NUCLEO-L073RZ, ADC reading problem on PA2 and PA3 pins We removed SB13 and SB14 resistors on NUCLEO-L073RZ board and configured PA2 and PA3 as ADC channels (in CubeMX), but AP2 and PA3 don't read any analogy inputs.

We also configured the other PAx pins, such as PA0, PA1, PA4, PA5, ect as ADC channels. these pins work properly.Removing SB13 and SB14 is based on the suggestion of NUCLEO-L073RZ manual (UM1724 Rev 14), in order to use PA2/3 pins.Please let us know ...

Question about MCU STM32G474RET6, SPI peripheral doesnt work well in 42.5MHz or more

Hello ST Team !I would like to ask you a technical question about the STM32G474RETx controller, SPI peripheral.I'm trying to configure 2 MCU's (master & slave) as follow:- SPI1 in Full-Duplex mode, 16bit data width- Master SYSCLK: 170MHz, SPI clock: ...

Can I write to a UART Data Register if the RXNE bit is set(data has been received in the RDR but not read yet) ?

I want to use the WM8994 on the STM32F769-DISCO for 24 bit acquisition on the Line In connector. Unfortunately the BSP code is fixed at 16 bit. :-(

Has anyone done the changes necessary to switch up to 24/32 bit acquisition. It seems like its just AIF1_Control[6,5] on the WM8994 but the SAI is a complex beast and I'm not having a lot of luck. Any pointers would be greatly appreciated.

DMA HALFWORD and SAI_DATASIZE_24;

Posted on June 29, 2018 at 07:30Hi, I'm trying to use SAI_DATASIZE_24; with the Audio_playback_and_record application demo for the STM32f769i_Discovery.The demo uses DMA to copy data from the SAIx to the recorder buffer in 16bit.I tried changing the...

Getting elapsed time after stop mode

Hello,I am looking for help. I am using stm32L0. The problem is as follows:ST goes in stop mode for example 5 seconds. After 2 second some interrupt wakes the ST. Then I want go in stop mode for the remaining time which in this case is 3 seconds. Is ...

union type structure memory

I have some old program to migrate to stm32h7. the old program is written by 16 bit mcu. so it is easy to implement union structure and easy to copy structure from memory to another; however, in stm32h7, this is 32 bit mcu, so memory size is 32 bit, ...
