Re: Detect errors in I2C readings

Hi @Roberthh, i'm reading the I2C protocol and now i see what you mean, so i'll have to study deeper the sensor datasheet to verify if it implements some errors correction code. But i still have a doubt, what happened if a NACK bit is transmitted by the master (esp32) during the execution of the met...

Internal filesystem with flash encryption

Hi, I've been able to implement flash encryption on esp32 with micropython firmware. The interpreter is working really well. I've also implemented my scripts as frozen modules with the micropython firmware. But now I'm having troubles with the internal filesystem. I've tried to create files using op...

Modbus library

Hello people, I'm starting an IoT project and I've decided to use the NodeMCU board. The project consists of remote monitoring of electrical grids, so then it is composed of a module which takes a lot of data from a power grid analyzer and then sends that to a remote server through the internet. I d...
