Hi! all experts in Community ST,I have been working on the embedded flash memory of STM32G474RE and the whole programming process of the flash memory has been successful.However, I do not understand how the Error Correction Code works.Referring to th...

Hi all,I am currently trying to implement ADC Oversampling so I can get 16-bit resolution of ADC result rather than 12-bit.the dual simultaneous mode is used for ADC, ADC1 and ADC2 conversion, and the following is my STM32CubeIDE Setup: ADC1 Ch 6 and...

Hi, I always appreciate all members here for helping beginners like me :)I am currently working on a project using Timer and ADC+SPI with DMA.The main timer loop is running at 40kHz, and this frequency should be strictly guaranteed.Two DMA process...

I am working on a project using UART communication and I have a question what is really different between interrupt mode and DMA mode in TX except for their underlying mechanism.(HAL_UART_Transmit_IT vs HAL_UART_Transmit_DMA)I know DMA uses the DMA c...

Thank you! I am finally able to move forward :))By the way, shouldn't the ECC data be in the flash memory somehow? how can they be invisible although I can access almost every memory address?I cant find any mention about that in the reference manual ...

Hi Philippe!thank you so much!I am confused the naming, the number of conversion which can be set 1 to 16 in the cubeide configurator. you can find it in the image above.Is Conversion(tn) in the equation above the conversion result of t0 to t(N-1)? w...

You are right. I am even not sure what I should ask. :( speaking of the setting, I am wodering if the number of conversion shouldnt 1 since the conversion results will be summed from the first (n=0) to the end(n = Number of conversion -1) and N shoul...

yes i got 16 bits result, but it seemed not right. is the cubeide setting correct? looks only 16 times of single conversion..?

Hi all,I have a little progress, thanks to TDK and waclawek.jan!The concept which like the diagram I posted, works fine now.SPI via DMA is simple but ADC was kind of a headache for me.Few things I have learned:as waclawek.jan said, I was trying to c...
