WideUSB

Board based on STM32F4 to connect various perepherial over USB. May be useful with single-board computers (SoCs) like Raspberry Pi

Nearest roadmap and tasks

• Base

  • Check that RingBuffer is thread-safe
  • Something for errors reporting
  • Global error handler and other callbacks - define something understandable

• Networking

  • Retransmitting to another network devices (works on PC simulation)
  • TimePlanner should return time of next activity
  • Internal transmission without network
  • Struct-based layers parameters
  • Send ack second time if already sended ?
  • Move base64 to communication

• STM32 Hardware abstraction

  • Devices driver structure: Driver <- Hal driver <- instance with concrete handlers configured by Cube
  • Some kind of RTOS-based light asio analog

• Device core

  • All time-related -> std::chrono
  • Change debug printf to something without malloc https://stackoverflow.com/questions/262439/create-a-wrapper-function-for-malloc-and-free-in-c

• Modules interface

  • For each module make 'module back' and 'module front'. Front should be avaliable from MCU too.
  • Change folders structure for modules
  • Derive backs from IModule

• Monitor module

  • Run new stack on board
  • Merge to master: remove old code and files

• GPS module

  • Fill thimestamp structs with content

• Asynchronous C++ API

  • Add timeout for operations

• Synchronous python API

  • Replace condition variable with promise/future and wait_for (No! Timeout shoud be made in another way!) ...

• DAC module

• ADC module

• GPIO module

• nfr24l01 device

  • Driver abstraction
  • Driver implementation
  • Single device test
  • Double device test
  • Device class code refactoring
    • SPI without IRQ

• LoRa module

  • Double device test
  • Code refactoring and adaptation
    • Adapt as a class
    • Make physical layer

• State saving in EEPROM

• IR transmitter

• IR receiver

Hardware

• Gen 1 PCB design

Bugs

• [?] CRITICAL: LoRa works only if message len > real sending amount - stabilisation with timouts
• IMPORTANT: sometimes MCU spam inconsistent messages instead of replying by USB. Disabling lock glue fixes the problem... fixed by disabling malloc/free wrappers (NOT FIXED!..)
• Wrong parameters value: file /home/dalexies/Projects/wideusb/source/stm32/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_hal_cortex.c on line 171 during HAL_NVIC_SetPriority in HAL_InitTick from HAL_InitTick (uwTickPrio); (stm32f4xx_hal_rcc.c:724) where uwTickPrio is set at uint32_t uwTickPrio = (1UL << __NVIC_PRIO_BITS); /* Invalid PRIO */ - this is generated by Cube
• malloc(): mismatching next->prev_size (unsorted) on python exit
