Write the data to flash memory
Description
Write the data from serial port to flash memory.
This command can't be used in commands set
If any data already exsited at the writing destination memory space, An erase command must be run before writing, or the data in that memory area will be unusable.
Note: V7 firmware----the address will be remapped into the reserved memory space that reserved by command Reserve flash.
Usage:
|
Direct: |
"FLMWRAL" follow with the L bytes of data |
|
Arduino: |
void flashWrite(uint32_t addr, uint32_t length, const uint8_t * pdata) |
|
C: |
void Digole_flashWrite(uint24_t addr, uint24_t length, const uint8_t * pdata) |
Parameters:
A, addr
The 3 bytes of start address where the memory going to be erased.
L, length
The 3 bytes length of the memory going to be erased
pdata
The pointer to the data that be saved
Return:
none
Example (Arduino):
uint8_t d[4096]={......};
mydisp.flashWrite(65536L,4096,&d); //write 4096 bytes of data address 65536 and 69631
Example(direct)
uint8_t d[4096]={......};
serial.writeString("FLMWR\x01\x00\00\x00\x10\x00"); //send write command
for(uint16_t i=0;i<4096;i++) //write 4096 bytes of data address 65536 and 69631 serial.write(d[i]);
