Hi!I use the RTC of a STM32G030K6T. It is clocked by LSI (appr. 32kHz). And PREDIV_A is 0x0 and PREDIV_S is 0x7FFF. So I expect that RTC_SSR overflows every 1.024sec...But: It overflows every 0.687sec... As if the LSI frequency would be 47712Hz...I m...
When I use sleep mode while debug it sleep mode Works. But when I try runing code without using debug method it dosnot go in Sleep mode. When I chack current.When using debug method stape by stape. Without using stape by stape debug method.Hear is t...
Hi I m using SPI DMA on H7 series, and notice under SPIx_TX and SPIx_RX there are at least 14 DMA channels to choose from, i.e DMA1 Stream 0-7 and DMA2 0-7. Can i select these "channel" randomly or is there a reference manual that state otherwise? L...
I want to know the reliability data for M41T0M6F.so please provide to me soon. thank you
Is STM32F446MEY6MTR of MIL grade microcontroller? Is any variant of STM32F446xx have MIL 464/461 or MIL810G standard?
Hey everyone, I'm learning about USB CDC and soon USB HID. I think I successfully program the stm32 as a cdc device because I can connect to it, and I can read and write serial commands through a terminal. I can even catch the serial buffer through t...
I used STM32H563 transmit a message through I3C CCC direct.I create a new CCC command "0xA0".Control send the command to target.But target will enter HAL_I3C_ER_IRQHandlerUesd the general command "0x89".The target can receive this command. The Buffer...
Does anybody have an example code how to use SAI in STM32U5A5 as PDM interface?I use STM32U5A5, with LQFP64 package. So, I understand from datasheet: the SAI (I have just SAI1 available om pins), supports PDM interface (for MEMS MICs). My package has...
Hi,everyone! I want to know if FDCAN ( I'm using STM32H7) has lost the automatic Bus-off Recovery mechanism. Looking Forward to get your reply.Thanks!
I have an STM32WB55CGU6 on a custom board with a 32MHz HSE. I'm using low power uart1 with PA2 & PA3 pins. My settings for it are: - baud rate 9600- word length 8 bits- 1 stop bit- parity noneIt won't transmit. Cube doesn't receive it, any terminal ...
