A ST Micro STM32429I-EVAL Board Peripheral List

The following ADC channels are pre-configured.

Additional notes:

• Potentiometer (RV1) is connected to ADC3 channel 8 via GPIO PF10

• For the sampling interval, only a limited set of values are supported: 11810, 14857, or 46857 usec. Setting the sampling interval to any other value will force it to be reset to the closest legal value.

• After a call to ADCChannel.startMonitoring(), a MonitoringListener cannot be called more than one time around the boundary because of jitter.

• Note the following conditions on ADCChannelConfig parameters: the resolution is a 12-bit fixed value regardless of the input parameter, and the sampling interval and the sampling time are the same internally. PERIPHERAL_CONFIG_DEFAULT is supported, and the default value is 46857 usec.

The following GPIO pins are pre-configured:

Additional notes:

• If the controllerNumber is set as GPIOPinConfig.DEFAULT, it is interpreted as 6. The pinNumber in this case is 6 as well, this a GPIOPin connected to the Green LED will be opened by default.

• If the mode is set as GPIOPinConfig.DEFAULT and direction is set as INPUT then the default mode is interpreted as MODE_INPUT_PULL_DOWN. If the direction is set as OUTPUT, then the default mode is interpreted as MODE_OUTPUT_OPEN_DRAIN.

• The following GPIO pins cannot be opened because they are mapped to other resources. For more information, refer to evaluation board schematics from ST Micro.

  • SPI bus: PF9, PF8, PF7, PF6

  • ADC: PF10

  • UART: PA9, PA10

  • SDHC: PC8, PC9, PC10, PC11, PD2

  • I2C: PB6, PB9

  • Ethenet: PC3, PG13, PG14, PC2, PB8, PG11, PA1, PC4, PC5, PH6, PH7, PA7, PB10, PA3

  • JTAG/SWO: PA13, PA14

  • USB (OTG-HS): PB0, PB1, PB5, PB10 ~ PB13, PA3, PI11

  • LCD: PJ0 ~ PJ15, PK0~PK15, PI12~PI15

  • FMC: PF0 ~ PF5, PF11 ~ PF15, PG0 ~PG5, PH8~PH15, PI0~PI3, PI9, PE0, PE1

  • SDRAM: PH5, PG15, PF11, PH3, PH2, PG8

• Onboard LEDs are connected with their anodes to 3v3. To turn them on, set the pin to false.

The following GPIO ports are pre-configured:

Additional notes:

• The following GPIO ports are supported: PA, PB, PC, PD, PE, PF, PG, PH, PI, PK

The following I2C devices are pre-configured:

The following additional hardware information is applicable for I2C devices:

• The CMSIS I2C driver on this board only supports the following two types of clock frequencies: 100kHz (ARM_I2C_BUS_SPEED_STANDARD), and 400kHz (ARM_I2C_BUS_SPEED_FAST).

• I2C1 controller information: I2C1_SCL maps to PB6, and I2C1_SDA maps to PB9. The address capability is 7-bit only, the addresses used are 0x32 (on-board Audio) and 0x42 (on-board IO Expander), and the clock frequency is either 100 KHz (standard speed) or 400 KHz (fast speed).

The following additional information is applicable for I2C devices on the board itself:

• For the IO Expander: the device is STMPE1600, which is a GPIO port expander that is able to interface a main digital ASIC(MCU) via the two-line bidirectional bus (I2C). The connected MCU's I2C Controller is: I2C1; applicable pins are I2C1_SCL : PB6, I2C1_SDA : PB9, and IO_EXPANDER_INT : PI8 (the IO Expander interrupt pin is connected to the MCU). The clock frequency may be between: 0 and 400 kHz.

• Joystick: Remember that the pins are not connected to MCU, but are instead connected to the IO Expander. By reading and writing the registers of the IO Expander, the joystick status can be monitored. Out of 16 pins of IO Expander, the following 5 pins are connected to the joystick: EXP_IO14: SELECT; EXP_IO13: DOWN; EXP_IO12: LEFT; EXP_IO11: RIGHT; EXP_IO10: UP.

SPI is currently supported, however there are no pre-configured SPI devices on the board. However, the board is able to connect an external module to the pinout on the board as a ad-hoc device, as follows.

• SPI5 is the only connection supported, so the controllerNumber should be 5. This is default value. Use the following SPI pins: MOSI: PF9; MOSI: PF8; CLK: PF7; CS: PF6.

• CS is available only as 'active low'

• According to the ST Micro documentation, SPI5 can communicate at up to 45 Mbits/s.

• The following are default parameters:

  • controllerNumber : 5

  • address: 0

  • clockFrequency : 10000000 (10 MHz)

  • wordLength : 8 bits

  • bitOrdering : Big Endian

  • csActive : ACTIVE_LOW

  • clockMode : CPOL-High , CPHA-Even

The following UART devices are pre-configured:

Note the following.

• Supported UART: USART1 at onboard hardware connector CN8.

• Hardware setting: jumper JP7 should be set to 1-2 (default setting)

• Supported parity: none, even and odd. mark and space are not supported

• Supported databit: 5, 6, 7, 8 and 9

• Supported stopbit: 1, 1_5 and 2

• Hardware flow control is not supported

• Log channel note: UART logging is disabled by default. If the internal property log.method is set to UART, then USART1 is dedicated to logging and you cannot use USART1 as the Device I/O UART

• The following are default parameters:

  • baudrate: 115200

  • parity: none

  • databit: 8

  • stopbit: 1

  • flow control: none

The following watchdog devices are pre-configured:

• Note that the platform watchdog is not a DIO watchdog for Java application. Instead, it's the platform's general watchdog.

• The system.watchdog property must be enabled. This is an internal property for platform watchdog in the jwc_prop.ini file. Note that the default value is false.

• The timeout value is 4 seconds, which means the device will reboot if it is frozen for more than 4 seconds.
