How to make MMA9553L go into DOZE mode? I try to use an MCU to communicate with MMA9553L by I2C. I'm sure that I2C and other command works fine. As I've read the MMA955xLSWRM, I try to write command {0x12,0x20,0x06,0x01,0x04} to the cfg register, but it shows the same phenomenon with command {0x12,0x20,0x06,0x01,0x00} . The current is still very big. So I want to know, how to make MMA9553L go into DOZE mode? Why I'm wrong? What should I do? My E-Mail is
[email protected] if necessary. Thank you! Accelerometers Re: How to make MMA9553L go into DOZE mode? Thank you for notifying me. By the way, will MMA9555L update to a new FW at the same time? Re: How to make MMA9553L go into DOZE mode? Excellent, FYI, we'll release soon a new FW revision for MMA9553L which reduces significantly the pedometer operating current. I'll email you directly when it will be available. Re: How to make MMA9553L go into DOZE mode? Hi, Jacques Trichet Thank you very much for your help. That PDF is useful. I have deceased the current successfully. Re: How to make MMA9553L go into DOZE mode? Hi, Attached presentation describes how to optimize and reduce MMA9553L current consumption. The most effective means are the following: - autonomous suspend feature of the pedometer application, - doze mode of the sleep/wake application. I hope it will help to solve your issue. Don't hesitate to ask for further details if needed. Regards, Jacques.
