Hello Everyone,Right now i am facing the issue on detection USB.I am attaching snap shots of the my USB configuration.USB port not shown after powering up the board. i am doing some basic thing like on receiving via USB in RX interrupt function of US...
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...
