Using ESP-01 for conversion of Glediator to WS8212B
Posted: Sat Apr 20, 2019 11:54 pmI have very good experience using different Arduinos for the conversion of Glediator serial stream to control LED-matrix WS8212B. But when I replace the Arduino with ESP-01, it is not working. The ESP-01 can control the WS8212B-strip, if I upload a sketch with ready made sequences, so the issue is not hardware (3V to 5V etc.) I believe the problem is timing. The ESP-01 has to receive the serial stream while it is sending the pulses to the LED-strip, which is very time sensitive. Probably the serial interrupt works differently in Arduino and in ESP-01. So here I am asking if anyone has (successfully) used the ESP-01 for this purpose or maybe for WiFi communication instead of serial.
