nanoMODUL-164 QuickStart Instructions

PHYTEC Meßtechnik GmbH 2003 L-379e_4
The demo application within the file hello.h86 initializes the serial
port of your nanoMODUL-164 to 9600 baud. The initialization values
are based on the assumption that the microcontroller runs at a 20 MHz
internal clock frequency. Please note that the nanoMODUL-164 is
populated with an oscillator with a frequency of just 5 MHz. An
internal PLL (Phase Locked Loop) device renders an internal 20 MHz
clock frequency. If your nanoMODUL-164 is equipped with an
oscillator with a different frequency value, the demo application
might transmit using another baud rate. This may lead to incoherent
characters appearing in the HyperTerminal window following
execution of code. Additional information can be found in the
readme.txt file in the Hello project directory.
2.3.2.2 “Blinky“
The ‘Blinky’ example sends a program to the Flash that, when
executed, manipulates the single user SMD-LED D1 on the
Development Board that is mounted near the Boot (S2) switch. This
second example program provides a review of the FlashTools
download procedure:
•
Ensure that the target hardware is properly connected to the host-
PC and a power supply
•
Reset the target hardware and force it into Bootstrap mode by
simultaneously pressing the Reset (S1) and Boot (S2) switches on
the Development Board and then releasing first the Reset (S1) and,
several seconds later, releasing the Boot (S2) switch
•
Start FlashTools for DOS from within the PHYTEC Rapid
Development
Kit|nanoMODUL-164 program group. For
connection to the target hardware, remember to select the icon
corresponding to the correct serial port on your host-PC
•
After the loading process has finished and the main FlashTools
menu appears, enter ‘2’ to choose the Erase entire Flash-Area
command. Select ’Y’ to confirm erasure of unprotected sectors of
Flash memory.
