Working of the Sense HAT LED Matrix

The LED Matrix on the Sense Hat is driven by the led2472g IC which is a LED driver manufactured by STMicroelectronics. This LED driver is controlled by ATTiny88. The ATTiny88 acts as a slave on the IIC bus and can be accessed at 0x46 slave address.

The Sense HAT python API uses 8 bit (0 to 255) colors for R, G and B components of a pixel. When these values are written to the Linux frame buffer they're bit shifted into RGB 5 6 5. The driver converts them to RGB 5 5 5 before it passes them to the ATTiny88 AVR for writing to the LEDs.

VIVADO Block Design

The VIVADO Block design can also be created from the given Tcl Source[Link], you can create the VIVADO block design by sourcing it on VIVADO Tcl console. The Block design will have Zynq MPSoC PS, AXI IIC IP, GPIO, Interrupt Controller and other necessary IP blocks. This VIVADO block design will be used for "Interfacing SenseHAT's Sensors + LEDMatrix and Joystick" on this tutorial.

Note: In this block design we have AXI GPIO is used for "handling interrupt of LEDMatrix and Joystick". This AXI GPIO block was not there at Part-II (LEDMatrix), along with AXI GPIO block we will also have to assign contraint for it in this tutorial.

Functions of the used IP Cores/Block's are listed below.

• The clocking wizard is used to generate a single 100 MHz clock for all the peripherals. It receives both the clock and reset inputs from the PS.
• The concat block is used to group all the interrupts in the system together. The input to this block are interrupts from other blocks such as the IIC and the GPIO block. The concat block will present all these interrupts on a single bus as its output which is connected to the interrupt input of the PS.
• The processing system reset block provides the reset signal to all the peripherals.
• The AXI interconnect manages all the AXI peripherals and this provides a master interface for the peripherals.
• The interrupt controller handles all the interrupts connected to its input.
• The IIC block acts as an I2C master and controls all the sensors and devices attached to the I2C bus.
• The GPIO block handles the interrupt generated by the Sense HAT on pin 16 of the RPi header.

Sense HAT - KR260 Header Alignment

The Sense HAT sits over the RPi header on the KR260 as shown in the picture above. The description of the 40 pins is shown for this alignment. The sensors communicate over I2C which uses pins 3 and 5.

Constrainting

Only 2 pins (AE14 and AE15) on the KR260 require constraining for I2C to work. AE15 is used for SDA and AE14 is used for SCL.

# RPi IIC
set_property PACKAGE_PIN AE15 [get_ports {iic_sda_io}]
set_property IOSTANDARD LVCMOS33 [get_ports {iic_sda_io}]
set_property PULLUP true [get_ports {iic_sda_io}]

set_property PACKAGE_PIN AE14 [get_ports {iic_scl_io}]
set_property IOSTANDARD LVCMOS33 [get_ports {iic_scl_io}]
set_property PULLUP true [get_ports {iic_scl_io}]

# Interrupt
set_property PACKAGE_PIN AA12 [get_ports {rpi_irpt_tri_i}]
set_property IOSTANDARD LVCMOS33 [get_ports {rpi_irpt_tri_i}]

However, the following image can be used as a reference to map and constrain all other pins.

Generating XSA

• From the File menu on VIVADO tool, select Export > Export Platform.
• Select the Hardware option in the Platform Type window.
• Select the Pre-Synthesis state and also select the Include bitstream option in the Platform State window.
• Change required Platform Properties.
• Enter a name for the XSA and select a folder to export the XSA to and select Finish.

Accelerometer/Gyroscope and Magnetometer

• https://github.com/STMicroelectronics/lsm9ds1-pid

Pressure/Temperature

• https://github.com/jbroutier/LED2472G-driver

Petalinux Project- Prerequisites

Creating a petalinux project requires a supported BSP which can be downloaded from the link below. A project also can be created without the BSP which is less convenient.

• Download the KR260-SenseHAT BSP from: https://github.com/LogicTronix/KR260-SenseHAT-Petalinux/tree/KR260-SenseHAT-Final/design_files
• This provided BSP already has configured the necessary packages and drivers, so it can be directly build. Or you can update the "Hardware on this BSP" using Get-Hardware-Config command of Petalinux.

Create Petalinux Project with provided BSP and Build it:

petalinux-create --type project -s <location-to-bsp> --name <project-name>
cd  <project-name>
petalinux-build

• On this provided BSP, we have included "KR260 App in the RootFS", so the Kria App automatically loads while booting on the KR260-Board.
• We also have added SenseHAT drivers by creating "recipes-modules" on this BSP file itself. Further details of the "SenseHAT" drivers can be found at: https://github.com/LogicTronix/KR260-SenseHAT-Petalinux/tree/KR260-SenseHAT-LedMatrix/driver
• So "petalinux-build" basically did all config and build the petalinux project.

Generating/Creating a Bootable Image

Run the following command to create a bootable WIC image.

petalinux-package --wic --images-dir images/linux/ --bootfiles "ramdisk.cpio.gz.u-boot, boot.scr, Image, system.dtb, system-zynqmp-sck-kr-g-revB.dtb" --disk-name "sda"

• Make sure the dtb file is present in the <petalinux-project-dir>/images/linux/ directory.

