关于DCMI接收数据的问题
我公司有一款芯片，它使用DCMI输出数据，但是又不是标准的DCMI接口，它没有行同步信号，只有一个垂直同步信号，请问有哪款芯片可以接收这样的数据？如果有，请给出具体的芯片型号和具体的代码示例。

Unwanted received byte with UART+DMA
Hello ST experts,I have a weird experience with UART communication between two STM32G4 microcontrollers. MCU1 sends 10 bytes to MCU2 via UART. Both UARTS are configured with 9600 Baud rate with DMA in circular mode. The Problem arises when the MCU1 i...

STM32WB09 Reference Manual & Datasheet Disagree on GPIO Alt Functions
In the STM32WB09's Reference Manual, RM0505 Rev 3, Table 8: PA10 and PA11 have SWD modes for their AF4.However, in the STM32WB09 datasheet, DS14210 Rev 6, Table 6 and Table 7: PA10 and PA11 have no AF4. Which one is correct?
Resolved! STM32U5+SPI+GPDMA - cannot get simple loop-back data working
Using Nucleo-U545RE-Q, SPI2 Full-duplex Master, default GPIO selected by STM32CubeMX v6.15.0 with LL selected for implementation.Config clock for max 160 MHz and prescale SPI by 8 for 20 Mbps. Add GPDMA Ch2/3 for SPI2 TX/RX.I double checked the outpu...
STM32L031C6 reading vdda & temperature
Hi,I have a custom board with an STM32L031C6 and I'm trying to read the internal temperature. The board is battery powered at about 2.6V and the vdda is the same.If I read the ADC channel with vrefint, it returns a value of about 850, which, when pas...
STM32G4 Half-Duplex Slave early Complete Callback
Hi, I am using STM32G474RE. I try to read out LTC2440 with the SPI interface. I have configured the LTC2440 as SPI master (In its datasheet the mode of operation is specified as Internal SCK, 2-Wire I/O, Continuous Conversion). The LTC2440 provides a...
SGONAK does not trigger global OUT NAK status in RxFIFO or GONAKEFF interrupt
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
FD-CAN - Protocol Error - ACK Error
Hello, We are facing an intermittent CAN-FD issue in the field and would appreciate guidance from the community. Our system has two devices on the bus (no other device on the bus) using a request–response architecture. The master sends a request ever...
SPI and a synchronized Control/Data line for a display controller
I'm trying to drive a display controller and have found it trickier than I anticipated, and I hope you can kindly help. My microcontroller is the STM32U545. My display controller is the UltraChip UC1628c_A, as part of a custom 160x160 monochrome LCD....
