I have an 8 bit(Parallel data) ADC output of frequency 50MHz. At this frequency, I tried to store 1400 bytes of data on STM32F446RE but failed. According to its specification sheet, GPIO ports can support till 180MHz. Could you tell what is the rea...
After the firmware is up and running, I am trying to put the SDRAM in self-refresh mode. We are using FreeRTOS. In order to put SDRAM into self-refresh mode, I write 0x4480D to FMC_SDCMR register. I am using IAR debugger, and I execute the statement...
Hello, I am very new to STM32 MCUs and hoping someone can explain to me the HardFault_Handler and possible reasons why my code is jumping to here? If there is a good resource which discusses this, that would also be very useful but I haven't been abl...
Need 10 samples for a new product prototype. PCBs on the way now. None available in distribution. Can you help?Thanks - Duncan
Hello,I want to use MDMA on STM32H7 to copy data from ADC to DTCM RAM. But it is not clear to me how to set it up . From ref manual I asume that there is a connection with "standard DMA" DMA1 or DMA2, maybe I have to set up a channel there to, but th...
I am using STM32F072RB and I have interfaced it with NRF24L01 module.I have refer the library files attached below for nrf24l01 module.I am trying to send string "Hello World" from one module to another. .Transmission found ok, but at receiving side ...
Hello, i try to program my dwm1000. I am new on that. At the first step i send 0x00 to take the ID verification (0xDECA1000) but its not constant at the same value. Some times is 0xDECA1000 with the same code. Some times i take 0xDC8A0330 or somethin...
Is there a way to self reset other than watchdog?Without external pull-up resistanceI want to keep the GPIO high even if the MCU performs a soft reset.Is there any way?
Is there anyway we can decrease this time. We are using void DMA2_Channel2_IRQHandler(void) and void DMA2_Channel1_IRQHandler(void). Both RX and Tx callbacks are not firing and really not able to debug this issue. Looking forward to a solution. ...
