Ie create generic function to handle wire.transmission to simplify Loop code.

See jgc/falco_sw_ard_tft#20

ie particle.publish reports.

Appears to have been resolved?

Add 'Particle.variable' for number of 'unpublished reports', e.g. when wifi is disconnected.

Values (int, char) where value mod 4 = 1 received as x -1 on photon.

https://docs.particle.io/reference/firmware/photon/#attachinterrupt-

See jgc/falco_sw_ard_tft#18

Add SYSTEM_MODE(SEMI_AUTOMATIC) to allow code to run if no wifi is present at restart.
[https://docs.particle.io/support/troubleshooting/mode-switching/photon/#semi-automatic-mode]

Also add:

• Particle.connect() - Connect to cloud and calls connects wifi if necessary.
• WIFI.ready() and Particle.process() -

Consider use of button_status to measure duration of press [https://docs.particle.io/reference/firmware/photon/#system-events]

button_status:
128 button pressed or released
the duration in ms the button was pressed: 0 when pressed, >0 on release.

See example of button_status code [https://github.com/particle-iot/device-os/pull/611]

Also see:
button_final_click:
8192 sent after a run of one or more clicks not followed by additional clicks. Unlike the button_click event, the button_final_click event is sent once, at the end of a series of clicks. int clicks = system_button_clicks(param); retrieves the number of times the button was pushed.

Seems to appear if if semi_automatic mode used. Not tested with semi_automatic and system_thread(enabled).

Appears to be a Windows 10 issue (strange though that appeared with 0.4.9)

[https://docs.particle.io/reference/firmware/photon/#software-timers]

See jgc/falco_sw_ard_tft#19

Node 2 appears to jump to node 5 (note node 4 is fixed), node 5 jumps to node 6 correctly

#4

Add:

• Particle.syncTime [https://docs.particle.io/reference/firmware/photon/#particle-synctime-]
• handle situation where device either:
  • starts up disconnected from the web and then reconnects, or
  • disconnects and then reconnects after a significant period.

Assume for initial version that RTC not used as no battery backup. Millis() returns the number of milliseconds since the device began running the current program. This number will overflow (go back to zero), after approximately 49 days.unsigned long time = millis(); Note: The return value for millis is an unsigned long, errors may be generated if a programmer tries to do math with other datatypes such as ints. NB: Need to set time zone for Time.timeStr(). [https://docs.particle.io/reference/firmware/photon/#timestr-]

#3

jgc/falco_web_server#1

• Add 3 generic int16_1 fields to the radio packet structure to support e.g. current temp, max and min
• Adding 4th to handle e.g. light sensor and / or motion sensor in same transmission.

jgc/falco_ard_temp_sensor#1

Change Payload variables to an array to allow code to be reduced.

Also need to add support to falco_sw_ard_tft

See [https://github.com/jgc/falco_sw_ard_tft/issues/1]

Improve sequencing of data transmissions, ACKs and checks for connectivity

When the base station has no nodes reset the radio encryption key to a random value.

Add:

• millis(0 based timer to avoid issues with time if device starts up without being connected to the web.

Assume for initial version that RTC not used as no battery backup. Millis() returns the number of milliseconds since the device began running the current program. This number will overflow (go back to zero), after approximately 49 days.unsigned long time = millis(); Note: The return value for millis is an unsigned long, errors may be generated if a programmer tries to do math with other datatypes such as ints.

Example (assumes reset within every 49 days):

define ONE_DAY_MILLIS (24 * 60 * 60 * 1000)

unsigned long lastSync = millis();

void loop() {
if (millis() - lastSync > ONE_DAY_MILLIS) {
// Request time synchronization from the Particle Cloud
Particle.syncTime();
lastSync = millis();
}
}

Add 'ifdef' DEBUG_ON, DEBUG_MIN etc to code to reduce size. Note DEBUG does not work as a reserved word.

define DEBUG_ON

Code:

endif

Replace with new device info etc

This will allow node IDs to be re-used without deleting all and starting again. Useful if the wrong node is allocated the wrong node ID.

• Arduino Pro-mini connectors as required
  • VCC --> 3.3v
  • GND --> GND
  • CS --> 10
  • RESET --> 8
  • A0 --> 9
  • SDA --> 11
  • SCK --> 13
  • LED --> 3.3v
• TFT connector (spi)
• Arduino Wire Library (I2C) connector [A4, A5]
• I2C pull-up resistors (4.7K, 0805)

Mounting hole/s not required as mounted onto TFT

Also requires hardware change

• Photon connectors as required
• RFM69HW [D2, A1, A3, A4, A5, 3.3v, GND, ANT]
• SMA antenna (tht)
• u.fl antenna (smt)
• i2C connectors (SCL, SDA, 3.3V, GND) [D0, D1, 3.3v, GND]
• Wire (I2C) pull-up resistors 4.7K (0805)
• 2 x input switches with pull-up resistors (4.7K, 0805) and connectors (1 x tht and 1 x copper pads) for external connections [D3, ]
• Mounting hole for use if no external antenna

Add validation to improve display message reliability and reduce change of character corruption. See if wire.transmission can provide a checksum. Consider adding ACK and resend capabilities.

Add number of bytes (length) to Wire.write(data, length) - see https://www.arduino.cc/en/Reference/WireWrite

See https://www.arduino.cc/en/Reference/WireEndTransmission
0:success
1:data too long to fit in transmit buffer
2:received NACK on transmit of address
3:received NACK on transmit of data
4:other error
