Four LEDs are provided (D1 to D4). They are available on DIO0 to DIO3 of the SED-M0x
module. Each of the LEDs are active low. See Table 1 for Sedona app interface information to LEDs.
Table 1. LED outputs, Sedona app component information
LED | Sedona component interface | |
---|---|---|
kit:component | slot=value | |
D1 | basicIo:DioOut | dioNum=0 |
isInput=False, invert=True | ||
D2 | basicIo:DioOut | dioNum=1 |
isInput=False, invert=True | ||
D3 | basicIo:DioOut | dioNum=2 |
isInput=False, invert=True | ||
D4 | basicIo:DioOut | dioNum=3 |
isInput=False, invert=True | ||
Tip: To test drive a DioOut for a LED, link its “in” slot to the “out” slot of a DioIn set up to read one of the onboard pushbutton switches (SW1 or SW2). See Table 2. |
Four momentary pushbutton switches are provided; see Table 2 for Sedona app interface information.
Table 2. Pushbutton switches, Sedona app component information for SW1 and SW2
Switch | Sedona component interface | |

kit:component | slot=value | |
SW1 | basicIo:DioIn | dioNum=8 |
isInput=True, invert=True[a] | ||
SW2 | basicIo:DioIn | dioNum=9 |
isInput=True, invert=True | ||

[a] DioIn slot “invert” must be True for an open (unpressed) switch to have an out slot value of False. |
When the device is starting up (after power on or a reset), pushbutton switches operate in combination on the Sedona Dev Board
as outlined in Table 3. Once the device is running, pushbutton switches are controlled by the Sedona app.
Table 3. Combination usage of pushbutton switches on Sedona Dev Board
Function | Switch sequence |
---|---|
Restart with fallback app (debug output directed to RS-232 port) | Hold down both SW1 and SW2 before pressing Reset (SW5). |
Place Dev Board in “program mode” to receive flash download via RS-232 serial port (using “flasher” utility of Workbench’s Jennic Serial Port Tool). | Hold down Program (SW7) before pressing Reset (SW5). |
