CAN Communication b/w STM32F753Z8 and Arduino Board

Hello Everyone,I have a two arduino boards communicating with each other on a CAN Bus. Arduino is connected to CAN Bus via MCP2515 .Both arduino are communicating correctly with each other. Here is an example of my transmitter on arduino:/**********...

FLASH memory map

hello I have a stm32f030c8t6 which I wish to save some data in its FLASH memory. I use Address Page30 which is 0x08007800 in memory map. it is in 7th Sector. I've developed my code and easily saved some data in that Address. recently I tried to add s...

Enabling SWO for Nucleo-L452RE-P

I can't seem to get my L452RE-P board outputting on SWO at all in an empty project. The solder bridge is closed by default, so I don't think it is that. I'm using this code here but it doesn't seem to work at all:void swoInit (uint32_t portMask, uint...

32F417: Any way to make an SPI SRAM to look like normal RAM?

What I am after is trapping an invalid address access e.g. at 0x30000000 and reading or writing 4 bytes from an SPI SRAM.The invalid address trap does trap the access but do you get the address you attempted to access and (if writing) the data word?I...

Hello, can anybody tell me the maximum allowed voltage flowing into STM32 when in Open-Drain-mode on an STM32G030F6? The datasheet does not show any overvoltage protection diodes, so I am wondering if it is possible to sink 12V limited to 50µA?

The concrete use case is that I want to control a p-channel-MOSFET which gate is pulled up to 12V via an external 10kOhm resistor.To switch the MOSFET I have to pull the gate down to GND, so I thought about using Open-Drain-output mode to let the 12V...

STM32H743VIT6. FMC for SDRAM

Hi,Is SDRAM over FMC supported in STM32H743VIT6 MCUs? I can't see this option in CubeMX, only NOR Flash/PSRAM/SRAM/ROM/LCD and NAND Flash. The datasheet says that SDRAM is not supported in LQFP144 packages, but my one is LQFP100.Looking forward for a...
