Action
This FT800 command will send data from the soft stack to the FT800 processor.
Syntax
CMDFTSTACK bts [,opt]
Remarks
|
bts |
The number of bytes to pop from the stack. |
|
opt |
An optional parameter to change stack clean up. When no parameter or 0 is specified, the soft stack will be cleaned up. But when a string is passed you can not clean up the stack since the pointers would point to the wrong address. In such a case specify a numeric value like 2 so the compiler will not clean up the stack. You must clean up the stack before the code returns. You can do this with the ADIW asm command. Please make sure you adjust with the same amount of bytes as you passed. |
