Hi Guys, I'll be purchasing a few STM32H753's in a week or two.Can someone please tell me where to find info on the fastest clock rate the GPIO pins can run at. In the reference manual I can only see in GPIOx_OSPEEDR register these settings:00: Low S...
Developing on an STM32F417ZGI have configured PE2 as a rising edge interrupt. It is the only pin 2 set as an interrupt the others are configured as follows:PA2: ETH_MDIOPB2: Input pull-downPC2: ADC1_IN12 (No analog watchdog)PD2: OutputPF2: Input pull...

Hi I have ADAU1978 which is a quad ADC that gives I2S data which im trying to store in a SD card under .wav extension. When i do this i get a .wav file of size 8kB. When i try to play it with windows media player, it doesnt throw any error,but doesnt...
Hi,I've read that for some STM families (F0, F3, L0, L4, etc.) the I2C clock timing must be calculated with an excel file or with the STMCubeMX software.The calculus is "closed source"? Can I reproduce it in my own code?I'm writing an interface for a...
I am working with STM32F411/13 controllers from ST. And i observe an issue with SPI reads if i-cache is enabled. More details as below:I do have the FLASH PRE-FETCH enable set. And Flash wait states properly configured based on the System clock.And a...
I am trying to protect code(in flash) and data(sram) using fire wall feature But board is resetting when exucute the function. Following is the code to initiate and enable fire wall. void firewall_init(void){ FIREWALL_InitTypeDef firewall1; firewall1...
Hi,As far as I remember, I've read something about that a while back. I was wondering if I can send data to a memory-mapped device (FSMC/FMC) in a continuous loop a byte per iteration using the DMA peripheral. Thanks
