Posted on February 20, 2017 at 12:37Hello,can the information be made available how the on-chip USB bootloader generates the serial number?This would be helpfull when an application provides a DFU endpoint to jump to the built-in USB bootloader. As...
Posted on March 16, 2017 at 05:07I have my jump function that successfully jumps to the bootloader memory from the running code.Now the processor is supposed to (according to AN3155 - USART protocol used in the STM32 bootloader):Once the system memo...
Posted on March 13, 2017 at 18:05Hi all,I am new to the STM32 and I am struggling with determining whether or not I can get PWM and Encoder input working on the same timer.I have a Nucleo-F103 board and using CubeMX, I have set up my board to use Ti...
Posted on March 15, 2017 at 17:38Is there a function or macro for determining the frequency of APB1PeriphClock and APB2PeriphClock?Thanks,jh#apb1periphclock
Posted on March 15, 2017 at 09:58Hello,I have programmed my board (STM32L475) with the example '...STMM32Cube_FW_L4_V1.7.0\Projects\STM32L476RG-Nucleo\Examples\PWR\PWR_STOP1_RTC\MDK-ARM'. I measure current consumption and it is higher than the expec...
Posted on March 12, 2017 at 16:56I'm sorry in advance for such a stupid question, yet i can't find my error.I have some chinese nameless 'stm32f103c8t6 system board' with F103C8T6 on board. I also use Coocoox IDE and ST-Link v2 programmer. The follo...
Posted on March 14, 2017 at 03:29I have STM32L432 Nucleo board. Using CubeMX I have configured the ADC1 IN17 to temperature sensor channel.How do you read this register using the HAL layer?I can already poll adc1 IN5 to read an external temperature ...
Posted on March 10, 2017 at 14:27Hello everyone,I am working on a project with a STM32L151 microcontroller.I want to be able to upgrade its firmware via DFU mode.The DFU driver is well installed, the device goes well in DFU mode when needed, I can w...
Posted on March 14, 2017 at 07:19MCU: STM32L443VCT-I am calling 'HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI);' from the main application of my code but it seems that the function returns immediately (MCU not entering STOP2 mode). What I might be doi...
Posted on March 11, 2017 at 16:25Hello!Is the whole STM32F7 family pin and firmware compatible (besides missing peripherals?).I know that 7x3 and 7x2 aren't compatible with the rest due to inclusion of HS USB PHY, but what about the others?If a desi...
