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 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_USART1 to TRUE

NOTE: this configuration was successfully tested in an ST_STM32F769I_DISCOVERY board using the Serial port through the onboard 7ST Link USB connection.

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.
