Warning temperature display
The message shown in
Figure 54
is displayed on the LCD when the temperature goes
under the over-limit low value (TEMPERATURE_THYS: Hysteresis Temperature).
You can configure the TOS and THYS using dedicated
#define
statements in the code. By
default, they are set to (see menu.c file):
#define TEMPERATURE_THYS 31
#define TEMPERATURE_TOS 32
Press any key to return to the

HDMI™ CEC submenu
The STM32F100ZET6 microcontroller features an HDMI-CEC peripheral. This
demonstration shows how to configure this peripheral and how to create a CEC network
providing a high-level communication between various devices using CEC protocol
messages.
For more details, refer to application note AN3127
CEC networking using STM32F100xx
value line microcontrollers
. This application note provides a full description of the
STM32F100xx value line embedded HDMI-CEC Controller, and a step-by-step firmware
description of CEC peripheral configuration. An advanced demonstration firmware
communicating in a real multimedia and HDMI environment is also provided to help build the
CEC applications.
When the
HDMI CEC
submenu is selected, the message shown in
Figure 56
is displayed on
the LCD.
