HP41 TULIP4041 update

[Sylvain Cote]

The board was delivered last week and the final assembly was completed early this week.

My complete test setup is:

• host computer
  
  • Hardware
    
    • Raspberry Pi 4 Model B Rev 1.5 - 8GB RAM - Cortex-A72 with 4 cores (aka RP4B)
    • Armor Case Passive Cooling or Active Cooling
    • 128GB microSDXC SAMSUNG PRO Endurance
    • Raspberry Pi 15W USB-C Power Supply
    • Optional: mouse, keyboard and monitor. -> video: micro-HDMI-male_to_standard-HDMI-female_adapter and a standard-HDMI-male-male_cable
      
  • Software
    
    • Raspberry OS 64-bit → installed on microSD card with Raspberry Pi Imager
      OS: Debian GNU/Linux 12 (bookworm) | Kernel: Linux 6.6.31+rpt-rpi-v8 | Architecture: arm64
    • Special configuration:
      
      • default headless video set to 1280x1024
      • wired network static configuration for: IP, default gateway and DNS
      • default vnc server running
      • RealVNC client installed
        
  • Optional: Development & Debugging
    
    • Raspberry Pi Debug Probe
    • Raspberry Pi Pico development tools C/C++ SDK
      installation script
      
      Code:
      

      mkdir -p ~/temp
cd ~/temp
wget https://raw.githubusercontent.com/raspberrypi/pico-setup/master/pico_setup.sh
chmod +x pico_setup.sh
./pico_setup.sh
    • testing → follow instructions given in the Raspberry Pi Debug Probe documentation
      
      • install a Raspberry Pi Pico 1 (RP2040) on a breadboard
      • connect the Raspberry Pi Debug Probe to the Pico to the SWD connector
      • connect the Raspberry Pi Debug Probe to the Pico to the RP2040 GPIO RX/TX/GND pins
      • connect the Raspberry Pi Debug Probe to the USB port of the Raspberry Pi 4
      • compiled application files location
        
        • blink → ~/temp/pico/pico-examples/build_pico/blink
        • hello world serial → ~/temp/pico/pico-examples/build_pico/hello_world/serial
          
      • notes
        
        • OpenOCD, SWD, GPIO serial port and GDB works perfectly
        • I have tested several applications and did not find any issue
          
  • Virtual HP-IL
    
    • lifutils (utilities runs natively)
      installation steps
      
      Code:
      

      mkdir -p ~/temp
cd ~/temp
git clone https://github.com/bug400/lifutils.git
cd lifutils
mkdir rp4b
cmake -DCMAKE_BUILD_TYPE=Release -S . -B rp4b
cd rp4b
make
sudo make install
    • pyilper (application run natively, no virtual machine needed, well .... apart from cpython of course)
      installation steps
      
      Code:
      

      python3 -‑version                   // installed with the OS and I get version 3.11.2
python3 -m venv ~/py311
source ~/py311/bin/activate
python -m pip install --upgrade pip
pip install pyserial
pip install pyilper
      testing:
      
      
      1. connect PIL-Box to RP4B → serial port added: /dev/ttyUSB0
      2. start pyilper → from command line
         
         Code:
         

         source ~/py311/bin/activate
pyilper -‑clean -‑instance test
      3. configure pyilper to use /dev/ttyUSB0
      4. adds and configure virtual IL devices
      5. leave pyilper
      6. restart pyilper → from command line
         
         Code:
         

         source ~/py311/bin/activate
pyilper --instance test
      7. test virtual devices with an HP-41/71B/75
