Hey guys,I'm trying to understand STM32F334 high resolution timer (HRTIM) in some details.It says the timer has 217 ps resolution. But how can I achieve that in practice? Let's say I generate PWM signal with 1MHz frequency and 500.00ns pulse width. (...
I have a strange behaviour on a new project with a STM32H743 processor and I am currently stuck.After a successful (HAL returns HAL_OK) erase operation of a flash sector (e.g Sector 4) the blankcheck routine - which worked on all of my other H743 pro...
Hi, using STM32G071 Nucleo Board.Set Vref to internal 2.500 Volt.Set jumpers accordingly (SB28 ope´n, SB21 close) and measure 2.5001 at pin AVDD (CN5.8) on Nucleo Board. So far, so good.Now try to determine AdcVref in software by reading ADC_CH_VREF ...
Hi everybody,I'm using an STM32F469BI and I'm trying to receive on both Can1 and Can2, and handle messages on both FIFOs. For example, my board can be commanded to wait for messages on CAN1 FIFO0 and CAN2 FIFO0 or CAN1 FIFO0 and CAN2 FIFO1,..So i'm a...
Hello,I have to do flash via dual boot option on a STM32L476RG board using an external board NUCLEO- L476. when I am trying to change the option bit via program in which i am using HAL_FLASHEx_OBGetConfig and HAL_FLASHEx_OBProgram in our main program...
Hello everybody!This is my first post. I hope that i am on the right corner of this Q&A section.For an application i need a MCU that is capable to run the SPI with a clock-frequency of at least 80MHz (Master transmit) and at least 50MHz (Master recei...
I have an stm32h745zit6 on my own board, where I can write correctly to the CM7 section (0x0800 0000 to 0x080F FFFF range) but not to the CM4 section (0x0810 0000 to 0x081E FFFF range), I also can't do a full erase of the chip, and it will give me an...
Hi All,My STM32F0 happily makes multiple channel ADC conversions and transfers them using DMA. However, when I flick the I2C into Fast Mode Plus mode (1Mb/s), there's no ADC conversions or transfers. It actually generates a DMA overrun, but there a...
ADC_CommonInstructure.ADC_Mode = DC_DualMode_RegSimult-----what #iclude should point to?
I want to used NAND Flash with QSPI interface in STM32L475VGT6. Its not clear in the datasheet if NAND can be used on one page NAND driver shows up on block diagram and another one under the revisions of the part it says NAND has been removed.Can you...
