Giving an example for my question. For STM32H563, for freq. 140MHz, it is possible to use three different configurations:- 4 WS, VOS2- 4 WS, VOS1- 3 WS, VOS0If I want to optimize for power, I should choose 4WS VOS2. If I want to optimize for performa...
I'm trying to migrate my Azure IoT application from a BG96 to a BG95-M3, both from Quectel. I have solved some problem due to the difference in use of the uart3 pins of the BG96 and BG95. Should I make more modifications to the software? Is there a d...
Good evening,I am trying to sample various signals at different frequencies with adc in dma. Changing the size of the acquisition buffer seems inefficient, so I opted to change the clock prescalers, but it's giving me problems (I guess on changing th...
They are defined like this in stm32h563xx.h:/*Buffer Descriptor Mask*/ #define USB_PMA_TXBD_ADDMSK (0xFFFF0000UL) #define USB_PMA_TXBD_COUNTMSK (0x0000FFFFUL) #define USB_PMA_RXBD_ADDMSK ...
I am struggeling with a HyperRAM on STM32H7A3 with OctoSPI2 in Memory Mapped Mode Write.In order to check, if the access to the HyperRAM is ok, I am running through a loop which writes all 0 / 0x55555555 / 0xAAAAAAAA (with 32 Bit access) to the RAM a...
I am trying to increase FCLK, and I changed the voltage scaling to VOS0, and configured the PLL1 for 240 MHz (src=HSI (HSIDIV=2), M=2, N=30, P=2), but it did not boot (it freezes when a change the system clock mux to PLL1). I realized when I decrease...
Our product uses an STM32L562VET6Q MCU. We are using an ADC to measure current via a 1ohm resistor. Because the currents are relatively small, I want to use the internal opamp in PGA mode to double the input signal before it is send to the ADC. I ...
Hello,I have a STM32F407 Discovery Board. I am trying out the FatFs_USBDisk demo application. I am running the application from STM32CubeIDE.When I run the application and plug in a USB flash drive, the demo application works as expected. I see the S...
Hi I like to find out How i can start a spi communication with DMA by a timer i tried to search a lot on google for this but didnt found any solution for the SPL and a F4.My Problem is i try to read out a ADC connected to SPI 1 very fast first i trie...
What is the analog bandwidth of the stm32 ADCs in the different series?
