Why are there no low layers drivers for quad SPI?

I have absolutely no problem with working with the registers, but we now have inconsistent use of low layer drivers and accessing the registers directly in my team's code base.

How to write a uint16_t array to flash memory for STM32L053 which only supports word write

HiI am able to erase two pages (my array is length 256 ), now I want to write my array to a particular memory location.Here set is the address which is 0x080E0000p_source is my uint16_t array which I want to write to flash. And length is 256.How do I...

STM32L4 ADC does not stop

Hello,According to the Reference Manual of the STM32L431 controller, the ADSTP in the ADC_CR register must be set to 1 to stop the ADC. Additional condition is that both ADSTART=1 and ADDIS=0 must be. Once the ADC is stopped, the ADSTP bit is cleared...

Can the temperature of reflow soldering affect the programmed data on a device?

The device in question is a STM32F030F4P6. I want to know if there is any risk of programming a device before sending it through a reflow oven (lead free soldering temperatures). We do this on other devices without issue, but I'm not certain if this ...

Resolved! Differences between DMA call back and Interrupt call back (SPI, UART, etc)

If I want to do some communication using SPI or UART, there are options like DMA or Interrupt, both of which give me callback. That means after MCU issues or start Tx/Rx function, it is free to do something else while waiting for the Tx/Rx complete c...

SPİ SCK frequency ?

hello , I use spi and ı use slave mod spi. When I send a frequency of 500khz or more as a clock so data is shifting or I recieve wrong data but I send a frequency less than 500 khz I recieve true data. what is the reason of this.( use stm32h743z...

Writing to array to flash memory which is uint16_t. I am using a STM32L053 nucleo. My program gets a hard fault error.

This is the how I'm trying to write to flashBasically I pass my uint16_t array to a function called FLASH_WriteA which accepts the array, the destination array or the location and the lengthvoid FLASH_WriteA(uint16_t * src, uint16_t * dest, uint16_t ...

Resolved! STM32L4R: How do Flash Option DBANK and DB1M interacts?

In FLASH_OPTR, both DBANK and DB1M are r/w and have no restrictions beside that PCROPA/B needs to be disabled. For 1M device there are two(?) sensible settings DBANK=1, DB1M = 1 for 1Myte dual bank continous modeDBANK=0, DB1M = 0 for 1Myte single ban...

Resolved! STM32F051 TIM6 "basic" - more registers defined in STM32F051x8.h than RM0091 TIM6 section

Beginning to explore timers in STM32F051 (from DiscoveryF0). I'm starting with TIM6 (basic timer) as I'm looking for nothing more than a periodic interrupt. Before I get started, I'm wrestling with where to find complete register reference for the co...

Implement Cordic of Arctan2 through ADC and DMA

I need to calculate angle value with input of sin/cos from ADC1/ADC2 channel by DMA way. As using the cordic of atan2 function,I think that two parameters of Y and X need to be written to pInBuff as like the key code below, is it correct? sCordicConf...
