In the STM32F446xC/E datasheet, DocID027107 Rev 6, footnote under Table 11. Alternate function says:1. The DCMI_VSYNC alternate function on PG9 is only available on silicon revision 3.However, neither DBGMCU_IDCODE description in RM0390 Rev 4, nor ST...
When i m using circular ADC1 DMA and writting data on sd-card,mostly data lost, why?
I have the system clock set as 120Mhz. I used the HAL driver code, HAL_PWR_EnterSLEEPMode, to enter Low power sleep mode. However, when it checks if it's in run mode, it doesn't recognise its actually in run mode. /* If in run mode, first move to...
Hi,Can anyone recommend the best way to generate microseconds delay??and how to generate it??
Hello everyone,We're working in a design with the STM32L151ZE and a power supply of 3V. We're trying to design a connector able to detect when specific resistances are present.I've seen that there are some inputs of the chip that are 5V tolerant, whe...
I wish to use my STM32F429 as a top-notch audio player, driving a good I2S DAC. 192KHx, 24bit, stereo. First of all, can I bypass the internal clock scheme by sending a high quality clock to PC9 (I2S_CKIN) ? From my calculation, I'd need a 49.152Mhz ...
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...
