Posted on February 22, 2018 at 15:24Hello,Have a STM32L432 Nucleo 32 board. I am using the CubeMX to initialise some code and I see in Workbech that within drivers/CMSIS there are much more files that others STM32 projects.The point is that there t...
Posted on February 28, 2018 at 11:35 Hi, I am using STM32F446RETxNucleo board formy application. It was working fine till I added a new operations including asynchronous data exchange on UART5. Now, sometimes during data exchange on the seri...
Posted on January 18, 2018 at 17:49Hi everyone! I'm using an L071CBTx and I'm trying to figure out how to change the ADCs clock source using CubeMX. According to the reference manual, 'the ADC can be derived either from the APB clock or the HSI16 ...
Posted on February 28, 2018 at 16:24The stm32l432 lacks the PORRSTF flag that other stm32 processors have, so I don't see a way to reliably detect a power-off/on event. I tried parking a bit in the backup registers, but it doesn't appear that this ...
Posted on February 28, 2018 at 09:08Hi, I'm designing a low power application using a L452RE. In order to keep the power consumption to the minimum I turn ON and OFF the peripheral clocks only when I need to use the peripheral. My question is what h...
Posted on September 21, 2017 at 14:36Hi all!We encountered a problem while we wants to program our Display Controller Unit. In our previous prototype we used a QSPI Nor-Flash MT25QL256ABA8ESF-0SITWe could use the available bootloaders found in ST-LI...
Posted on February 28, 2018 at 06:27Hi, I'm new to Stm32 but I've used alot Arduino. I have the Stm32L4 on a custom board and first I would like to control a brushed dc motor, I have a pololu motor driver with In1,In2,Pwm etc.Is there anywhere to ge...
Posted on February 27, 2018 at 12:25Hello!Our customer has a problem:'We tried to connect m66-ds modem to STM32F207VE, scheme in attachments. I2S initalization code is generated in CubeMX. We tried to work with I2S interface using interrupts, it wor...
Posted on December 18, 2017 at 16:54Hi!The LL library causes a compiler warning (dereferencing type-punned pointer; see below).Can I ignore this warning?-Thomas/STM32Cube_FW_F3_V1.9.0/Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_ll_crc.h:355:3: warnin...
Posted on February 28, 2018 at 06:10Maybe I ask a simple question about what the meaning of stm32's model namelike 'stm32f407vgt6', what's the 'v', 'g', 't', '6' mean? or f407 I know '4' is about cortex-m4, but 07 means something special?Thanks a lo...