• Burn the SD card with the WIC image, and boot up the KR260 board (with SenseHAT).
• On this WIC image, the "kr260 overlay" is automatically added on "RootFS of WIC image", the BSP have that configuration. So this step sort-out(remove) steps like "copying dtbo, bit.bin and shell.json" into Board(/lib/firmware/xilinx/) manually.

[Alternative of WIC Image]- Download

You can download the SD Image from following Google Drive [Link], you can boot the KR260 with this WIC image, clone the git repo and run the main.py application.

Loading the Overlay and Detecting Devices on the I2C Bus

List the apps present on the device.

sudo xmutil listapps

Unload the current app.

sudo xmutil unloadapp

Load your app (kr260 in this case).

sudo xmutil loadapp kr260

Check if the XIIC is listed as an I2C bus in the system.

i2cdetect -l

• This will list all the I2C bus in the system (i2c-7 in this case).
• If the bus is unavailable, unload and load the app again.

Check for devices on the XIIC bus.

• sudo i2cdetect -y -r <i2c-bus-number>
• This will show the address of the sensors connected to the I2C bus.
• If the Sense Hat is working, it should show the following addresses.
• The following address map of I2C bus 7 shows all the sensor addresses from the Sense HAT. These addresses are also listed in table 1.

• Make the bus accessible to your user group by running the following command.
• sudo chown root:petalinux /dev/i2c-<bus_number> && sudo chmod g+rw /dev/i2c-<bus_number>
• e.g. sudo chown root:petalinux /dev/i2c-7 && sudo chmod g+rwx /dev/i2c-7

Prerequisites for running the main.py script

To communicate with the sensors attached to the bus with python, a python package needs to be installed.

Installing SMBus

To install SMBus, run pip3 install smbus. SMBus provides python bindings for Linux SMBus access through i2c-dev.

SenseHAT Package [Cloning it on KR260 Board]

The Main.py python script

The main.py [https://github.com/LogicTronix/KR260-SenseHAT-Petalinux/blob/KR260-SenseHAT-Final/main.py] is an example script provided for convenience. When the user runs this script, a ‘Hello World’ message is displayed over the LED matrix. The joystick can then be used to toggle between and display various readings from the temperature, humidity, pressure, accelerometer, gyroscope and magnetometer sensors.

It takes time to display long messages on the LED matrix. So longer texts are sent to the stdout instead. So watch over the terminal for messages.

To run the main.py script, run:

python3 main.py or python main.py on the terminal.

The program keeps displaying the ‘Hello World!’ message until the user uses the joystick. While the message is being displayed over the LED matrix, the program waits for user input in a separate thread. This thread updates what function to execute based on the joystick movement. The five buttons on the joystick are mapped to functions listed below.

● Up - Humidity

● Down - Pressure

● Left - Accelerometer

● Right - Gyroscope

● Middle - Temperature

The color on the display switches to a random color on every press of the joystick.

The example directory in the Logictronix Git repo has other scripts that you can try. The Readme file on the repo also has some basic examples. You can also check https://pythonhosted.org/sense-hat/api/for detailed description of the methods. Note that not all methods and properties listed in https://pythonhosted.org/sense-hat/api/ are available. Supported methods and properties are listed in the repos readme file.

If you would like to print other information to the terminal, you can use the available methods and properties listed in the repo’s readme with a python print statement. However, if you need to display the information on the matrix, convert the output from the method or property to string using the builtin python str method.

Drivers

Most HATs that require drivers will probably already have drivers in the upstream Raspberry Pi linux repo. If the board is relatively new, the manufacturer of the board could provide the drivers for it. Get the drivers from the upstream repo or any other source and add it to the petalinux roofs. The steps are described in the “Adding Sense HAT Driver in the rootfs” section of this document.

Interrupts

Some devices on these HATs make use of the interrupt, like the joystick on the Sense HAT. If the device is not functioning properly, you might want to check if the HAT uses interrupts on the datasheet or the schematic. When the system is interrupted, an interrupt service routine is executed to handle that interrupt.

To connect the interrupt to the PS, you can use the GPIO block and tie its interrupt output to the interrupt controller or the PS interrupt input. If there are multiple interrupts in the system, use a concat block to join all interrupts and connect the output of the concat block to the PS interrupt input.

The Sense HAT uses pin 16 on the RPi header as the interrupt pin.

Device Tree

Simply adding the drivers in the root file system won’t make the device work. It will also require modification to the dts ot dtsi file. These files describe the hardware that cannot be dynamically detected.

rpi-sense@46 {
#address-cells = <0x01>;
#size-cells = <0x00>;
compatible = "rpi,rpi-sense";
reg = <0x46>;
keys-int-gpios = <&axi_gpio_0 0 4>;
status = "okay";
};

For example,

● The compatible property in the above node is used to bind the device with the specified driver.

● The #address-cells property indicates how many cells are needed to form the base address part in the reg property.

● The keys-int-gpios property tells the interrupt is handled by axi_gpio_0 interrupt controller and is connected to pin 0 and is LEVEL_HIGH triggered.
