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...
Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
I have seen that it takes about 28 ticks to read registers, so I think my stm32h750 runs really at 17Mhz, it seems is not risk, so perhaps it exists another more fast stm32 micro that have more 17 MIPS
This is a pretty basic question but I would like a bit of clarity if possible.If a GPIO pin is configured for the fsbl code can it also be used in the Appli code?If so how would you go about defining it in the Appli code? There doesn't seem to be an ...
Our company has a chip that outputs data via DCMI, though it does not employ a standard DCMI interface. It lacks a horizontal synchronisation signal, possessing only a vertical synchronisation signal. Could you advise which chips are capable of recei...
Hello Expert, Could you please provide guidance on the issue below? We are using the following setup:- MCU: STM32G0B1CCTx- Software: X-CUBE-TCPP 4.2.0 with USBPD Application 4.2.0 Dual Role- Board Part: TCPP0203 v1.2.3 We are developing a USB PD boa...
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...
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...
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...
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....
