Posted on July 01, 2018 at 19:20Hi All, Having got the USART working, and being able to exchanged data via the serial port I want to try and drive an Adafriuit IIC backpack. This uses the Holtek HT16K33 driver chip.I have connected the backpack's SC...
Posted on July 03, 2018 at 13:11I 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 June 29, 2018 at 03:03I am using the STM32F091. I have been trying to use the ADC with DMA in circular mode writing to a large array for use as a sort of double buffer by shifting the first half of the values out on the half transfer compl...
Posted on April 21, 2017 at 12:03Hi everyone,I'm developing a firmware in which a IR communication protocol is designed. The uC is a STM32F042C6 and I'm using HAL drivers.The protocol should work as follow (infinite loop):1> Receive 1 byte in interr...
Posted on July 02, 2018 at 22:38Hello, I'm trying to measure the ambient temperature using the nucleo l432kc internal temp sensor . I connect the MCU through the usb to my lapotp. With the code I'm currently using, the output temperature starts at 2...

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...
