? Afterwards it has to be send serially via RS232 which can be converted by hardware.
Regards
Theo

I use Arduino Uno and arduino M2560, so I don't know very well leonardo, but I see in the Arduino site :

Quote:
The Leonardo has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega32U4 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).


and I know Basic Bascom is a complete program with a lot of possibilities for serial communications. and with a long help file Wink you must spend time to learn ! Confused
see the help for "using uart" you can follow the sample about buffer data

the Ischarwaiting() instruction is very powerfull to fill an array of chr.

I use it like that :
another µP send a sentence stating by Chr(254) and stop with Chr(255)

---------------------------
Do
Sentence = "" : Kbyte = 1 : Serialflag = 0
Open "com3:" For Binary As #1
Do
If Ischarwaiting(#1) = 1 Then
Jbyte = Waitkey(#1)

If Jbyte = 254 Then
Serialflag = 1
End If
If Serialflag = 1 Then
If Jbyte = 255 Then
Clear Serialin3 ' note the Clear statement !!!
Close #1
Exit Do
End If
Tabdate(kbyte) = Jbyte 'i fill a array
Kbyte = Kbyte + 1
End If
End If
Loop
L1byte = L1byte + 1
---
---
loop
----------------
then you can fill a sentence with text = mid (........, J, 1)

Take care, in serial communication, we work in Ascii code .
take care about chr(13) chr(10)
use the ";" after print : print "bonjour"; ' print without chr(13 and chr(10)
