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...
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 ...
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...
I was doing reset through SPI command and expected results are not happening. this is the line i was expecting to reset the MCUSCB->AIRCR = (NVIC_AIRCR_VECTKEY | (SCB->AIRCR & (0x700)) | (1 << NVIC_SYSRESETREQ));where#define NVIC_AIRCR_VECTKEY (0x05F...
Since the description of the FDCAN controller in the reference manual ofthe STM32G474 was not detailed enough, I looked around for more Informationand found the Application Note AN5348 ("FDCAN peripheral on STM32 devices ").But that didn't make me fe...
Hi all,I've been working through this tutorial: How-To-Create to bring up LWIP + FreeRTOS on the STM32H735IGK development kit. I'm using STM32CubeIDE 1.18.0, FreeRTOS with CMSIS-v1, and STM32Cube FW_H7 version 1.12.1I noticed that pinging is very sp...
