We wanted to use the uart2 serial port of STM32F072CBT6. We used the STM32CUBE tool to generate the code, but the debugging found that we could not enter the interrupt of uart2.We had no problem setting uart1 and uart3 to use before.The initializati...
I have an app that uses SPI5 on an F7 chip with no problems, but it no longer works when I upgraded to the H7 chip (at the same time I changed to using SPI2).I am no longer getting the serial clock signal (SPI_SCK) on SPI2 on the H7 chip.I defined SP...
With the data cache enabled is the backup ram cached such that an Invalidate Cache instruction is required to write the data through?
This is a minor thing, but.... STM32L433xx/STM32L443xx Errata sheet, ES0318, revision 4, section 2.1.2 on VDIV/VSQRT says there are two work possible arounds, but then lists the same work around 2 times (disable lazy FPU context save). What is the ...
I'm using a Nucleo-H743ZI and have configured ADC3 to trigger off of TIM3. It is scanning 4 channels every 10 us. I also have BDMA configured for the ADC. The ADC end-of-scan interrupt is occurring every 10 us, but the DMA interrupt is only occurr...
I just received version 2 of a board I designed. It has two STM32F427 on it. One a 144 pin used for main processing and the second a 100 pin used to control IO.The 100 pin MCU uses Ports B, D, E (all as outputs) to control outputs.Version 2 of the ...
Hi Guys,I working on a project that require measure time difference between 2 PWM (Refer the picture below) . I was able to measure the PWM frequency using input capture method but not able to measure the time difference, Td between 2 PWM. Kindly nee...
So why this issue in the STM32L1 discovery board.I also uploaded images regarding the problem in the board.
I see that some libraries from the SDK (Like the PLL State Observer) are delivered as precompiled objects for each of the supported IDE's. Is it possible to obtain the source code of these libraries in order to use them in our project's IDE? (Since w...
Hi, I am learning how to use Uart and created a simple example project where I sent 'hello world'. i then use RealTerm to view this message. i have generated this project using CubeMX and it works however i flashed the board once and after that i can...
