Hi,I wanted to send hexadecimal numbers through UART. I am using STM32F405. Can it be done.If I am sending float number as 1.3456 string (text) to windows COM port to english language windows application field. If for example regional settings being...
Hi, I'm using a STM32G07x1 that will need to receive firmware updates from an embedded Linux CPU. The only connection between these devices is an I2C bus so I plan to use the ROM I2C bootloader to handle updates.I am aware of AN4221 that describes ho...
Hello,I'm trying to use DMA with an Usart to receive incoming data in a circular buffer. Basically this is my code for configuration using UART5. I can send data, so i assume, that port und clock configuration is correct. When receiving data, NDTR is...
Hello I am in the task of adding a new flash as an external flash via QSPI interface with the MCU STM32F777ZITx.The flash that I want to add is S25FL256L as an external flash. I am not finding any references which I can use with this flash. Also it i...
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...
