Hi,

See the datasheet, page 254: Print #1 , "BAUDCTRLA = " ; Bin(usartc0_baudctrla) ; " DEC= " ; Usartc0_baudctrla
Print #1 , "BAUDCTRLB = " ; Bin(usartc ...

(This is something to be verified).

A driver that lacks a valid digital signature can't be
installed on 64-bit versions of Windows.

Is the new size of the file tvicport64.sys related
with th ...

In my opinion the user should have the choice to decide to install
the driver or not depending if the parallel port is used or not as
interface for the ISP programmer. This can be done if you remov ...

Hi Mark,

Under \SystemRoot\SysWow64\Drivers\ I only see the file TVicPort.sys.
(There are other files there but TVicPort64.sys is not present).

Hi,

I am in the process of installing Bascom AVR on a new PC with Windows 7 Ultimate 64-bit (SP1).
(Intel i7 2600K / 16 GB RAM).

I don't need to run a programmer via parallel port (I use the st ...

(One way to do that).

AVR Studio 4 (current version is 4.19) can store FLASH and EEPROM contents,
fuses and lockbits in a single ELF file. (ELF Production File Format). [url=http://support.atmel. ...

I am not sure that the question was:

Can an AVR set its own fuse bytes at runtime?

(The answer is no).

@MWS:

The difference between the tolerable output and input ranges is called
the noise margin of the gate. If you need information about TTL gates

Can we have more than 20mA on an I/O pin at 5V? If we are driving logic gates it is
not recommended because Vout-L or Vout-H might be out of specifications.

@hgrueneis:

My theory is just that at 5V with the recommended 220 ohm
series resistor the I/O will be OK. Even if you replace
the LED with a jumper, the current flowing through the I/O
will nev ...

At 5V the current flowing through a LED with a 220 ohm or a 470 ohm
series resistor is below the current ratings of the I/O of an AVR chip.
We are driving one or two LEDs so the current will never ...

@MWS:

Stop criticizing the solutions posted by other users and
try to propose something on your own, if you can.

Best regards,
