Software Hint
DAvE doesn’t change code that is inserted in the ‘USER
CODE’ sections if you let DAvE regenerate the code.
Therefore, whenever adding code to the generated code,
write it into a ‘USER CODE’ section.
The code you really have to add looks like this:
while(1)
{
// USER CODE BEGIN (Main,4)
BlinkLED();
// USER CODE END
}

2.) Check DAS status
1. Start DAS device scanner
2. Start DAS Server Control panel
3. If DAS device scanner does not show any device, start the
appropriate DAS server
Incase you are connected via the USB Wiggler box,
then start „JTAG over USB Box“
Incase you are connected via the FTDI chip or mini wiggler,
then start „UDAS“
