Temperature Module Release Notes

General

The Temperature Module firmware is published as Open Source since firmware release V3.1.x. Below you'll find all the changes since that release.

The firmware updates happening in the Openmotics portal (Settings - Update) contain not only the firmware update of the Master, but also the firmware of other modules as well as the updates for the Beagle Bone Black. All these different firmware updates are assembled in a package which get's a general version number. This version number which you see in the portal is not the same as the Firmware Version of the Master. To check which firmware version is installed on the Master or any other module, in the Openmotics portal, go to Settings - Maintenance and open maintenance mode by pressing the Connect button. Type the instruction firmware version to read the Master Firmware version.

Important Notes:

• V6.x.y only works with Gen 3 hardware

V6.0.17

Date: 28/12/2021

Added functionality

• This version supports remote reading/writing of the built-in eeprom.
  • With the CLI instruction "eeprom read", it's possible to read the eeprom content of a remote RS485 slave module
  • With the CLI instruction "eeprom write", it's possible to write the eeprom of a remote RS485 slave module
  • RS485 instruction "Read Slave Eeprom" have been added
  • RS485 instruction "Write Slave Eeprom" have been added

V6.0.16

Date: 28/11/2021

Added functionality

• This release will allow factory reset initiated by the Master processor (Master Firmware V1.0.115 or higher)
  • Broadcast FR has been implemented
  • When this broadcast is received and the bus is in "discovery mode", then the module will erase itself

V6.0.15

Date: 26/10/2021

Resolved bugs

• During startup, the module can erratically erase it's own network address. This release resolves this issue.

V6.0.14

Date: 28/07/2021

Resolved bugs

• For backwards compatibility with GEN2, the firmware also contains the initialisation handshaking protocol for GEN2. In some circumstances, with new modules, the wrong handshaking was used during the initialisation of the module resulting in non-successful module initialisation and non-successful module adding. This issue has been resolved in this firmware.

V6.0.13

Date: 15/07/2021

Resolved bugs

• Master Firmware version V1.0.104 or higher has an improved search mechanism for slave modules: When a new slave module is found during the automatic search, first the Master will check if the Slave module is responding, when positive the Master will request the slave module to program its slave address, after this the slave module will respond to the master that the slave address is programmed and only then the module is added in the Master list.

V6.0.12

Date: 27/06/2021

Resolved bugs

• To better support the automatic search function of the Brain(+), the generation of the address ID's has been modified:
  • Generation of the ID also uses the serial number of the module
  • A timeout based on the serial number is also used before the random value is taken to avoid the same random values between the same modules

Added functionality

• When a new RS485 network with new modules is started, after power up, the automatic search will be started by the master. When a module in not found yet, the status led will be orange. Ones the Master has found a specific module, the status led of that module will become green. In this way, you can follow the modules that are being found during the search.

V6.0.10

Date: 20/05/2021

Resolved bugs

• Modifications in Processor Eeprom logic to support the latest boot loader version

V6.0.9

Date: 10/05/2021

Added functionality

• The processor used in this module contains an Eeprom. This Eeprom is also used to share information between the application and the boot loader. In this release, byte 74 of the processor Eeprom will contain the number of retries the boot loader will use (to jump to application):
  • Every time the boot loader jumps to application, the value of this byte (Eeprom byte 74) will be decreased with 1.
  • After successful jumping to application, the application will reset this value (Eeprom byte 74) to 5 (retries).

V6.0.8

Date: 15/04/2021

Added functionality

• RS485 instruction "FL" has been added to read Firmware Version and serial number
• The necessary logic has been added to read/write serum number by the test system

V6.0.7

Date: 31/12/2020

Resolved bugs

• I2C sensors connected can get blocked due to communication errors and will be restored every 2 hours by power resetting the connected sensors. To avoid this, an i2c reset is performed after each series of I2C instructions.

V6.0.5

Date: 19/10/2020

Added functionality

• Detection of Master type during init procedure so RS485 protocol V1 or V2 can be applied
• Do the necessary modifications to remain backwards compatible with the Traditional master

V6.0.4

Date: 05/10/2020

Resolved bugs

• None

Added functionality

• Changes for the GEN3 hardware
• Changes for the new front panel
• New logic and functions to allow automatic module discovery

V3.1.5

Date: 12/03/2021

Resolved bugs

• RS485 communication was always ended by double CR/LF. Since the "end message" detection is only using the first CR/LF, the second send CR/LF could create a message error. This is resolved in this release

V3.1.4

Date: 31/12/2020

Resolved bugs

• I2C sensors connected can get blocked due to communication errors and will be restored every 2 hours by power resetting the connected sensors. To avoid this, an i2c reset is performed after each series of I2C instructions.

V3.1.3

Date: 20/5/2019

Resolved bugs

• None

Added functionality

• Led saver mode is disabled in other words, the led functionality will remain active even when the Master requested to go in led power safe mode.
