Posted on May 17, 2011 at 13:14The problem has been solved, change like this: FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_ENABLE; but I really wonder why the ''WR'' pulse presents 2 times when write data to extern sram through FS...
Posted on May 17, 2011 at 13:14 When I write a data (16bit) to the GRAM of a TFT LCD through the FSMC like this: *(u16 *)(Bank1_SRAM4_ADDR ) = Para; I found that the ''WR'' pin generated two negative pulse,but not one pulse, RS pin(A0) was low when...
