![]() ![]() I'm thinking this is either a dead/dying board or a firmware issue.ĭoes anyone have any suggestions? Can anyone point me to where to flash the nodemcu back to stock in the even that I somehow screwed that up? I found the cloud flash builder but I'm not sure what all needs included to flash it to it's original state. THere is nothing special to the wiring switching from D4 to D2. Tutorials online show D2 as being perfectly fine with nothing special in the code for this purpose. If I do that using D2 or 4 for the pin the script just acts like it's got nothing attached. OneWire lets you access 1-wire devices made by Maxim/Dallas, such as temperature sensors and ibutton secure memory. Written from scratch alternative for the classic Arduino OneWire library providing: (1) fixed handling of the 1-wire bus low-level activities related to its open-drain characteristic, (2) 1-wire touch support, (3) new I/O interface with enhanced parasite powering support, (4) advanced search filtering, (5) overdrive mode support, (6) Dallas ther. ![]() ![]() Specifically D2 is the one I'm wanting to make work. I can also use 2 as the sensor pin as D4 is just a mapping of gpio pin 2. I've made a simple script in arduino ide to read the temperatures from a one-wire ds18b20 using D4 as the sensor pin works just fine. Arduino library for the Maxim Integrated DS18B20 1-Wire temperature sensor. I've got a V1 NODEMCU it says Amica on the bottom. ![]()
