STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi - I have a new board with very minimal parts other than a STM32L451VET6 micro and a SPI LCD.I have implemented SPI and the micro is sending data when I single step the program. When I just let it run it Sends exactly three and one half bytes... ev...
Hi,we have an image, install on few SD cards. Most of them boots just fine, but few of them get stuck at "Saving Environment to MMC...".I tried to reduce the SD clock to 25, 12.5MHz but it doesn't help. Does anyone know where the point to investigat...
Hi,I have background knowledge of programming and MCUs but I am fairly new to the STM32 ecosystem. I am trying to measure the RPM of a motor using an optical encoder that gives pulses on the output. I have done this on Arduino using the interrupts an...
Hello,I would like to design a microphone array with up to 16 microphones. I want to use the stm32h7a3zi board which has a lot of peripherals.I was looking at the DFSDM interface, but with only 8 channels / 8 filters up to 8 pdm microphones can be ha...
HiSTM32 mcu finder for iPhone is fine.But, STM32 mcu finder for iPad is stuck with a component database dated Jul 14, 2021 20h18.It's a way to have an updated database ?Thanks in advance
Lets say i call HAL_SPI_TransmitReceive_DMA() and then I get an error or I decide to timeout while waiting for SPI data. What is the correct way to recover from an SPI error or a timeout?I use this code and it seems to work: // De-init SPI2 ...
Here, i am working on STM32F401 controller, where i am using PLL with HSI working at 72MHz freq. The timer is generating a PWM output but instead of generating 24 pulses as per my requirement it is only generating 6 pulses. Hence 2 pulses for every 8...
I have an array of times, currently TIM3 and TIM4 on a STM32F373. I may want to add more timers in the future, so I enable them in a loop. Is there a way to ensure they all start at the exact same time or will the loop iteration be so fast that the...
I want to read voltage of an analog waveform of 1khz after 50us of every rising edge and skip other reading of every cycle how to configure adc in stm32 if anyone have code for this please help..
