Hi,
I am developing an application running on STM32F469 MCU to control an LCD
Generating my Code using STM32CubeMX.
Using FMC Memry type is LCD_Interface, A23 Data: 16 bits
The bug I found is in the STemwin_wrapper.c file, in functions : FMC_BANK_WriteData and FMC_BANK_ReadData.
the bug is that the code generated tries to write and read the data from FMC_BANK->RAM and that address is 0x60000002 where it have to be 0x61000000
typedef struct
{
__IO uint16_t REG;
__IO uint16_t RAM;
}LCD_CONTROLLER_TypeDef;
/* The Bank address need to be entred by the USER */
#define FMC_BANK_BASE ((uint32_t) 0x60000000 )
#define FMC_BANK ((LCD_CONTROLLER_TypeDef *) FMC_BANK_BASE)
/**
* @brief Writes register value.
* @param Data:
* @retval None
*/
static void FMC_BANK_WriteData(uint16_t Data)
{
/* Write 16-bit Reg */
*(uint16_t*)0x61000000 = Data; // FMC_BANK->RAM = Data;
}
/**
* @brief Writes register address.
* @param Reg:
* @retval None
*/
static void FMC_BANK_WriteReg(uint8_t Reg)
{
/* Write 16-bit Index, then write register */
FMC_BANK->REG = Reg;
}
/**
* @brief Reads register value.
* @param None
* @retval Read value
*/
static uint16_t FMC_BANK_ReadData(void)
{
return *(uint16_t*)0x61000000 ; // return FMC_BANK->RAM;
}
the issue is that every time I regenerate the code using STM32CubeMX the bug returns and have to fix it again.
is there a way to avoid this bug regenerating or better to fix it from the beginning?
