I have verified with an oscilloscope that there are bytes being sent on TX pin, flow control pins are switched as needed and there is response from the RS485 module of exactly 9 bytes present on the ...

The weird thing is that I attached my oscilloscope to the PDN_UART pin of the driver and this is what I see As you can see the ESP32 sends the data to the driver, the driver replies but the 0 bits of ...

There’s no substitute for a proper oscilloscope on your electronics bench. But unfortunately we still don’t have one of our own. But we’ve got an Arduino board and paired with ano… ...

Discover Bojan Jurca's open-source Arduino sketch "Esp32_oscilloscope," which converts ESP32 boards into web-based oscilloscopes accessible over WiFi. Learn about its compatibility, functionality, and ...

Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. Due to the size, ...

Got an Arduino board laying around? Make your own oscilloscope in only four steps. It might be the geekiest DIY project ever.

Arduino Mega board expands tracking time of an oscilloscope to a maximum of 12 hours, for example to display the (dis)charging curve of a battery.
