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 

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

On your PC

PC:$ git clone --depth=1 -b rpi-4.4.y 

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 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...

InfraEye: Thermal imaging kit


The visible spectrum is that part of the electromagnetic spectrum which our eyes can see, It can see light of wavelengths 390 to 700nm.

The long infrared window (wavelength 9 - 14 um) lies outside the range of human vision, There are fascinating applications when one can can see the infrared. This kit allows you to do just that.

All objects emit infrared radiation according to the black body radiation law, using this thermal cameras can see without the need of visible illumination. The applications of thermal imaging span many areas from medical, night vision to checking home insulation and finding sources of heat leakage.

Below is the sample image created using the kit of a heated oven. One can clearly see the hottest part of the oven as well as see the heat escaping from the oven to the surroundings.

How the kit works:

The kit uses a very sensitive contactless temperature sensor which measures temperature without contact. Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted.

 This sensor can provide the temperature of one point, But to construct an thermal image we need many readings from different points. This is accomplished by having the sensor scan the area of interest and taking readings and using the data to construct the image.

The scanning is done using 2 axis gimbal which is rotated using X and Y axis servos, the scanner with the thermal camera is as shown below:

This application is responsible for collecting the data sent from the temperature sensor via the Arduino and creates a visual Thermal image.

Below is the image created by the InfraEye therma viewer when it scanned the heat dissipated by a LCD tv.

The kit set comes with all the bits you need to construct the InfraEye Thermal viewer and accompaniying Java application and Arduino source code.

This kit is a great learning experience and a source of endless fun.

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 ?

Wireless Sensor and Data Logger


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 wirless 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.
