Dear STM32 team,I am a bit confused about the OCTALSPI device (using it as QuadSPI):Why is it not possible (not supported) to use OCTALSPI also as a regular SPI?Datasheet states that "Single-SPI" is possible - but it means actually: "Single-Lane-SPI"...
This question is about SPI simplex communication.Is there any sample code that realizes SPI simplex communication only by register operations?Also, is there any sample code that uses HAL or LL?I would like to know both cases of sending and receiving....
I have a timer (TIM15) setup in trigger slave mode which uses CH1 for edge detect, and output compare on CH2. I have it working nicely to have the output low during the initial delay until the CNT reaches autoreload ARR. Then the output goes high as ...
Hi!I am somewhat unclear on how to handle variable length transmissions using the STM32F4xx HAL. I have looked at other solutions, and suggestions have been made to use HAL_UARTEx_ReceiveToIdle_DMA() or the ISR equivalent.My situation however, involv...
On STM32F401CCU6I'm trying to reserve these 2sectors for user config in gcc linker script: Sector - Address ini ~ Address end - Size Sector 0 - 0x0800 0000 ~ 0x0800 3FFF - 16 Kbytes Sector 1 - 0x0800 4000 ~ 0x0800 7FFF - 16 Kbytes RESERVE Sector ...
We want to use the STM32U585QII6Q for a new design, and I want to know what I need to do with the dedicated OPAMP VINM pins on this package. We don't want to use the OPAMPs. Do I leave these dedicated pins floating or should I connect them to GND?I c...
Hi.I was in the middle of a debug session in a simple application for the STM32F429I-DISC1 in Keil uVision. I disconnected my board from the computer without ending the debugging session. When I reconnected my board, it wasn't detected anymore and it...
I am trying to configure TIM3 to reset on incoming PWM pulses and call IRQ on overflow, when pulses not coming. The prescaler and ARR are set for 150% of the PWM period. TIM3 in slave reset mode on trigger from CH2 input. MCU is STM32G051F8P.For some...
I used the sample code of "en.stm32cubef4-v1-28-0\STM32Cube_FW_F4_V1.28.0\Projects\STM32F401RE-Nucleo\Examples\UART\UART_Printf"I just printed the "test" in the while(1) loop. but the display of my computer is werid, and I checked the clock and hal l...
Hi all, I am not able to fully understand how the DATA0/DATA1 toggling works when performing multi-packets transmissions. For "multi-packet" transmission I mean that the "num_packets" in USB_OTG_HCTSIZ_PKTCNT register is greater than 1, (i.e. I want ...
