[BK7231T] Tuya switch with multiple buttons on single ADC pin

Question 1

Use the ADCButton driver and AB_Map to split the ADC range into three buckets. Bind OnADCButton events to your relay channels. Start the driver, set AB_Map 450 1250 2900, then add handlers that toggle the relays. This approach was validated by the developer. [Elektroda, p.kaczmarek2, post #20539846]

Question 2

Answer

In Configure Module, set P23 to ADC_Button.
In autoexec.bat: startDriver ADCButton, then AB_Map 450 1250 2900.
Add handlers: OnADCButton 0→toggleChannel 2, 1→toggleChannel 1, 2→toggleChannel 0. Adjust channel numbers if needed. [Elektroda, rishabmehta7, post #20541973]

Question 3

Measure raw counts, then set boundaries at midpoints between clusters. Example counts: 4095 (no press), 1604, 897, 2. Boundaries used: 450, 1250, 2900. These split the ADC space into three stable button zones. “Create margins between values (as average values).” [Elektroda, p.kaczmarek2, post #20539846]

Question 4

Create autoexec.bat via the Web Application under the LittleFS tab. Save the file there so it runs at boot. This is the supported method for persistent scripts and driver startup. [Elektroda, p.kaczmarek2, post #20539998]

Question 5

Update to the latest firmware. A fix adjusted behavior, so event indexes may differ from earlier builds. After updating, remap your OnADCButton handlers if necessary to match the observed indexes. [Elektroda, p.kaczmarek2, post #20541682]

Question 6

Verified mapping: P22 WiFiLed0, P24 Relay0, P07 Relay1, P08 Relay2, P23 ADC_Button5. This configuration, combined with AB_Map 450 1250 2900 and event handlers, delivered stable control. [Elektroda, rishabmehta7, post #20541973]

Question 7

Temporarily assign P23 to Temp to view raw ADC counts. Example readings observed: 4095 (no press), 1604, 897, 2 for buttons. Use these to compute midpoints for AB_Map. Revert P23 to ADC_Button after measuring. [Elektroda, rishabmehta7, post #20523046]

Question 8

Combined presses can yield blended counts like ~602, ~4, or ~3. Treat multi-press as an edge case and ignore or handle separately. Keep thresholds centered on single-press clusters to minimize false triggers. [Elektroda, rishabmehta7, post #20523046]

Question 9

No. You can place the ADC_Button on an unused channel, even channel 10. As the developer notes, “firmware will read ADC internally.” This keeps it separate from relay channels. [Elektroda, p.kaczmarek2, post #20541682]

Question 10

Yes. The user flashed with Cloud Cutter using a DS‑103 profile, then corrected pins manually. Once OpenBeken runs, configure the ADC and relays as described. This approach avoids soldering. [Elektroda, rishabmehta7, post #20523046]

Question 11

Yes, with proper thresholds and the ADCButton driver. The developer confirms it is “a known practice.” Use AB_Map midpoints and event handlers for stable control. Real hardware testing reported success. [Elektroda, p.kaczmarek2, post #20523162]

Question 12

A Tuya 3‑gang touch switch sourced as “WiFi Smart Light Switch Glass Panel” was referenced. The method applies to similar BK7231T boards that multiplex buttons on one ADC pin. [Elektroda, rishabmehta7, post #20534003]

Question 13

Pick boundaries at the average between measured clusters to add margin. For the shared ADC case, AB_Map 450 1250 2900 separated the zones cleanly. Re-measure after installation and tweak if needed. [Elektroda, p.kaczmarek2, post #20539846]
