Hi all, Although the title of this topic may sound simple, I cannot find a clear explanation on how this should work. A print() command in the MicroPyhton code can end up on several places: REPL, WebREPL, Tx/Rx pins. But how to prevent a print output to any of these locations? I'm a bit lost on this...

Just wanted to add my current exploration details to solve this problem. I found that the hardware SPI pins MISO and MOSI are 12 and 13, which seems to be a method of utilising the raw (potential) speed. Is it possible to provided bytes to a buffer directly and let the hardware deal with sending the...

Hi All, I'm trying to setup a four way communication, as a gateway, between two devices. I'm using an ESP8266 (Wemos D1 mini) with MicroPython 1.18. This device receives and forwards communication too and from the other devices. To be precise, the other two devices are OpenTherm devices, and I'm try...

Hi Roberthh, Thanks for the swift response, and for pointing to a solution. I wasn't aware that the espressif chips had this problem, too bad. Just one more question, is the 4N35 opto causing this slow/uncontrolled edge of the signal, or is the sensor already causing this? I tried looking via a mult...

Hi all, I was debugging my inductive proximity sensor code because the counter registers more revolutions than expected. My device is a Wemos D1 mini with the latest Micropython on it: "esp8266-20210418-v1.15", and the sensor is the DFRobot FIT0658, connected via a 4N35 optocoupler. I read that it i...
