I've spent some time recently trying to prototype a small project based on the STM32H503 which would need to have the ADC and DAC running simultaneously with multiple channels of analog I/O via DMA. I was able to get this all coded up but discovered ...
Hi,I'm using an STM32H7 microcontroller and need to get the RTC working.I set RTC_OUT to 1Hz and set the LSE to a 32.768Hz crystal, and inserted the CR2032 battery.When the microcontroller is powered (VDD 3V3), I see the waveform oscillating at a fre...
Hello everybody,I'm trying to get from a pulled up state / driven up state to a tristate pin without losing the charge that is on that pin.It seems to me, that whenever a pullup is deactivated (PUPDR), that STM32 will first discharge the pin and then...
Hello Team,We are Looking to select MCU Which has High Speed SPI and QSPI in a Single Device ,High Speed SPI - 50 Mbps to 90 Mbps ( One channel ) to interface External Ethernet Controller QSPI - ( One channel ) - to interface with External Motion U...
I designed simple board around STM32C011J6 MCU (SO8 package). I'm using fresh-from-packaging parts, ordered from Element14 (Farnell). When I try to connect to MCU (via SWD, using ST-LINK/V2 ISOL), I get "Can not read memory! Disable Read Out Protecti...
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....
