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 ...
The datasheet for STM32H573 (WLCSP80 package, rev 5 p. 251) says that the leftmost ball (in the bottom view on the datasheet) is F=0.384mm from the package edge. Horizontal ball pitch is 0.35mm*(1/2)*√3. Therefore centering the ball array horizontall...
Hi,I’m working with the NUCLEO-H723ZG board and would like to know if it’s possible to use its two DAC outputs to generate a differential signal.Thank you very much
Hello again :)I have used all ideas including chat GPT. I can't see any changes in I2C line with oscilloscope. STM32G0B1KBU3N have Pin PB9 as SDA and PA9 as SLC. 3.3Volts pull up via 4.7 kOhm resistor. I am trying negotiate with LM51772 DC-DC buck-bo...
Hi,I am searching for the external loader to flash the h750 discovery board. Can you please help me?Best regards,Andrew
Split from this thread.Hi there, switching to USART3 didn't work. I still don't see any messages in the serial console. the second time I try to connect to the serial console gives this error.
