Hello, I have a question about STM32H7S3A8I6 MCU.https://www.st.com/resource/en/application_note/an5935-getting-started-with-stm32h7rx7sx-mcus-hardware-development-stmicroelectronics.pdfLooking at Table 2 of the description in the PDF above, for gra...
Question moved from this post. If I have two devices on the same PCB. say an F7 and an MP157, can the CAN_TX of one be connected to the CAN_RX or the other without a CAN transceiver? Similar to UARTs on the same PCB. Maybe series resistors would be r...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
Hello there,I'm trying to create a project for stm32h7s7 with external loader. But when i added the external loader in IOC file the all indexes were lost in editor mode. But I checked for building, i can't see any problem. I tried index -> rebuild bu...
Hello, What can i take for a MCU which has function with Low Speed USB 1.1 ? I must make a USB HID Interface as Gamecontroller. It is essential to prevent the PC from getting stuck on the USB port, and this is only possible with USB 1.1. greets Ste...
Hi, I have an application with 4 legs PFC and 2 legs inverter controlled by the STM32G484VET3. Can I use one input to disable both when a fault happens independently from the software? Thank you.
Hi,is there a 64Kb drop-in replacement for the STM32C031G6U6 (which is only 32kb)?We need to find a part where - ideally - we just use the same code without any mods, this is the most important part.And is there perhaps a tool that helps with that? O...
I'm currently using the DCMIPP Pipe 0 to dump RAW10 straight into memory for outside consumption. The documentation I can find tells me that this pipe will unpack the packed 10-bit RAW data, and store it in 16 bit unsigned format. 2 bits per pixel. T...
Hello, I have tried a number of I2C slave tutorials found on YouTube with no success, but none are specifically for the STM32G03 series. Also I am getting a very strange phenomenon. In CubeMX for I2C2 I set the first slave address to 0x012. On my PC ...
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
