Integrated Programmer/Debugger
The integrated programmer/debugger allows the user to program the microcontroller and
debug the software applications; it is based on the UDE PLS software.
The debugger serial number is reported on the label applied on the board (bottom side).
The integrated debugger SW is accessible via ST's free integrated development
environment, SPC5Studio (www.st.com/spc5studio). To download the debugger software
and to activate license refer to the PLS website.
A JTAG port allows connecting further HW/SW tools to program and debug the
microcontroller
