Arduino Based Test Station

Hardware

• BLACK-PILL-HUB - Test Station Processing element
  • STM32 Black Pill - CPU card
    • Preferred choice due to nearly unlimited resources
  • Previous CPU choices
    • BLUE-PILL-HUB
      • FTDI card required
    • NANO-BKOUT
• DIGIO32-I2C - 32-bits of Digital I/O for testing some cards
• LED-32 - 32 LEDS for bounce across LEDs tests
• DB37RIBBON - DB-37 Male to right angle Ribbon cable header
  • DB-37 plugs into Test Station DIGIO32-I2C
  • Some UUT cards use a second DB37RIBBON card
• DB25RIBBON - DB-25 Male or Female to Ribbon cable
  • Some UUT cards have DB-25 connectors
• UUT cable sets
  • Connect to DB37RIBBON, DB25RIBBON, or LED-32 cards in Test Station
• PC running PuTTY
  • 9600 baud
  • USB-C cable
    • USB connected to PC and USB-C connected to BLACK-PILL-HUB
• Powered through the USB-C connector on the STM32 Black Pill

Personality EEPROM

• Tests cards without personality EEPROM
• Tests cards with personality EEPROM
  • Personality EEPROM follows Raspberry Pi Hat EEPROM format
  • Test station writes EEPROM
  • Test station uses EEPROM contents (if present) to determine which test to run

Example Personality EEPROM - DIGIO-128

Black Pill Setup

Resources

• Plenty of resources
  • EEPROM - 524288 bytes
  • SRAM - 131072 bytes

Sketch uses 50316 bytes (9%) of program storage space. Maximum is 524288 bytes.
Global variables use 3828 bytes (2%) of dynamic memory, leaving 127244 bytes for local variables. Maximum is 131072 bytes.

Programming

Programming Setup

• Steps from Programming|Program STM32 Black Pill (STM32F401 / F411) with Arduino IDE (Windows OS)
  • Add the URL to Additional Board Manager URLs text box:
    • https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json
  • Go to Tools > Board > Boards Manager
  • Search for STM32, select latest version and click Install.
  • Download and install STM32CubeProg from ST.com: [1]

DFU Programming

• • Start the STM32CubeProg
  • From the Tools > Board > STM32 Board, select Generic STM32F4 series
  • Select Tools > Board Part Number > BlackPill F411CE
  • Under USB Support, select CDC (generic "Serial" supersede U(S)ART)
  • Under Upload method, select SMT32CubeProgrammer(DFU)
  • Use the onboard BOOT0 and NRST button to put the board into bootloader mode:
    • press and hold the BOOT0 button
    • press and release NRST (reset) button to power cycle the processor
      • alternate is to press the Reset button on the BLACK-PILL-HUB card
    • release BOOT0 button
    • Sometimes removing the USB cable and plugging it back in while pressing BOOT0 button works better
  • Upload sketch

• Displays in IDE
