Hi Support Forum,I am using STM32H743ZI part with SDIO configured as Master and connected to SDIO slave which is a Wi-Fi module.In this case high speed bidirectional data transfer happening Tx -20Mbps while Rx with 1024bytes/sec.As soon as data tran...
RTC used the LSE with 32768Hz oscillator and is configured for this option.While DBP bit is set RTC counter is stopped . Is it true or false?
Dear all,I hope I can receive som help from you. I'm struggling since a couple of days with SAI2 block A on the mentionned MCU.I am using STM32CubeIDE and I have configured it using HAL library in master mode with MCLK output.When I try to send some ...
I am currently working on controlling a digital potentiometer using i2c with the STM32f303Ze. According to the datasheet of the DigiPot you can send different bits to make adjustments. after a lot of trial and error the voltage still didn't change.co...
HelloI want to write to FLASH variable uint32_t time at power off. Which signal to use for this? greetingsAndrzej
I have a stm32f427 with 1Mx16 external SRAM and SDMMC.I am reading the SDMMC by DMA into the SRAM in two blocks of 512 bytes into a 1024 byte buffer.The SRAM is mapped from 0x64000000 - 0x641fffff. Address and data are not multiplexedI have now disco...
I need to send data one byte at a time via SPI. After transferring the byte, I set "Chip Select" from the program to state 1. I track the end of the transfer by the BSY bit in the SPI_SR register. But the microcontroller transmits two bytes, the firs...
I want to read registers of BQ40Z50 IC. Its using SMBus for tranceive data. But I need to speak with it using I2C. I use STM32F072 -> I2C2. It doesnt support SMBus-interface, but SMB is based on I2C.I havnt posibility to connect that IC to I2C1. We c...
Hi, From the st.com website/microcontrollers most of the links from the main page result in a "403 error" when clicking on the links to the various micros (See image below)This is an example link that is currently returning a 403 error. Any idea wha...
