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 ...
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...
There are two situations where I'm unclear on how CAN filters would behave. 1. Direct ConflictOne filter says reject 0x0 to 0x123One filter says send 0x0 to 0x123 to FIFO0 2. Different behaviour for a subset of messagesOne filter says send 0x0 to 0x1...
Hi everyone,I'm using the NUCLEO-H755ZI-Q board and I’m a bit confused about its Ethernet support.The user manual (MB1363 Rev C) shows that both H745ZI-Q and H755ZI-Q support Ethernet using the LAN8742A PHY. It also lists jumpers and solder bridge se...
