## Contents Update History License ## Update History ### V0.1.3 / 23-September-2011 Main changes Add directive for GNU C compiler in stm32l15x_tsl_acquisition.c file Update STM32L15x channel table of MCU resources section of the user manual (.chm) Toolchains and Compilers used during validation KEIL µVision version 4.03, compiler version 4.0.0.728 IAR EWARM version 6.21.1, compiler version 6.21.1.52794 ### V0.1.2 / 02-September-2011 Main changes Bug correction in stm32l15x_tsl_services.c file (ECSTimeStepCounter variable was decremented below its minimum value (0)). Bug correction in stm32l15x_tsl_singlechannelkey.c file (Channel_P3.EnabledChannels was badly affected). Bug correction in stm32l15x_tsl_checkconfig.h file (shield masks for PB4 was wrong). Toolchains and Compilers used during validation KEIL µVision version 4.03, compiler version 4.0.0.728 IAR EWARM version 6.21.1, compiler version 6.21.1.52794 ### V0.1.1 / 20-April-2011 Main changes Bug correction in stm32l15x_tsl_ct_acquisition.c file (RI->HYSCR1 badly configured). ### V0.1.0 / 08-April-2011 Main changes First Beta release. Bugs correction and enhancements: correct the GPIO clock setting in TSL_IO_Init(). add missing enable/disable interrupt in TSL_IO_Acquisition_P1/2/3(). add support of the shield with one pin. remove TSL_RefKey_Process() and TSL_SCKey_SetAcquisitionMasks() functions (not used). replace uint8_t and uint32_t by unsigned in bit fields structures. remove the RTOS feature (not used). remove DriveMask and RejectedNb elements of TOUCH_PORT_Info_T structure (not used). remove unused constants related to RC acquisition. add wait delay during acquisition (CLWHTA and CLWLTA constants). support of the PROTECT_IO_ACCESS feature. remove IT_SYNC feature (not used) in the configuration file. change the device name supported in the configuration file. remove MCKEYx_LAYOUT_TYPE in the configuration file. rename PIN_SHIELD by ACTIVE_SHIELD_CHANNEL in the configuration file. code clean-up. Toolchains and Compilers used during validation KEIL µVision version 4.03, compiler version 4.0.0.728 IAR EWARM version 6.10.5, compiler version 6.10.2.52244 Known limitations If the DxS feature is enabled, the Debounce Filter must be >= 1 (i.e. if at least 2 channels have their DxSGroup parameter different from 0). The Recalibration timeout is 1s accurate (i.e. for 2s specified, the RecalTimeout will be between 1s and 2s). Inlining functions are not yet supported by IAR compiler when referencing global variables. USE_INLINED_FUNCTIONS has also no effect when IAR compiler is used. The 3 electrodes of a MCKey must have the same channel number. Only the interlaced electrodes layout is supported for MCKeys. The GROUP6 (PB4 and PB5) is not usable due to a poor sensitivity. ## License By using this Licensed Software, You are agreeing to be bound by the terms and conditions of this License Agreement.
