I am confused about which clock(s) drive the timers. In the reference manual is says the APB clock drives the timers but there are 5 APB clocks. Also, in STM32CubeMX there is a "Timer Group Clocks". What clocks drive which timers or is the one dri...
I have questions on the System Memory Boot Mode of the STM32G070CB MCUSetup:Access the System Memory Bootloader Mode every power cycle. Hence, I updated the Option Bytes as below:The MCU contains the Application image only; it does not contain a cust...
I am trying to detect both rising and falling edges on a GPIO input using EXTI.I am using a STM32H755 (144 pin) - SYSCLK is 400MHz, but I am using the CM4 core, so the CPU clock is 200MHz. APB Timer clock is also 200MHz.The signal I am monitoring is ...
How to unbrick a C0 if user firmware reprograms SWD pins as IO? Because by default BOOT0 pin is disabled so there's no way to enter the bootloader unless it's enabled in OPTIONS bytes. I've added a failsafe 2 second delay at bootup before running any...
Whether the two buses can be used at the same time？ Winbond's SDRAM is used to find a high probability of reading and writing errors in SDRAM data。 but there is no problem with using ISSI. If you don't read or write to the external SRAM, it's fine。
I have compared my platforms using PDM microphones related to PDM to PCM and filtering:Platform 1:STM32H747 (Portenta H7), with SW PDM2PCM filter (and optional to add post-processing)Platform 2:STM32U5A5 with ADF filter (in MCU) or external PCMD3180 ...
Hello,I'm planning to use the STM32F413VGT3 in my project. It says it has three CAN buses. Can I use these three lines independently? Some of my research (ChatGPT) indicates that the third CAN line is not a standard CAN bus. I'd appreciate any clarif...
I bought few STM32C071G8U6N from Mouser few month ago.As I know, the SRAM size in spec is 24K, but I will get error message as below when ZI-data over 8KB"Error: L6406E: No space in execution regions with .ANY selector matching xxx.o(.bss)."Program S...
Hello, I have a project to measure the frequency (10Mhz) on an PA5 input and PWM output on PA6, with the counting triggered on PA0 (1PPS), CPU STM32F411, my problem is that the value TIM2 is always wrong, I must have around 10Mhz, I think that the co...
Hello All, @TDK, @STTwo-32, @Peter BENSCH I am using STM32F407G-DISC1 with SN65HVD230 CAN Board Network Transceiver Evaluation Development Module connected to PCAN.Connections are as followsSTM32F EVK pin PD0(CAN1_RX) to Rx of SN65HVD230 STM32F EVK p...
