During transmission and reception using STM32U585 LPTIM+SPI+LPDMA, noise to SPI3_SCK causes a fatal bit shift in the bitstream. The condition on the left is normal and the oscilloscope waveform can be received exactly as expected.However, if you intr...
I am trying to implement a USB mass storage using USB3300, STM32H723, and e eMMC. Project Setup:* Clock configUSB_HS ConfigUSB Device configeMMC configIn the code I made these addons in the "usbd_storage_if.c" file:Currently, my custom board is worki...
Hi,I have a PCB with F411 as MCU.MCU VBAT pin is directly connected to battery positive pin.I try to use ADC1 to read the VBAT value. Here is the ADC1 init code: ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER ...
I am using the STM32 Nucleo F411RE, and have 5 GPIO pins set up as inputs, each set to trigger an interrupt on the rising and falling edge, configured to use the internal pull down.However, what I am finding is that causing a level change on one of ...
Dear friends,I am developing a controller using stm32f407vgt6 microcontroller and I'd like to add the capability of firmware upgrade through Ethernet port in my controller.I've read about Ethernet IAP (In-Application Programming) UM1709 but it is no...
Hello, i've been trying to get SPI working in conjunction in DMA.But with "bare metal register implementation" i can't even get the NSS working properly. The Stm32F730 needs to hold NSS/Chip Select high all the time, except for when communicating wit...
I have stm32 board : NUCLEO-L496ZG-Phttps://os.mbed.com/platforms/ST-Nucleo-L496ZG-P/ and would like to make a simple helo word code in C and see out put by SWD debug connector in ITM unit (FIFO), SO i create simple hello word as follow:IDE : stm32c...
I fount this page, ready to gohttps://github.com/cturvey/stm32extldr/tree/main/h7_mt25q128 I do have STM32H743BIT6 and MT25QL128the pins are different, I wonder if it can be opened in something and change pins.
Under what conditions is the U5 website and datasheet claim "16.3 μA/MHz Run mode @ 3.3 V" reached? I do not see anything as low as that in the datasheet and it is far lower than e.g. the U0 claim "Run mode (LDO mode): 52 μA/MHz". Clarification welco...
Hello, I would like to ask you as a beginner in STM32 what product (the best case is the product that is possible to buy with Nucleo kit) I should target to for the application I will describe here:I need to use two ADC channels with 1 MHz each and a...
