Program updated: mbed-os5-press_26 - b'Added integration of analog channels, introduced three new setpoints (Pb_1, Pb_2, Tp) for automatic compressor operation. ;'
Alex K - 24 Dec 2021
Program updated: mbed-os5-press_24 - b'The weight is now transmitted in Newtons. For this, two bytes are transferred over the i2c bus instead of one.'
Alex K - 15 Oct 2021
Program updated: mbed-os5-press_23 - b'On the i2c bus, Arduino Nano with address 2, transmits the weight value with a resolution of 1 kg.'
Alex K - 08 Oct 2021
Program updated: mbed-os5-press_22 - b'digital pin 11, pin 12 as an input limit switches are now normally closed. Returned timer_4. He now periodically opens the outlet valve to control water leaks. New variables are openTimeV2_H2O and periodV2_H2O.'
Alex K - 12 Mar 2021
Program updated: mbed-os5-press_21 - b'Removed pc.printf command that sends empty string once per second and associated timer_4, since the operator program was changed, a new operator Loc () was introduced into it. Instead of pc.printf ("Reset ALARM \\ r \\ n") now plotter.printf ("Reset AL'
Alex K - 11 Nov 2020
Program updated: mbed-os5-press_16 - b'Messages transmitted via pc.printf to PC are supplemented with checksums to increase the reliability of communication.The pc.printf command was introduced, which sends an empty string once per second in case of data loss (corruption) during transfer'
Alex K - 11 Sep 2020
Program updated: mbed-os5-press_13 - b'The values of the EEPROM2 settings are displayed in pc.print in a special line with the current diagnostic data.; An additional block has been made in the parser for decoding incoming alarm settings; they are written in EEPROM2.'
Alex K - 19 Jun 2020
Program updated: mbed-os5-press_10 - b'An additional block has been made in the parser for decoding incoming alarm settings for writing to the EEPROM. Additional digital inputs are activated.'
Alex K - 11 Jun 2020
Program updated: mbed-os5-press_7 - b'The flag of the Stop button is accepted - closing of 4 valves,; and the flag of the compressor buttons is a command for discrete output PB_10. The num_chan setting is switching the channel number for the feedback of the controller, written in EEPROM'
Alex K - 04 Jun 2020
Program updated: mbed-os5-press_5 - b'When receiving a command line with a zero sum (empty lines), the flag_zerostart flag is set, and the current settings and values are transferred to the series. These zero settings are not entered into the controller and are not written to the EEPROM.'
