Write JPEG data from ov5640 to SD-Card

HiI am doing a project using STM32L496G-Discovery and ov5640 sensor,what I am triying to do is capture data with a resolution of 320x240 and JPEG format and save it to the sd cardhowever when i open the file created I don't see anything.

I am working with stm32F100 and I want to calculate the time in hours when some GPIO is on

STM32G431KB: I try to make a PWM signal out of my TIM1 channel. I followed this tutorial: https://controllerstech.com/pwm-in-stm32/ My PWM signal goes from 1V to 4.3V and not from 0 to 3.3V. How is this possible?

UART mixed flow control

Hello all,I have a device connected to a stm32l496rg on a custom via uart.At system startup, the remote uart may or may not have hardware flow control enabled, so what I want to do is configure the MCU UART for no hardware flow control and put the RT...

Changing timer frequency by writing the AutoReload Register every 10 microseconds with DMA on a STM32H743

Basically, the frequency change already works. My problem is that the new frequency, which is specified by DMA, only takes effect after the ARR has been reached.I tried to solve the problem by disabling the auto-reload (ARR) preload.unfortunately in ...

STM32L4 STOP2Mode

I'm using STM32L476VG and STM32Cube FW_L4 V1.17.1 version HAL Function.I thought STOP2Mode and RESUME work fine.However, when I took the current consumption waveform, it is the same as STOP1Mode.Why is this happening?void Sleep(void) { MX_UART4...

STM32H723ZG Board losing communication

Hi all,Nucleo-144 Stm32h723zg board while debugging suddenly loses communication and shows target not found, unable to read register values. This does not happen always but during debugging this issue is coming up,any solution or any problem with the...

[Help] Custom Board STM32H7 programming external memory MX25LM51245G via UART

Hello,I am working on a STM32H7 device that needs to be able to program external memory MX25LM51245G using UART instead of STLink. Is there any bootloader available to handle this? Or, what is the best way to tackle this issue? Thanks.

STM32F4 Timer Triggered DMA SPI – automatic NSS > problem - workaround?

STM32F4 Timer Triggered DMA SPI – NSS ProblemI have a STM32F417IG microcontroller an external 16bit-DAC (TI DAC81404) that is supposed to generate a Signal with a sampling rate of 32kHz. The communication via SPI should not involve any CPU resources....
