I have a project in which I try to sync my assembly code on a signal on a GPIO, using WFE for minimum latency and jitter.I use a Rust HAL ony for initialisation of the clock and to put some GPIOs into input mode, and one in output mode that I use to ...
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: Cor...
Hello, we intend to implement a time-dependent channel change via the operational amplifier in voltage follower mode, as described in AN5306 - Rev 1 Page 31, 5.1. However, when checking the output, there is an unwanted gain (x2) on channel 2. Any ide...
hii am using stm32u585 controller for my project . here i enabled the internal tamper detection using the below code /* USER CODE BEGIN TAMP_Init 2 */ sAllTamper_inter.IntTamper = RTC_INT_TAMPER_1|RTC_INT_TAMPER_2|RTC_INT_TAMPER_3|RTC_INT_TAMPER_9;...
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 ...
