Hello, I use STM32F469I-DISCO-REV-AU1 and want to connect RTC DS3231 as my external clock. I am trying to connect. I tried to connect using I2C but couldn't get any response on the screen after this. Can anyone help me with this?

Is an unaligned 32 bit read/write with FMC to 16 bit SDRAM possible?

We want to use external 16 bit SDRAM for heap and stack. The SDRAM is configured with byte enable and MPU. I tried to map the memory to 0xC0000000 and 0x60000000, but it doesn't matter. Also the configuration of MPU with MPU_TEX_LEVEL0 or MPU_TEX_LEV...

STM32H730 FDCAN TxDelayCompensation

I use FDCAN in STM32H730 for communication over CAN-FD.At the moment it works with 500kBit/2000kBit without TxDelayCompensation. But we want to communicate with 1000kBit/4000kBit too. Therefore I want to enable TxDelayCompensation.I'm not sure how I ...

STM32C031: No RTC SubSecond alarm interrupt, but works on calendar type alarms

RTC SubSecond does not generate an interrupt with an STM32C031.Interrupt works perfectly on calendar type alarms.I work in LSE at 32768KHz, divider 127 and 255 RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0};...
