The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi,I need to generate a special waveform via DAC on a STM32F446. DAC samples must be generated at about 240kHz but with minimal jitter. A DMA channel with timer trigger will provide the data from internal RAM or flash. What best case - minimal - jit...
Hello everyone.I'd like to ask about the possibility of purchasing pre-programmed STM32 parts with our application.For now, we expect a low volume production in the mid term, but it is expected to grow around 1 year after product launch.Is it possibl...
Hello, my work mate made a design where we have to measure a low voltage in a smaller range (0-.120mV) on an Input.His assumption and hardware realization to meet the requirements based on datasheet DS10690 Rev 6. Here on page 63 you can find the ta...
I am encountering with a following problem in MCU STM32L432B.1. When the MCU enter to low-power mode (Stop 2) ones does not wake up while VDD is low than 2.1V, instead of it turns to mode with power consumption more 10ma. 2.When operation of the MCU...
STM32F446 RTCI seem to have a problem with this part of the MCU.I am using the HAL to retrieve date and time.Yesterday evening I set the time (about 22h something).Time was displayed correctly.Today in the morning I have a time of 33h27 retreived by ...
Hello, guys!I have problem saving data in STM32L0's flash memory.If I save the data twice in the same location it works fine.If I save the data once CRC check fails - data writing goes wrong?!I have attached my code.Sorry for the "magic" numbers in t...
Hi Everybody,I have a difficult problem. I use STM32F469I-Disco to porting new LCD on it.My LCD driver IC are ILI9806E and ST7701s. they are having the same problem.they can be lighted on, but image is not the same as my setting.Example: I use BSP_LC...
I have a nucleo F746 board powered from CN1 (USB from the ST-LINK side) and I am interested to use the other USB port (CN13) configured as Virtual Serial Port (VSP) and start debugging with the printf () and log on a PC (the STM32 does not yet have ...
I have inherited a PCBA that needs to generate a fixed number of PWM pulses on TIM2 CH4.I have successfully setup TIM1 as the Master (with repetition count = 0) and TIM4 as a Gated Slave.TIM1 CH1 is generating 2kHz PWM indefinitely.TIM2 CH4 is genera...
