Writing SPI driver for digital potentiometer issue with LSB/MSB order

Hello. I have AD5270 10 bit digital potentiometer and I am writing SPI driver for it.The wiring is as following:STM32F407 AD5270+3.3V ->VDDGND ->VSSSPI1_MISO -> (Not currently wired with SDO, SDO is pulled up with 10k)SPI1_MOSI -> DINSPI1_CLK -> SCLK...

Dual Port SRAM corrupted unless read after write

I have a custom board with an stm32f733zet6 and an stlink-v3mods as a programmer/debugger.Attached is a CY7C006A-20 dual port static ram which asynchronous and I'm using it without wait. I'm running 216MHz off HSI + PLLCLKI've set timing values of 1...

Framing error callback with dma uart channel

Hi. I have an uart managed by dma rx channel.In order to disable the error callback when a framing error comes (HAL_UART_ERROR_FE) I have comment out the line of codehuart->ErrorCode |= HAL_UART_ERROR_FE;Is there a grace way to do that, without to ed...

A problem in switching the same ADC with different channels

Hi, My purpose is to use the same ADC with different channels (one after another). I use stm32G4 with 170MHz clock speed. I want to check ADC values within a short time period. I use Baremetal. But unfortunately, I can only read one channel. it is no...

Why does RCC_APB1ENR:TIM2_EN get cleared in Stop Mode when DBGMCU is set?

We noticed that our TIM2 did not count after our STM32L152 went to Stop Mode and woke up again.When we analyzed the problem, we found that our debug probe set DBGMCU to DBG_STANDBY | DBG_STOP | DBG_SLEEP. When we power cycled the µC or set DBGMCU to ...

How many manufacturing heat cycles can DSP device STM32F107VCH6 withstand before it functionality/quality is compromised?

Hi, We are using DSP device STM32F107VCH6 and would like to know how many heat cycles the chip can withstand before its operation is compromised, by heat cycles we mean surface mount reflow cycles and any subsequent removal for rework / component sal...
