In a previous article, I released a GUI for libnfs library.

This time, I’ll release a command line tool allowing one to perform simple tasks against NFS exports.

nfsclient 0.1 by erwan2212@gmail.com
nfsclient 0.1 discover
nfsclient 0.1 read nfs://server/export/filename
nfsclient 0.1 write nfs://server/export/ local_filename
nfsclient 0.1 dir nfs://server/export/

Lately I have discovered libnfs.
I quote « LIBNFS is a client library for accessing NFS shares over a network. ».

It is well documented and easy to use with Delphi (or freepascal).

I have decided to build a lightweight NFS client with simple features : discover, list directories, read & write files.

That could be handy at some point with either CloneDisk or TinyPXE Server.

In previous article, we have seen how to flash an ESP8266 with ESPEasy.

Lets now see how easy it is to use a sensor such as a DHT11 temperature/humidity sensor.

Lets wire 3v3 and ground and data to our esp8266 gpio 0.

Now, simply add a device on port GPIO 0 and pick a type « Environment – DHT11/12/22 ».

And your ESPEasy should now report temperature and humidity.

I had this old esp-01 standing on my desk for a while and decided to dust it out by flashing Espeasy firmware.
About this esp8266, see previous articles here.

Note that if you are not sure which esp8266 you model you have, check it out here.

Before we flash, lets do some simple wiring :
-wire 3v3 and ground.
-wire tx to rx, and rx to tx (I use a usb to serial ftdi adapter)
-set gpio0 to low (ground)
-set ch_pd (also referred to en) to high (3v3)
-power off/on to enter flash mode

It is as simple as put your firmware next to flashesp8266.exe (in my case firmware is ESPEasy_mega-20180102_normal_ESP8266_1024.bin) and execute ESPEasy Flasher.

Once flash is completed, set gpio0 free (but leave ch_pd high), power off/on and you should see a new ssid on your network called esp_easy_0 (password=configesp).
configure it i.e connect it to your wireless network and you are done.
