I am trying to flash a STM32H735IGK6U using st-flash: st-flash --debug --reset write $(RSLT).bin 0x8000000I get below error here and there, What causes this? If I do st-flash reset and then st-flash erase it works fine again. Programmer/board type: S...
Hello, I would like to configure the DMA option for the SDMMC1 peripheral inside my STM32H747 microcontroller in order to communicate with an external SD in 4 bit wide bus mode using CubeMX, but the configuration setting doesn't appear among the conf...
Hi, I have and STM32F042 and an LCD with an ST7066U from NewHeaven Displays, it is a 3V3 specific version . I am trying to use 4-bit mode to save pins (I have enough pins for this project to use 8-bit but for future projects too it would be better fo...
I need to interface my board using USB type C.I know there's an API for USB type C. Is there a way to download this API, or the SDK that has this API?
Hi,I'm trying to setup this new RAM chips on STM32H735 in OSPI/HyperRAM mode. The HW connection is the same as on ST STM32H735 devkit. I found a driver for similar chip S70KL1281 but there are some differences, e.g. in latencies, but generally S70KL1...
Hello,We have interfaced a NOR flash (S26KL512SDABHN020) with STM32L562 over OctoSPI in Hyperbus mode. The Low level drivers were found from one of the forums of ST community and were ported in our code. We are unable to read/write data at the base a...
Drivinng ann H bridge to generate a sinewave , PWM generated and driving the H bridge .The PWM siganl as followsThe H bridge Connection as shown below.While appling supply the Low side MOSFET Q2 is Heating up Why so ?I added some dead time also nothi...
Hi as i want to use hall sensor interface to my input pwm capture We can see these timers associated with digital hall,Which one i can choose TIM1/8/20 or TIM2/3/4/5 also suggest on 16 bit and 32 bit timer preference. Also can it be preferable to u...
Dear sir/Madam,I have made a custom stm32f303zet6 board for my applications. I started with a basic Led blink program. program is flashing into the MCU but the led blink is not happening. Here i am attaching the schematic for the custom board. Please...
Hey there,I am facing a problem with the clocks on the STM32H755ZI. When I let a timer run at 50 kHz I get only smt. like 49.92 kHz out of it with sigma = 13 Hz. So there is at any frequency a steady offset of -1.2% and a sigma deviation of 0.03%. I ...
