## Preface Today this is a flash read and write test. The AT32F425R8T7-7 has 64K flash space. ## Flash memory structure The flash memory controller (FMC) provides all the functions required by the on-...
I have seen two forms of mapping in the driver routines introduced. One is using MmMapIoSpace, and the other is using VirtualAlloc. For example: ELECTROMOTOR_GPACON=(ULONG)[color=#FF0000]MmMapIoSpace[...
The PCF8594 datasheet says that Pin 7 (PTC) must be connected to either VDD or left open-circuit. However, in practice, when we use it, Pin 7 (PTC) is either connected to VDD or pulled up with a 5-10K...
As I continue to learn, I have simplified an example that comes with the development board to avoid looking scary. . . .This is it, let the 4 LEDs connected to PORTD light up separately.
