Description: Work on TM1638 driver is in progress,

It seems that this TM1638 is using one segment per digit, see datasheet section: This is different from TM1637 I tested in the past, which was using one grid per digit:

Build 1.17.34 and this command Code: text Expand Select all Copy to clipboardbacklog TMGN_Clear; TMGN_SetBit 0 0 1 ; TMGN_SetBit 0 1 1 ; TMGN_SetBit 0 2 1 ; TMGN_SetBit 0 3 1 returns this: Added after 20 [minutes]: Progress report with build 1.17.35: Code: text Expand Select all Copy to clipboardbacklog TMGN_Print 0 0 1; TMGN_Print 1 0 2; TMGN_Print 2 0 3; TMGN_Print 3 0 4; TMGN_Print 4 0 5; TMGN_Print 5 0 6; TMGN_Print 6 0 7; TMGN_Print 7 0 8 Also mapping works: Code: text Expand Select all Copy to clipboardTMGN_Map 7 6 5 4 3 2 1 0 LED control is solved, now input switches

this commit: introduces a TM1638 driver wrapper. Right now, all TM1637, TM1638, and GN6932 should work through a single driver implementation, although so implementation details may be different from chip to chip. The TM1637 is I2C-like (but it's like a modified I2C standard, idk why manufacturer went that way) The GN6932 and TM1638 is SPI-like

Build 1.17.43 progress: Keys can now be read with TNMG_SetupButtons [value_in_milliseconds] command - typical 100mS Log should be something like this:

I've added ability to fire events for TM1638 buttons: Code: text Expand Select all Copy to clipboard addEventHandler OnCustomDown 1 echo Button 1 is going down addEventHandler OnCustomUp 1 echo Button 1 has been released

It looks like it is working, see the picture. Added after 9 [minutes]: addEventHandler OnCustomDown 1 TMGN_Brightness 1 addEventHandler OnCustomUp 2 TMGN_Brightness 7 or entire script for testing: Code: text Expand Select all Copy to clipboardstartDriver NTP ntp_timeZoneOfs +2:00 TMGN_Clear addEventHandler OnCustomDown 1 TMGN_Brightness 1 addEventHandler OnCustomUp 2 TMGN_Brightness 7 again: // TMGN_Print offset len value bPadToLenWithZeros TMGN_Print 6 2 $second 2 TMGN_Print 4 2 $minute 1 TMGN_Print 2 2 $hour 1 goto again

Hello, your script is incomplete. You've forgot to include: Code: text Expand Select all Copy to clipboard TMGN_SetupButtons 100 required to setup button scan every 100ms. Buttons will not work without that.

Correct, I apologize for that, testing was intense and I missed that. Here is the correct script for testing that is working for me - build 1.17.48 Code: text Expand Select all Copy to clipboardstartDriver NTP ntp_timeZoneOfs +2:00 TMGN_Clear TMGN_SetupButtons 100 addEventHandler OnCustomDown 1 TMGN_Brightness 1 addEventHandler OnCustomUp 2 TMGN_Brightness 7 again: // TMGN_Print offset len value bPadToLenWithZeros TMGN_Print 6 2 $second 2 TMGN_Print 4 2 $minute 1 TMGN_Print 2 2 $hour 1 goto again

TM1638 seems to be fully supported now. TM1650 and HT16K33 are up next!

Hello, your script is incomplete.

You've forgot to include:
Code: text Expand Select all Copy to clipboard
TMGN_SetupButtons 100

required to setup button scan every 100ms.

Buttons will not work without that.

Topic summary

Development of the TM1638 driver is progressing, with updates on module integration and code functionality. The TM1638 operates with one segment per digit, differing from the TM1637's grid-based approach. Recent builds have introduced commands for clearing displays, printing values, and mapping functionalities. The driver now supports button event handling, allowing for actions on button presses. A complete script for testing has been shared, ensuring proper button setup and functionality. The TM1638 is reported to be fully supported, with plans to extend support to TM1650 and HT16K33 models next.
