The errata sheet of these MCUs says:2.16.2 Wrong data may be read from Message RAM by the CPU when using two FDCANsDescriptionWhen using two FDCAN controllers, and the CPU and FDCANs simultaneously request read accesses from Message RAM, the CPU read...
Hi, I always appreciate all members here for helping beginners like me :)I am currently working on a project using Timer and ADC+SPI with DMA.The main timer loop is running at 40kHz, and this frequency should be strictly guaranteed.Two DMA process...
I'm checking the ADC operation with STM32H7B3I-DK board.To set adc clock frequency up to 50MHz, i tried to change BOOST bits of ADC_CR register.However, unlike the rm0455 document that states that bits 8 and 9 (BOOST bits region) can be set, when ...
HelloI am trying to delay a 1Hz digital signal.I would like to generate a delay varying from a few microseconds to 10 ms.I tried to use ETR, TI1_ED and PWM input but I didn't manage to found out how to do.Does anyone has an idea on how to proceed?Bes...
Error :Messages for model XXXX：Vmeas_(rising/falling) is set,It is necessary for delay neasurements. satisfy Vinh >= Vinl.
I am exploring the memory space of my STM32F051 using a very simple hex monitor that communicates through a serial port. I can (attempt to) read/write a byte at any arbitrary address in the 32-bit address space. Within the SRAM area (starting at 0x20...
How to set up white noise in stm32g431kb DAC?DAC works, I can produce sine wave but cant generate white noise.I set DAC->CR WAVE1 to 01 (noise), DAC->CR TEN1 to 1 (trigger enable) and DAC->CR EN to 1 (enable). Tried to set also DAC->CR MAMP1 from...
I am using receive DMA to mange reception of data on UART4 and UART5.The setting of both UARTs is identical. UAERT4_RX is using DMA1 Stream 2UAERT5_RX is using DMA1 Stream 0I’m using halt transmit, transmit completed callbacks and idle interrupt to m...
Hello dear experts,Reading the ST literature abour QuadSpi, I noticed that they only mention the flash as available peripheral chips on the QuadSPI Ibus. i would like to increase the amount of RAM on the stm32F446RE to create a buffer when writing to...
