Touch Sensing on STM32F0

Hi, it is stated in STM32F051 RM that the MCU was designed to work with STM32 TSL. I attempted to build a prject with the TSL, however it supports only STM32L and would not build saying that ''instruction is unsupported''. How do I go about this? Unfortunately RM is not clear on how exactly to use TSC and there are no examples in SPL.

P.S. I'm using STM32F0-Discovery #tsl #stm32f0

Hi, 

I have a little STM32L152RB code generated from CUBEMX, works. Than I add STMTouch_Driver 1.4.3  and errors .. what I missed ? ''RCC_AHBPriph_GPIOA is undefined'' I have headache .. just tell me please

stm32l1xx.h     // Perip.Acc. Leyer Header file V2.1.2 it seems does not work correct 

Please any answer ..

The project (compiler command line) defines 

USE_HAL_DRIVER ??

hi, 

- comman line:  USE_HAL_DRIVER, STM32L152xB- '' GR1 has already been declared in the current scope '' etc.- '' PA2 has already been declared in the current scope '' etc...\..\..\..\32l1-touch-lib\STM32L1xx_STMTouch_Lib_V1.1.0\Libraries\STMTouch_Driver\src\tsl_acq_stm32l1xx_sw.c(79): error:  #20: identifier ''RCC_AHBPeriph_GPIOA'' is undefined- it seems MDK  in building process tied different things or not .. but why .. so I think   I missed parameters .. but where ?

Hi mickey,

You shouldn't include the STMTouch_Lib in the CubeMX generated code. The TSL is developed based on the standard peripheral library. However the CubeMX code is using HAL drivers. You can activate TS using CubeMX as suggested by Syrine in [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Java/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Java/CUBEMX%20-%20code%20-%20add%20TSL%20Lib%20something%20is%20wrong&FolderCTID&currentviews=9]the other discussion.-Mayla-

Dear Mayla,

 STM32Cube_FW_L1_V1.5.0\Middlewares\ST\STM32_TouchSensing_Library  1. In CubeMX I enabled TS as Syrine said (graphicaly)    - CubeMX produce a code without of TS support because CubeMX does not know where it is ..    - In MDK Keil I added STM32_TouchSensing_Library  bc I need it .. so .. I get errors .. ok. 2. you said: You shouldn't include the STMTouch_Lib in the CubeMX generated code !   - does it mean CubeMX will add TS files ? how CubeMX knows where is TS Lib ? aaa ..    - How I know where I have to put TS lib that CubeMX will be able to generate my TS app. ??

Hi mikey,

1- In CubeMX generated code, only the pinout is configured for Touch Sensing  peripheral. The TSL library isn't included.You have to add it manually, and take into account paths of all required files in order to avoid errors like ''undefined variable...''.2- I am speaking about the old TSL available on

http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1743/LN1734/PF258658

: this one is not compatible with CubeMX generated code. And the one that you have to include MANUALLY is STM32Cube_FW_L1_V1.5.0\Middlewares\ST\STM32_TouchSensing_Library.If you have some errors, you may refer to the examples available in STM32Cube_FW_L1_V1.5.0\Projects\STM32L152D_EVAL\Applications\TouchSensing to know how used variables for example are defined.-Mayla-
