Configuration of ChibiOS, HAL and MCU

For a successful build the following changes are required:

For memory maps, uuid etc. the reference document used was: http://www.st.com/content/ccc/resource/technical/document/reference_manual/group0/96/8b/0d/ec/16/22/43/71/DM00224583/files/DM00224583.pdf/jcr:content/translations/en.DM00224583.pdf

In halconf.g (in both nanoBooter and nanoCLR folders), when compared with a default file available from (https://github.com/ChibiOS/ChibiOS/tree/master/demos/STM32/RT-STM32F769I-DISCOVERY):

  • HAL_USE_SERIAL_USB to TRUE
  • HAL_USE_USB to TRUE
  • SERIAL_DEFAULT_BITRATE to 921600

In mcuconf.h (in both nanoBooter and nanoCLR folders), when compared with a default file available from (https://github.com/ChibiOS/ChibiOS/tree/master/demos/STM32/RT-STM32F769I-DISCOVERY):

  • STM32_SERIAL_USE_USART2 to TRUE
  • STM32_USB_USE_OTG1 to TRUE

NOTE: this configuration was successfully tested in an ST_STM32F769I_DISCOVERY board using the Serial over USB connection on USB port 1 that creates a virtual COM port.

ADC configurations

The following ADC channels (and respective GPIO pins) are available to the managed API, in the respective index:

  • PA6, ADC1 IN6
  • PA4 ADC1 IN4
  • PC2 ADC1 IN12
  • PF10 ADC1 IN8
  • PF8 ADC3 IN6
  • PB8 ADC3 IN7
  • Temp Sensor ADC1
  • VrefInt ADC1
  • Vbatt ADC1

Floating point

The current build is set to add support for single-precision floating point. Meaning that System.Math API supports only the float overloads. The double ones will throw a NotImplementedException.
