SS [A] [012345678 any combination or order] => read specified ADC
channels once
This command reads the specified ADC channels once.
SS => repeats last SS command
This command repeats the last SS command, without the need to retype the whole thing.
SSI [ADC | DAC | EEPOT | PORTS | SDCARD | SF | WLAN] [bit rate: bits/
second] => Set selected SSI bit rate
This command allows you to view information about and set the bit rate for all devices that communicate
over an SSI port (SSI is the Stellaris name for SPI). Any new rate takes effect immediately. For example:
Device Rate(Hz) Pol Pha Format
------ -------- --- --- ------
ADC 10000000 0 0 Freescale
CPLD 10000000 0 0 Freescale
DAC 1000000 0 0 Freescale
EEPOT 1000000 0 0 Freescale
EEPROM 10000000 0 0 Freescale
PORTS 10000000 0 0 Freescale
SDCARD 10000000 0 0 Freescale
SF 10000000 0 0 Freescale
WLAN 10000000 0 0 Freescale
With an 80 MHz clock, the highest bit rates that are supported by the processor hardware are:
1. 40,000,000 Hz (no SPI peripherals work at this speed)
2. 20,000,000 Hz
3. 13,333,333 Hz
4. 10,000,000 Hz
5. 8,000,000 Hz
SSID [case-sensitive string] => Set SSID
This command allows you to view and set the SSID. The new SSID will be effective after the next Join to
an Access Point. An SSID is the name of a wireless local area network. SSIDs are case sensitive text strings.
The SSID is a sequence of alphanumeric characters (letters or numbers). SSIDs have a maximum length of
32 characters.
STACK => Print stack available message
This command allows you to view how much of the processor stack is free. Whenever a new low in stack
bytes free occurs that is less than 1024 bytes this message will also appear without the command being
typed. For example:
>stack
STACK: 1184 of 4096 bytes free
STATS => Print packet statistics, [0] to clear
This command prints how many total packets, dropped packets, the maximum length of event that have
occurred since power up or the last STATS 0 command in MicroSD writing (due to write latency) and UDP
packet transmitting (due to flow control), and the average length of event. For UDP packets this command
also prints the average flow control event duration, how many flow control events occurred, and how many
times the WLAN Module locked-up and had to be reset. For example:
>stats
00:03:54 CARD Packets: Generated= 200,678 Dropped= 0 Write Latency: Max= 92 mS Mean= 1.406 mS
00:03:54 WLAN Packets: Generated= 200,678 Dropped= 0 Flow Control: Max= 92 mS Mean= 11.178 mS Events= 2,278 Module: Lock-Ups= 0
