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...
Hello Team,With RDP set to Zero Level , Firmware upload succesfully using CubeProgrammer GUI ( USB DFU mode ).But If I set RDP LeveL 1 , Device not able to detect on PC device manager and not able to connect with STM32 using CubeProgrammer USB interf...
TL;DR: Two-node bus: STM32 (FDCAN1) ↔ CANable (SocketCAN) at 500 kbit/s candump can0 shows frames from STM32, but STM32 keeps flagging ACK error and increments TxErrorCnt. Scope on CANH/CANL (diff trace CH1–CH2) shows a dominant ACK bit in the ACK...
Hi,I'm interfacing external ADC - 16 bit, 10MSPS (AD7626) with this microcontroller. STM32 SPI will work in slave mode, ADC will provide 80MHz clock. It will work in a burst mode - sampling 288 measurements x 16 bits at 5MHz.I can't decide whether I ...
