low lever driver backup sram example

Is there an LL example to enable the backup ram. This doesn't work:    // Enable PWR clock   LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_PWR);   // Enable Backup ram clock   LL_APB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_BKPSRAM);   LL_APB1_GRP1_Enabl...

Resolved! STM32L475VGT6 ADC values getting stuck during ESD testing

During ESD testing, we are noticing issues with our ADC values getting stuck.We are using STM32L475VGT6.No permanent damage has been observed. Resetting the MCU always results in normal behavior.  We are using DMA to load all ADC channels.  We are ca...

Does DMA miss data while it is used by SAI interface?

Hi everyone,I work on Data Acquisition System project. Our main controller is STM32F765VG. We used ADS131A0x A/D converter (by SPI) to sample input signal in our previous version. Now we want to replace ADS131A0x with ADS1274 (because of its higher s...

Using STM32 to replace old peripheral chip but it needs 8-bit parallel data bus to communicate with the Core like 8051

Can STM32 able to replace an old peripheral that required 8-bit parallel data bus and communicate between 8051 MCU. We can't modify the 8051 MCU and we can't use FPGA too. I know FSMC is very close solution to my case but in my situation, the STM32 i...

Resolved! GPIO pin does not stay high

Hi everyone,I am trying to use CubeMX and the HAL library to get two STM32F411E discovery boards to communicate with each other via SPI. In a first step I am simply trying to configure the master correctly. I want to drive the NSS pin of the slave wi...

Resolved! STM32L43KC: Changing Clock Frequency?

Hey guys, just having the hardest of times changing clock frequency to 80MHz for the system clock and 43MHz for the ADC clock. Every time I try it seems the writing function to registers gets disabled such as RCC->AHB2ENR trying to enable GPIOA and A...
