RM 0456 10.5.4 Dynamic voltage scaling management writes under "System frequency steps on STM32U59x/5Ax/5Fx/5Gx device"===On STM32U59x/5Ax/5Fx/5Gx devices only, the maximum system frequency increase ordecrease in the VOS range 1 is 80 MHz.===This is ...
Hi developers, I'm new to STM32 MCU, but recently need to use it for a automotive Ethernet board design. The ethernet PHY I am going to use supports the jumbo frame up to 16kByte. Do anyone happen to know if STM32F407VGT6 can also support this jumb...
I'm trying to read and write SPI bytes from an STM32F446RE chip with DMA. The STM32f4 is the slave and a RPi is the master. The first SPI read works fine (data read into buffer starting at index 0), but subsequent reads have the data starting at in...
Hello everyone,I just started using stm32cubeide. I'm trying to do I2S protocol.I'm trying to filter using the MP45DT02 microphone on my card and get noise-free sound as it is to the speaker on the MAX98357A Amplifier card. When I checked my connecti...
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...
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...
