Getting started with the STSW-GLA001V1 software package for
the STEVAL-GLA001V1 evaluation board based on STM32Cube
Introduction
The STSW-GLA001V1 firmware is designed to be used with the STEVAL-GLA001V1 insulated AC
switch control evaluation board to evaluate its embedded TRIACs and AC switches, implementing
different control modes.
The firmware is developed from the STM32Cube embedded software libraries for STM32F0 series
using the IAR Embedded Workbench for ARM.
The firmware also lets you interact with the STEVAL-GLA001V1 hardware user interface and allows the
configuration of some parameters using a PC user interface.
Thanks to the dynamic storage of the configuration parameters in a dedicated section of the Flash
memory embedded in the STM32 microcontroller, you can change any parameter any time without the
need of compiling and programming the MCU via third-party tools.

System setup guide UM2313 Figure 11: STSW-GLA001V1 state machine The different states are: SYSTEM_INIT: initializes all the firmware variables and parameters used as default values, at board power on or after MCU hardware reset. SYSTEM_SWITCH_ON: checks if the ZVS detection circuit is available and/or used and sets the next state as MAINS_PERIOD_DETECTION if the ZVS signal is available or as CONTROL_MODE_DETECTION if the ZVS signal is not available. -
Page 15: Table 3: State Machine Fault Codes
UM2313 System setup guide If the ZVS signal input is not present when zvs_hw = ENABLE, the MainsPeriod detection algorithm restart as soon as the ZVS signal is available. CONTROL_MODE_DETECTION: checks the value of the analog selector called MODE and then sets the GATE_CONTROL_AVAILABLE_IDLE as next state and the related detected operating mode. -

System setup guide UM2313 2.2.1 STSW-GLA001V1 control mode detection In the AC_Switch_Control_Tasks.c file, the MediumFrequencyTasks() function calls the AC_Switch_Ctrl_MODE_Selector_Reading() method, if the actual state is not SYSTEM_INIT, SYSTEM_SWITCH_ON, MAINS_PERIOD_DETECTION and FAULT_ERROR. The AC_Switch_Ctrl_MODE_Selector_Reading() method detects if the MODE selector has been moved from the previous position and so if the actual MODE selector value is changed. -

UM2313 System setup guide Figure 12: ZVS delay principle Real Ideal mains Real td_zvs The TRIAC control synchronization with ZVS has to be accurate in some applications; so, this delay has to be compensated. For this purpose, the TIM6 is used. As mentioned, the td_zvs delay can be positive or negative: in the first case the pulse gate command must be anticipated and in the second case it must be delayed. -
