Getting ili9488 TFT LCD working on Raspberry pi

If you are here, you likely have a ili9488 LCD and would like it going on the raspberry pi. We have been through the process of buying one of these modules and figuring it does not have native linux support and went ahead and wrote a driver for the same.

Our thanks to Noralf Tronnes for maintaining the excellent FBTFT repository and for his well documented code making it easy for us to write support for new hardware.

NOTE: Unfortunatley FBTFT is not taking in new drivers and all the modules are going to be supported via DRM ( Direct Rendering Manager ), so we could not deliver this patch upstream

We are writing up the process of building your own drivers and getting the ili9488 going on the Rasbperry Pi.

To be done before you get started:

- Have your raspberrypi setup with network connectivity

- PC ( Ubuntu/any other Linux distro) setup for cross-compiling Raspberry pi

- Have basic knowledge of compiling linux kernel

1. Find the kernel version running on the Raspberry Pi, its done as below


pi@raspberrypi:~/fbtft $ uname -r 
4.4.21+


2. Download the same kernel version from Raspberry pi linux repository 

On your PC

PC:$ git clone --depth=1 -b rpi-4.4.y https://github.com/raspberrypi/linux 


3. Download this patch and patch it onto the linux tree which we just cloned from the Raspberry pi Repository

Download this file and save it into file named ili9488.patch


PC:$ cd linux/


Save the file ili9488.patch into the linux directory and apply the patch to the linux repository


PC:$ patch -p1 < ili9488.patch patching file drivers/staging/fbtft/Kconfig

patching file drivers/staging/fbtft/Makefile

patching file drivers/staging/fbtft/fb_ili9488.c

patching file drivers/staging/fbtft/fbtft_device.c

4. Get the linux configs from your raspberrypi so we can build the kernel modules with same configuration

Run below commands on your raspberry pi

pi@raspberrypi:$sudo modprobe configs

pi@raspberrypi:$zcat /proc/config.gz > .config


Copy the .config file to your linux folder on your PC

5. Start building (ref : Raspberrypi Kernel Build )

 For Pi 1 or Compute Module:

cd linux KERNEL=kernel make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcmrpi_defconfig

For Pi 2/3:

cd linux KERNEL=kernel7 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcm2709_defconfig 

Then, for both:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules 
NOTE: To speed up compilation us the -j n options along with the above command where n is the number of processors * 1.5
ex: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs j=6
6. Copy the kernel module driver to the raspberry pi 

If the build goes through well, you would have the fbtft modules compiled, lets copy them to your Raspbery pi.
Note: All our fbtft driver are in the folder drivers/staging/fbtft
PC:$scp -r drivers/staging/fbtft pi@raspberrypi.local:~/

7. Load the drivers to the Raspberry pi
pi@raspberrypi:~/fbtft $ sudo dmesg -C
pi@raspberrypi:~/fbtft $ sudo modprobe fbtft
pi@raspberrypi:~/fbtft $ sudo insmod fb_ili9488.ko 
pi@raspberrypi:~/fbtft $ sudo insmod fbtft_device.ko name=mcufriend_ili9488 debug=3
At this point the LCD display should turn black, That would mean the driver has initialized and its all set to go

8. Testing the display works

pi@raspberrypi:~/img $ sudo apt-get install fbi

pi@raspberrypi:~/img $wget http://www.vanessadewson.com/wp-content/uploads//galleries/post-1747/ful...-O nature.jpg

pi@raspberrypi:~/img $ sudo fbi -d /dev/fb1 -T 1 -noverbose -a  nature.jpg

You should see the image popping up on the display.
Have fun...

Wifi Datalogger and monitoring system

Description: 

Industrial and commercial projects need constant monitoring of sensors and collection of data in a format which is readily accesible and can be visualized with ease. For solving this problem we have developed a Datalogger and monitoring system which works over Wifi.

  The beauty of this system is its entirely self suficient, Does not need an existing wireless network. It simply creates its own Wifi access point and
the you can connect to it simply with a PC, android or Iphone.


What does this mean:

This means the user is able to monitor the temperature sensors connected to the datalogger in these simple steps

1. Smart phone (iphone, android ) or your PC sees "DATALOGGER" wifi network, simply connect to it.

2. Download the logged data in the format of Excel readable CSV files

3. See live graphs by clicking following this URL.



This device can be used for monitoring temperature for soil, industrial monitoring systems, vineyards etc. We do provide support to add different type of sensors to cater for other datalogging uses.


What comes with the purchase:

  • Datalogger
  • 2 x Temperature sensors (water proof,  -25 - 125 DegC range)
  • 5v Power adapter


FAQ:

1. Can this Datalogger connect to other sensors other than the ones which comes with it ?

A. Yes, we already have support for K type thermocouples ( works upto 500 Deg C ) as well as others, just contact us and post your needs we can get it working for you.


2. Will this sensor work in places with no Wifi coverage?

A. Yes, Since this device creates its own Wifi network, it can work in areas where there is no wifi coverage.


3. How does the graph look like?

A. The graphs would have the same look and feel as this one ( NOTE: For the datalogger the data would be 2 Temperature series lines )

4. Can I see a sample of the Excel readable file which the datalogger creates?

A. This sample CSV file was created by the logger. You can download it and view it in Excel. ( or openOffice )


3. Can I get you to add more temperature sensors of the same type to this logger ?

A. The standard package comes with 2 Temp sensors ( -25 - 125 DegC range),  for sure we can add more sensors to the Logger for a small cost.


4. Does this device need any assembling or is this a plug and play device ?

A. This is a plug and play device with no assembling required. You just have to power it and it should just work out of the box.


5. How do I view the graphs once the Datalogger is powered up ?

A. From your Mobile/PC connect to the Wifi network called 'DATALOGGER'. Once connected you can view the graphs by

Wireless Sensor and Data Logger

Description: 

What can this box do?

This kit takes measurement of its two precision temperature sensors, and logs the data to a SD card. Both real time readings and stored data can be sent wirelessly to a PC.

How is it useful?

One of the two temperature sensors is located inside the box, and the other one outside on a 1.2 meter cable. By locating the two temperature sensors in two different areas (e.g. indoor and under floor). We can see the temperature variations of the two areas over time. One good use case is to measure how good your home insulation is. Having said that, this kit is designed with DIY in mind. Extra sensors can be added very easily, and soldering is minimum because of the use of the sensor shield. By adding a humidity sensor, light sensor, wind speed sensor etc, this box can be turned into a wireless weather station!

What is included in this kit?

This wireless sensor and data logger kit embodies a few very cool technologies: Real Time Clock, SD Card read/write, Bluetooth and one wire digital temperature sensor. Not only can it be easily turned into a general purpose wireless sensor logger, it also is a fantastic educational kit after all. This kit includes all the neccessary bits to construct a fully working wireless sensor logger, the package includes:

  • Arduino Mega 2560
  • Arduino Mega sensor and servo shield
  • USB cable
  • Real Time Clock module (onboard temperature sensor incl.)
  • SD card module
  • Kingston SD Card 1 GB
  • Bluetooth module
  • Temperature sensor
  • Waterproof case
  • Cable gland x 2
  • Some wires and accessories
