I am trying to control 8 independent pulse channels using 8 independent pins of the STM32F407. Each pin will supply the pulse pin to a different motor, so I will be controlling 8 independent motors with the microcontroller. For each pin I am assignin...
HiI am designing PCB with the MCU above. I do not have any devboard for now with G0 to check what I need.I want to utilyze the REFIN function of the RTC. I also need to check presence of this signal (if there is no 50Hz signal for some time [few 100'...
i just received my brand new stm32h747 discovery board, on power-up it does nothing just two LEDs light up, according to the user manual it should be preloaded with a demo.I checked in cube prog and it reports as blank.Is it possible that my device g...
Hi, I have an application code(Call it as Code-1). I able to dump it into my custom STM32H735 board through ST-LINK V3 MINIE. But when i try to dump same code for second time, it showing below error," Target no device found"Error in Initializing...
There is glitch when accessing timer registers using DMA- Halfword memory to halfword peripheral DMA transfer- DMA target is TIM15->DMAR, configured to write ARR register.- TIM15 dithering enabledUnder these conditions, bits from ARR[3:0] will end up...
Hello, got Nucleo F439 kit, amazed to see no cables in it.Wanted to check if the cable "USB Micro-B connector (CN1)" is same for "USB Micro-AB connector (CN13)" connected in reverse?Cause Im not able to identify cable "USB Micro-AB" to buy.
Hello,I have waisted 2 days already on trying to figure out why interrupt is not being triggered when using CAN RX.I started new fresh project just to test the CAN and debug it so there is not much initialized here.So sending data via CAN works for m...
Hi. I'm using Keil5.ADC encountered an error in my program(from function HAL_ADC_PollForConversion), so I tried debugging and found the following problems. As shown above, the register value in CFGR1 returns the address.In a typical program(Operating...
Hi amazing community. I am developing a custom bootloader for stm32f429 .I have touched the linker file that i show here ****************************************************************************** ** ** @file : LinkerScript.ld ** ** @a...
I need to generate a checksum of data from X address(FLASH) to Y address (FLASH). and write at last 4 bytes of FLASH memory in "xyz" section. When I say calculate checksum, I mean addition of all given data bytes from X address(FLASH) to Y address (F...
