DRV2604L / RAM address

K.Yaita

Other Parts Discussed in Thread: DRV2604L

Hi Team,

My customer would like to use internal RAM of DRV2604L.
I understood I can write RAM_DATA[7:0] at the RAM address(RAM_ADDR_UB:RAM_ADDR_LB).
Then, I have 2 questions.

I believe the selectable value of the RAM address(RAM_ADDR_UB:RAM_ADDR_LB) is 0～2047(0x000 to 0x7FF).
Is my understanding correct?

(2)
The datasheet shows "A waveform identifier is an integer value referring to the index position of a waveform in the RAM library".
Is "waveform identifier" and "RAM address" same meaning?
I believe it but also found "The waveform identifier range is 1 to 127" in datasheet, so I am confused.

Best Regards,

Hi, Yaita-san:

Q1 : the value of the RAM address(RAM_ADDR_UB:RAM_ADDR_LB) is 0～2047(0x000 to 0x7FF).

[Peter] Yes.

Q2:Is "waveform identifier" and "RAM address" same meaning?

[Peter] No. the waveform identifier is the index of the waveform effects. But we can use the index to find out the RAM address of the effects.

Hi Peter-san,

Thank you for your reply!

Q2:
So, I believe "waveform identifier" and "Effect ID(in datasheet P.32)" are same meaning and the range of both are 1～127.
Is my understanding correct?

Best Regards,
Yaita
