Background:I am capturing an image on OV5640 Camera module. My camera is connected with STM32L4R9I over DCMI protocol. I am further using DMA1 to take image data and store it in PSRAM (with the help of FMC). From PSRAM, image data is being written on...
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...
