Title and content edited: modified MPU by MCU. There is a big differenece between MPU and MCU products Hi, we are currently selecting an STM32 MCU. We need a dual core M7+M4 and so we've spotted STM32H757, so far so good. Unfortunately we (lately...
Hi all,I want to use the EMMC as USB storage space.After connecting to the computer and successfully formatting, I found that the file transfer speed is very slow (write speed is 1-2 Mb/s, read speed is 2-6 Mb/s).After enabling DMA, the speed still h...
Hi,I’m trying to confirm the supported year range for the built-in hardware calendar in the STM32L452RE.Since the RTC year register is two digits (00–99), does this mean the calendar supports dates from the year 2000 to 2099?I’d appreciate it if anyo...
Hi everybody,I used a STM32F446 to communicate on NMEA2000 (CAN bus).The two pins (RX/TX) of my µc are connected to an isolator SI8621 (https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/data-sheets/si861x-2x-datasheet.pdf) and then, a ...
Hello, I have two channels on ADC1 and I want to trigger a s ample separately, every two seconds from first channel and every 10th second from second channel. I am using interrupts so after the adc trigger I get an interrupt when conversion is done....
With a stm32c0116-dk, I am attempting to read vrefint, and calculate vref+. From my understanding of the data sheet, and schematic. VDDA is tied to VREF+ . On the development kit, these voltages are 3.3V.VREF+ = ((VREF _Charac+) * (VREFINT_CAL)) / VR...
Hello Team,We are planning to use STM32H7S7L8H6 in our design. With this part we want to integrate quad SPI Flash memory (Part Number : W25Q128JVPIM with 3.3V Vcc).So, in STM32H7S7L8H6 VDDXSPI supply voltage 3.3V is ok, right? Thanks & Regards,Jigne...
Hello, do you know if we can transmit data formats of 32 bits via SPI in NUCLEO-L552ZE-Q. and if yes, how?
Hello all,I am on the STM23 H750 discovery dev. kit working either in Keil or CubeZone IDE-just started, anyway, so far so good, and according to the logic analyser the LIN works, at least the checksum is right :) So far I am sending the frame once t...
Hello,I have an issue and until now didn't find the solution :Using ADC2, one channel IN12, triggered by timer every 100µs, using circular DMA sized of 16 half-words, the array [0] value is always 0, the array's index used by DMA is from 1 to 16, not...
