Hi all, im using Cube IDE STM32H743ZI2 Evaluation boardim curently sampling ADC2 and storing the output at an internal array using DMAthe array size is uint16_t[100,000]my requirements as to store much more data which means i have to use a diffrent m...
Hello,I recently upgraded to CubeIde 1.6.0 but I am having many new problems when programming STM32h/43: the configurations generation is much slower and it often stops updating all needed files, which forces me to reboot (I could not find a better w...
I need USB interface STM32F373 for circuit.
Three states on a single GPIO pin with two LEDs is possible.For users who want to drive 2 LEDs with three states with one signal GPIO - please, see the details below.But I want to ask one question:On a STM32U5A5 - how does the PC13 behave? - I see "F...
Hi everyone,I have a STM32H573I-DK and try to port FreeRTOS without TrustZone to this board by CubeMX but suffered from a problem.I installed the X-CUBE-FREERTOS, set TIM17 for HAL Tick and SysTick for FreeRTOS.It will block (or crash?) in vStartFirs...
Hello,I have some questions regarding Ethernet frame transmission.1) When is the value of the "ETH_MMCTGFCR" register increased?After calling the "HAL_ETH_TransmitFrame()" function, I noticed that the value of the "ETH_MMCTGFCR" register increased in...
Hi,I am Using an stm32f205 on our board. All the Uarts works fine at room temperature. But when the temp increases above 58 degress, messages started get missed in the uarts or sometimes it completely stops sending messages.I am running the board at ...
In STM32L432KC(arm cortex-m4+FPU) there are two ram memory blocks. Following is a snippet from the linker script I use._e_ram2_stack = ORIGIN(RAM2) + LENGTH(RAM2); _e_ram_stack = ORIGIN(RAM ) + LENGTH(RAM ); ... RAM (xrw) : ORIGIN = 0x20000000, LENG...
I have successfully configured USB On-The-Go (OTG) on an STM32 microcontroller to support both Abstract Control Model (ACM) and Human Interface Device (HID) protocols. I utilized the stm32_usbotg_eth_config.sh script as a reference, and the setup is...
I need to measure the time it takes for a component to reach a certain voltage, read out with the ADC. So far I have been measuring in microseconds but it turned out that that is not precise enough.I found the following code to measure time on Stacko...
