## 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.

I loaded the modified uboot.bin into flash. I added a program to light up the LED in the start.s file and also added a program to light up the LED in the header of start_armboot. But why does the prog...
Moderator, the chip I use is LPC1766, and the transceiver is TJA1050, which can send and receive data. I use UART3 to send a frame of 9 bytes of data, and my lower computer will reply me with 11 bytes...
