Posted on July 03, 2018 at 09:38I have used CubeMX to generate the USB CDC driver. I connect my board to a PC and the device manager recognize it as: 'STMicroelectronics Virtual COM Port (COM1)', And then the device is connected.- STM32Cube V1.0 Ver...
Posted on July 03, 2018 at 00:09I want to know how can I aware about some gpio speed parmeters in Cube (low - medium -fast -high speed).For example I set cpu on 20Mhz and PinC.1 set as output push pull medium speed. In this state , what's the pin sp...
Posted on July 03, 2018 at 05:23Hi,What is the expected MCU power consumption / CPU state when calling HAL_Delay() from an ISR triggered while MCU is in STOP mode?
Posted on July 03, 2018 at 03:57i am using stm32l432kc MCU and EPCQ256 external flash, after the instruction phase and address phase is sent to the flash, ii want to make one gpio pin high before i start reading data from the flash. Is possible to b...
Posted on July 03, 2018 at 00:08I'm trying to build a simple 'hello world' program on the STM32H743 using the Makefile option and the standard Ubuntu arm-none-eabi-gcc V 4.9.3. At this stage my program doesn't even do floating point, but it will ev...
