DIGIO32-I2C

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

Useful Arduino Code

Here's some useful pieces of Arduino code

Wait for Host Serial to Connect

  Serial.begin(9600);
  while (!Serial);    // wait for serial port to connect. Needed for native USB

uint8_t checkI2CAddr(uint8_t addr)

Check if there is an I2C device at an address

////////////////////////////////////////////////////////////////////////////
// uint8_t checkI2CAddr(uint8_t addr) - Check that an I2C device is present
// Pass: addr - I2C address
// Returns:
//      0 : success
//      1 : data too long to fit in transmit buffer
//      2 : received NACK on transmit of address
//      3 : received NACK on transmit of data
//      4 : other error
////////////////////////////////////////////////////////////////////////////

uint8_t checkI2CAddr(uint8_t addr)
{
  Wire.beginTransmission(addr);
  return (Wire.endTransmission());
}

uint8_t checkIfMCP23017(uint8_t addr)

Check if an I2C device is an MCP23017 at an address

////////////////////////////////////////////////////////////////////////////
//  uint8_t checkIfMCP23017(uint8_t addr)
//  Check to see if the I2C part is a MCP23017
//    The GPU Pullup A register (internal register address 0x0c) is present
//    in a MCP23017 but not in a MCP23008.
//  Pass: addr - I2C address
//  Returns
//    0 : Not an MCP23017
//    1 : Likely an MCP23017
////////////////////////////////////////////////////////////////////////////

uint8_t checkIfMCP23017(uint8_t addr)
{
  // Write 0x55 to MCP23017_GPPUA (0x0c)
  Wire.beginTransmission(addr);
  Wire.write(0x0c);
  Wire.write(0x55);
  Wire.endTransmission(1);
  // Read back
  Wire.beginTransmission(addr);
  Wire.write(0x0c);
  Wire.endTransmission();
  Wire.requestFrom(addr,  1);
  if (Wire.read() == 0x55)
  {
    Serial.println(F("Detected MCP23017"));
    return 1;
  }
  else
  {
    Serial.println(F("Detected MCP23008"));
    return 0;
  }
}
