Description
The
MP23DB02MM
is an ultra-compact, low-power, omnidirectional, digital MEMS
microphone built with a capacitive sensing element and an IC interface with optional
stereo configuration.
The sensing element, capable of detecting acoustic waves, is manufactured using a
specialized silicon micromachining process dedicated to produce audio sensors.
The IC interface is manufactured using a CMOS process that allows designing a
dedicated circuit able to provide a digital signal externally in PDM format.
The MP23DB02MM offers multiple performance modes enabled by different clock
frequency ranges (power down, low power and normal mode). The device has a
narrow sensitivity range of ±1 dB, high SNR and low distortion for all operative
modes.
The MP23DB02MM is available in a bottom-port, SMD-compliant, EMI-shielded
package and is guaranteed to operate over an extended temperature range from
-40 °C to +85 °C.

I would like to ask about the color display of LCD on wince;
The LCD is 18-bit, but the display driver does not have 18-bit, so it can only be set to 16-bit. In this way, some colors are lost. When scanning to the LCD at 18-bit, RGB565 becomes RGB666, and the R...
