Can the L4R5 OCTOSPI interface be configured as a slave
Hi,Can the L4R5 OCTOSPI interface be configured as an SPI or Hyperbus slave so that it's flash memory can be accessed and addressed via SPI from a master device?Is it possible to configure the L4R5 OCTOSPI so that the device appears as an external fl...
STM32H7 datasheet SPI characteritics are not clear
Hello,The SPI characteristics in the STM32H753 datasheet are not clear (for me at least):What does "slave receiver mode" means ? Is it half-duplex or simplex communication ?Right now I'm able to communicate between two STM32H7 Nucleo boards connected...
Resolved! Force DMA stop for Burst mode on stm32f7xxx
Hi,I am working on eval stm32f769. I have used DMA burst mode in circular.I want to forcefully abort DMA stream and DMA, so that on I can restart DMA burst with different sequence.I have used HAL_TIM_DMABurst_WriteStart() API for starting burst mode ...
DMA burst sequence does not gets started immediately
Hi All,I am using STM32F779I- eval kit.I am using DMA Burst mode. I have created two buffers(buffer1 and buffer2) with different sequence.Lets say Buffer1 with sequence 1 is running using HAL_TIM_DMABurst_WriteStart () HAL API. In between of sequence...
[STM32L431] VREF unstable when using STOP mode and toggling on/off DAC
Hello,I'm observing a stability issue on the internal voltage reference while using STOP mode.I'm using STM32L431, with : - VCC=1.9V - VCC_AN=2.8V - internal reference set at 2.5V with output buffer enabled in low impedance mode, decoupled with 100nF...
STM32H747 ADC resistance R_ADC missing from datasheet
Hi,I'm working on a project where I need ADC readouts with very little jitter and therefor use synchronous mode. As I have several side conditions on the clock domains, I can't choose the ADC clock freely. Hence, I'm trying to evaluate if for a given...
Resolved! STM32G0 input structure and clamping diodes - especially in analog mode
Hi,published io port structure in STM32G0 reference manual does not show input clamping diodes.So: Need to provide them externally ?Or: Bug in io port sketch ?Best regardsJuergen
Resolved! input capture problem in coding
Hi friends, i am capturing frequency using timer pins(Input capture mode).MCU = stm32f103c8t6Software = Keil uvision 5Debugger = st-link v2I capture frq using timer 1 ( TIM1_CC_IRQn ) channel 1 which is A8, which works awesome.I tried s...
