I am working on the NUCLEO-H755ZI-Q, which contains a dual-core STM32H755 (Cortex-M7 + Cortex-M4).I configure the system clocks in CubeMX as follows:SPI1/2/3 Clock MUX: 400 MHzSystem Clock: Configured for high-speed operationCM7 core frequency: Corre...
Hello,i have a STM32F114 (Black Pill V3.0) and a strange timer problem. We all know that when setting the APB1 clock divisior is > 1, the APB1 timers gets twice as fast (2x, TIMPRE bit is not set). However, my timers are 4x when the divisor is > 2 (R...
Hi all,I'm currently designing a board that requires using an stm32h723 with USB HS (I need more bandwidth than FS allows). The stm32h723 I'm using doesn't expose pc2 or pc3, which are needed for ULPI DIR and NXT respectively. Instead, pc2_c and pc3_...
We are using STM32U5G9's I2C with a diff-I2C to single ended I2C converter IC PCA9616. PCA9616 is used to program the STM32 MCU over I2C1 by converting diff-I2C to single ended I2C.However, while probing the I2C1 of the STM32U5G9, we are seeing negat...
Hello,We are currently using the STM32G070CBT6 microcontroller in one of our data logger devices, which operates on a three-phase power supply and is used in a transformer application. In our design, the microcontroller triggers a relay, and the rela...
I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
In rm0316 rev 10 for the stm32F303x, the documentation for the ABRQ bits in the CAN_TSR transmit status register states: Setting this bit has no effect when the mailbox is not pending for transmission. I am finding on my STM32F303 that setting ABRQx ...
New question = New thread. Split from this post. Hi mƎALLEm, Thanks for the support, I was able to successfully perform UART-based flashing. For the actual use case, I need to flash the STM32F767ZI Nucleo using the CAN interface. I have a PEAK USB-to...
Hi Sir,Does any STM32 MCU support two independent USB 2.0 High-Speed (480 Mbps) interfaces simultaneously? I have observed that current H7 parts limit the second core to Full-Speed only. Do any newer series support true dual-HS operation?Thank you.
Hello everyone,I am migrating a design from STM32F446 (UFBGA-144) to STM32H533 (UFBGA-144) and noticed that FMC-SDRAM is no longer supported on the STM32H533.On the STM32F446, the FMC supports SDRAM and provides signals such as SDCLK, SDCKE, and SDNE...
