Resolved! STM32U5A5: PC13 with two LEDs - FOUR states (instead of three)?
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...
Resolved! Problem of porting FreeRTOS to STM32H573I-DK by CubeMX
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...
STM32F439 Ethernet Frame Transmit Jitter
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...
STM32 UART stops At High Temperature
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 ...
Resolved! Using end of memory address as process stack pointer value causing INVPC hard fault.
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...
USB gadget
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...
Resolved! Measuring elapsed time in nanoseconds
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...
