Action

Write bytes into memory.

 

 

Syntax

CmdMemWrite ptr, num,

 

 

Remarks

ptr	The memory address to be written
result	Number of bytes to be written

 

The data byte should immediately follow in the command buffer. If the number of bytes is not a multiple of 4, then

1, 2 or 3 bytes should be appended to ensure 4-byte alignment of the next command, these padding bytes can have any value.

The completion of this function can be detected when the value of REG_CMD_READ is equal to REG_CMD_WRITE.

Caution: if using this command, it may corrupt the memory of the FT800 if used improperly.

 

 

Example

' Pseudocode
' To change the backlight brightness to 64 (half intensity) for a particular screen shot
...
CmdSwap ' finish the display list
CmdDlStart ' wait until after the swap
CmdMemWrite REG_PWM_DUTY, 4 ' write to the PWM_DUTY register
