Resolved! Writing BMp file to SD Card
Hello, I am trying to write a camera image to an SD card.I am able to write and read bmp file from PC for 160x120 sized image. However I can not read bmp file from PC for 320x240 sized image. I used below file header format. Every thing is the same e...
STM32H747 LDO power config
I'm trying to configure my custom board to only use the internal LDO, bypassing the need for the SMPS. In fact, my board doesn't even have the SMPS components. Is this allowed? The user manual seems to suggests that we can exclude the SMPS circuit ho...
Hello! I am working on a project using the STM32H747 dualcore. The M4 core is responsible among other tasks for sampling a fairly quick digital signal (5-10 Mhz). I am looking for a hardware interface on the H7 that will allow me to sample this signal.
the sampling logic and countig is not very standard:1) If A = rising edge and B = 0, counter++2) If A = falling edge and B = 1, counter++3) If B = rising edge and A = 1, counter++4) If B = falling edge and A = 0, counter++5) If A ...
RXNE Flag of STM32F302R8 is never SET
Hi, I have a problem where my SPI SR RXNE in STM32F302R8 is never SET, causing my program always halt in while loop, waiting the RXNE status to become SET, when receive data.how I set the RXNE flag is below:#define SPI_SR_RXNE 0#define SPI_RXNE_FLAG...

Can't start first code with NUCLEO-H755ZI-Q
I bought a new NUCLEO-H755ZI-Q board. It's my first STM32. I use MXCube to create a new project for MDK-ARM. I tried both STM32H755ZI and Nucleo-H755ZU-Q. And I enter my code in Application/User/CM7/Core/main.c . Between line 163 "/* USER CODE BEGIN ...
Resolved! In input capture function , i am trying to interface HC-sr04 Ultrasonic sensor to STM32F401. I am giving input to TRIG pin with 10 micro seconds ON and Need to Measure Pulse from ECHO pin of the Sensor and not getting Exact Width.

Resolved! How to enable Capture/Compare 1 output Polarity(11: noninverted/both edges) in TIMx_CCER Register(STM32F401RE) but only 1 Bit is allocated for CC1P?
In detail glance on RM0368 Reference manual. I am getting confused while enablingCC1P -Capture/Compare 1 output Polarity(11: noninverted/both edges) in TIMx_CCER Register(STM32F401RE) .Whether it is possible to change Output Polarity into both Risi...
