Hi,I'm trying to set up DMA transfers for I2C sensors on STM32L4R9 MCU.I've followed the documentation and analyzed the HAL implementation, but the DMA channel IRQ handler is never triggered.Here's the specific sequence of steps that I'm performing:F...
Hi ,I am in STM32L071CZ and using window WDG EWI to refresh the WDG counter to avoid RESET.window = 127Counter = 127Prescaler 8Enabling the EWI and reloading the wdg counter in the ISR to avoid the RESET by WWDG.But while writing Flash it seems the W...
Hi,I'm trying to implement Macronix MX25L512 with STM32L476, FATFS and USB MSC.I don't understand why but AutoPolling function timeout.According to the code below, QSPI_Driver_init() is the first function called. QSPI_ResetMemory return QSPI_OK, but ...
We (Steven Burck and Haim Kleinman) have prepared the setups for tomorrows workshops, however, Steven is quarantined till next week and won't be able to make it, and Haim will not arrive to the site until 10AM CET. We have a third engineer who was p...
I read the ref manual several times but it is still unclear to me. I have a problem with a DMA design that is transferring TIM8_CH1 and TIM8_CH3 to memory using DMA_Channel1 and DMA_Channel2. I am getting a transfer error so am looking at what could ...
I am having a but of an issue with setting the registers to portA directly using its address.I am doing this for demonstration/learning purposes. I am using the STM32F401RE board.When I read the datasheet it says that GPIO PORT starts on register ->0...
I want to drive the external sensor to collect images through MCU, and the timing MCU outputs signals in CSI standard format. Which MCU can support this function (MCU acts as a camera)
Hello,As you have requested, I have ordered the board via ST e-store on March 1st. Also, I have got the order confirmation from ST.Further, when can I expect to receive the news of the seat reservation from ST ?Thank you and with my kind regards,Sue
Hi to all the community.I have to save in non volatile memory some small amount of data,say 200 bytes.STM32F446 has different sector sizes,sectors 0,1,2,3 size= 16KBsectors 4 size= 64KBsectors 5,6,7 size=128KBIn other microcontrollers ...
I am using STM32H745ZI for a personal project. Page 60 of the attached datasheet from ST says there are I/Os that are floating unless otherwise specified. I want to use an I/O that I can guarantee will be in either low or high state on a reset or if ...
