I am using Cube32MX for the implementation of a USB Host + Fatfs to work with a pendrive connected to a stm32f407, generate code for SW4STM32 but in the usb_host.c file generated by Cube32MX the following appears.
#include 'usb_host.h'
#include 'usbh_core.h'
#include 'usbh_msc.h'
/* USB Host Core handle declaration */
USBH_HandleTypeDef hUsbHostFS;
ApplicationTypeDef Appli_state = APPLICATION_IDLE;
/**
* -- Insert your variables declaration here --
*/
/* USER CODE BEGIN 0 */
/* USER CODE END 0 */
/*
* user callbak declaration
*/
static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id);
/**
* -- Insert your external function declaration here --*/ /* USER CODE BEGIN 1 *//* USER CODE END 1 */
/* init function */
void MX_USB_HOST_Init(void)
{
/* Init Host Library,Add Supported Class and Start the library*/
USBH_Init(&hUsbHostFS, USBH_UserProcess, HOST_FS);
USBH_RegisterClass(&hUsbHostFS, USBH_MSC_CLASS);
USBH_Start(&hUsbHostFS);
}
/*
* Background task
*/
void MX_USB_HOST_Process(void)
{
/* USB Host Background task */
USBH_Process(&hUsbHostFS);
}
/*
* user callbak definition
*/
static void USBH_UserProcess (USBH_HandleTypeDef *phost, uint8_t id){/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
}As you can see in the USBH_UserProcess function, the user section number is repeated as well as at the beginning of the code in the dedicated section for the prototype of an external function.
I write a prototype and re-generate the code with Cube32MX prototype is copied inside the USBH_UserProcess function.
Now if I write code inside the user zone in the function USBH_UserProcess when regenerating code with Cube32Mx this erases the written code.
I think the fault is because the user zone number is repeated to one, I think it should be two but that is automatically generated by the Cube32Mx and I can not change it and I lose the code that I write inside that function when I have to
re-generating coded from Cube32Mx.
What would be the solution to the problem?
The Cube32Mx version is 4.19.0 STM32Cube v1.0
Thank you.
