hi guys, i work on STM32 L4R5ZI without HAL functions.I use DMA for LPUART(for HMI) and SPI (for component) and I want synchronize these communication with DMAMUX. I see in the reference manual, some synchronization signals (EXTI, dmamux_evt,…), I wo...
Anyone know of any alternative hardware solution(s) from other manufacturers that is equivalent or providing similar protection features as the STSAFA100DFSPL02? Namely STSAFE.Thanks.Ref to STSAFA100DFSPL02: https://estore.st.com/en/stsafa100dfspl02-...
Hello Dear Engineers and Developers,This one is an advance question for me, perhaps as easy as ABC for you.I want to put image data on the external ram. Either of Keil or Stm32cubeIDE compilers are acceptable. I know that I should change the linker s...
I'm using smaller MCUs (L4, F3, ...), but I'd like to learn running the code from external memory.Use case: not change the MCU to the bigger one, but add external memory e.g. via QSPI.I thought this workshop is good starting point.
For IEC60335-1 class B compliance, CPU registers should function well(Should not be stuck at faults). To test those faults we need to send/store some instructions to those registers. What if those registers are stuck at fault? I mean If it is stuck a...
Hello. I have a circuit containing notably: (i) MCU pin PA2 connected to both a ULN2003 transistor-array input and a 10k pulldown resistor and (ii) the corresponding output of the ULN2003 is connected to a small beeper GND. In theory, this circuit is...
Hello,I have the RTC set for a 1 Hz interrupt. I have buttons, that when pressed, trigger a rising edge interrupt. The interrupts work fine except that when I call my button handling routine the RTC interrupts are blocked. They remain block until the...
Hi,I am having some trouble with the CAN peripheral on the STM32F103C8Tx. I am using the HAL API's (via STM32CubeMX) to configure the device. I am using the device in loopback mode to test.Up to now, I can successfully get the CAN peripheral to work ...
hi community,I am currently using the STM32H743ZI board,in the reference manual it is written like this"The clock provided to the MCOs outputs must not exceed the maximum pin speed (refer to the product datasheet for information on the supported pin ...
I have been told i need to sync 2 STM32 MCU's together (on the same PCB) to stop an intermittent I2C bus failure between them. At the moment they are operating on separate 8Mhz crystals. I have used the following command to configure and output the 8...
