/** onboard_modem_api is a standardizing API for Modem type devices under mbed-os.
|
||
|
|
* It provides a simple hardware abstraction layer on top of the modem drivers
|
||
|
|
* written for mbed-os.
|
||
|
|
*
|
||
|
|
* It is required from the engineers porting any modem type device (e.g., Cellular)
|
||
|
|
* to provide an implementation of this API in their respective target folder as well as
|
||
|
|
* usage of standard PinNames (in PinNames.h) is required. For example,
|
||
|
|
*
|
||
|
|
* MDMTXD = P0_15, // Transmit Data
|
||
|
|
* MDMRXD = P0_16, // Receive Data
|
||
|
|
* MDMCTS = P0_17, // Clear to Send
|
||
|
|
* MDMDCD = P0_18, // Data Carrier Detect
|
||
|
|
* MDMDSR = P0_19, // Data Set Ready
|
||
|
|
* MDMDTR = P0_20, // Data Terminal Ready (set high or use handshake)
|
||
|
|
* MDMRI = P0_21, // Ring Indicator
|
||
|
|
* MDMRTS = P0_22, // Request to Send (set high or use handshake)
|
||
|
|
*
|
||
|
|
* MDM_PIN_POLARITY must also be defined as 0 (active low) or 1 (active high).
|
||
|
|
*
|
||
|
|
* NOTE: This API should only be used when the modem exists on-board, i.e., the modem is
|
||
|
|
* NOT a plugged-in component.
