Compile Error when compiling (ugfx_demo_001/ugfx_virtual_keyboard)

[uGFXuser]

Hi I am totally new to uGFX so in order to learn i downloaded  ugfx_demo_001, ugfx_demo_002/and ugfx_demo_003. Example Projects .

for Keil MDK5  

 

However when i try to compile the demo examples i get the same error as below for all three examples  .

C:\Keil_v5\ARM\PACK\Keil\STM32F7xx_DFP\2.9.0\Drivers\STM32F7xx_HAL_Driver\Src\stm32f7xx_hal_rcc_ex.c(251): error:  #20: identifier "LSE_STARTUP_TIMEOUT" is undefined

I am not sure if i have done something wrong or there is another issue .

Has any one else encountered the same problem ?

Can any one please help me with this error .

Many Thanks in advance

Hello and welcome to the µGFX community!

This sounds like a mismatch of the ST HAL versions. Unfortunately, ST used to change their HAL a few times breaking compatibility each time.
I can't look into this the next couple of days. But I'd recommend you to create an STM32F746G-Discovery project in Keil from scratch and then follow our guide on how to add µGFX to an existing Keil project. It's very straight forward. You can always use the demo you have there as a reference as of where to add files and so on.
Here's the guide: https://wiki.ugfx.io/index.php/Using_Keil_µVision_5_MDK-ARM 

Don't hesitate to ask if you have any further questions. We're happy to help wherever we can.

Tht is normally defined in your HAL config file if I'm not mistaken. Maybe the file isn't corretly included here?
