In the Electrical Characteristics section of the mpl3115a2 data sheet (page 6),
item 14 is the Turn-on time. In 128os mode, it's specified at 1000 ms.
This is the amount of time you have to wait for "valid data" after exiting
standby mode and entering active mode.
I don't see this delay implemented in any of the sample mpl3115a2 drivers posted on
the internet or on this website. I would expect to see code as follows, with a 1000ms
delay after leaving standby and entering active mode:
I2C_WriteRegister(MPL3115A2_I2C_ADDRESS, CTRL_REG1, 0xB9); // Active altitude mode, OSR = 128
// then toggle the one-shot, wait for Data Ready, and read the data.
Is the Turn-on Time specification real, or can it safely be ignored ?
Also can the forum Moderator please contact me. I set my profile
to use my "handle" instead of my name, but this setting is ignored.
