I implement the eeprom emulation library for the STM32F423 controller and was wondering if the variables are 16 bits can I use the virtual addresses like this: uint16_t VirtAddVarTab[NB_OF_VAR] = {0x1, 0x2, 0x3};Or do I need to keep space like 0x1, 0...

The function USBH_CDC_Receive should check that the parameter length is a multiple of endpoint size.Reason for this that CDC_ProcessReception calls USBH_BulkReceiveData with the argument CDC_Handle->DataItf.InEpSize. So if the argument pbuff passed t...

@Piranha Yeah basically the whole driver is missing. The HAL should only implement a basic abstraction on which the hardware driver should be build upon.What I can agree with is that all ST HALs and drivers are a complete inconsistent mess.

@MJ_1992 Maybe check out this page for implementing Idle detection and the correct way to use the variable "Size". Without source code its hard to judge why your code dosen't work. Link 1: https://controllerstech.com/uart-dma-with-idle-line-detectio...

Try this: https://community.st.com/s/onlinesupportand than new case.Or this: https://www.st.com/content/st_com/en/support/support-home.htmland than open a case.Its a bit hidden.

Usually there is a tab "Product Certifications" under documents.But its missing for the STM32WLE5CCU6.I think you best bet is to open a support ticket directly.

For 2. you could implement a timeout interrupt via a timer that processes the data earlier if data transmission is slow. Make sure to set the interrupt prioritys for dma and timer correct to avoid problems.As your data rate is very slow I would just ...
