I think I am in the wrong place
can anybody tell me how to get in the Black Pill fourum ?

FSMC_NOE and FSMC_NWE confliction with FSMC external NOR/SRAM read operation
Hi Team,STM32F407 running on STM32F4xx_DSP_StdPeriph_Lib_V1.8.0 with the following init configuration,void USBFIFO_FSMCConfig(void){ FSMC_NORSRAMInitTypeDef FSMC_NORSRAMInitStructure; FSMC_NORSRAMTimingInitTypeDef p; p.FSMC_AddressSetupTime = 0X00;/...
Hello, I have been working with a STM32F4 where I use two channels of TIM8 to trigger data transfers from two GPIO ports to memory using two DMA2 streams. I would like to have these DMA streams write 16-bit data interleaved to 32-bit memory addresses.
I have gotten the 16-bit data transfers individually working where each DMA stream would write to memory in half-world fashion. For this application it would make more sense to write 16-bit data from GPIO port I to the lower half of a 32-bit word and...
STM32 QSPI Bank1 and Bank 2 usage
Hi All,We are planning to use STM's STM32H750VB in our design.We need 1 QSPI port from the MCU.We saw in the reference manual following 2 things: 1. In block diagrams (page 883) it is mentioned as if we can enable dual-flash mode (8 bits) and disable...
DMA underrun and overrun
Hello, Thanks for wonderful support I am working on STM32F407X mcu DMA program and want to understand when will DMA underrun and overrun happens. This is not explained in any of the ST documents even though the RM mentions this>>>>>>>>>When burst tra...
What is the pin overlap between the Nucleo's Morpho connectors and ZIO connectors?
I'm using the Nucleo H743ZI2 right now and have mostly just been using the pins accessible through the ZIO connectors (CN7, CN8, CN9, CN10). I'm wondering about the main purpose of the Morpho connectors (CN11 and CN12). I've noticed most of the Morph...
What is the procedure to setup Uart Transmission in One shot mode with a DMA?
Hi guys, for some reason I can't this working for the life of me.I am trying to implement a DMA with Uart Transmission with a one shot, reason being is that I noticed with the DMA on circular mode it just transfers whatever is in the buffer even ther...
Resolved! Hello I am using STM3F205VF microcontroller. I want to print hello world. I followed the following steps. I am encountering following errors.
The steps that I followed :1. Configured micrcontroller added UART Rx, UART Tx and Serial wire Viewer 2. In main.c in the infinite while loop added (HAL_UART_Transmit(&huart2, "HELLOWORLD ", 12, 100) ../Core/Src/main.c:100:35: warning: pointer targe...
Probleme on generating code for Dual Core STM32h MCU on CubeMX
Hi,I have a problem to generate a code for MKD or IAR EWARM on CubeMX.I have a NUCLEO-H755ZI-Q development board.I can generate the code for others MCU or Nucleo Botrads, but i have seen that this problem is only related to any MCU with dual core lik...
STM32F745 SPI compatibility with exteranl ADC LTC1403A and AD7274
Dear All,I am working on a new design with STM32F745 and an external ADC of 2-3 Msps range.I have two ADCs candidates: LTC1403A (14 bits/2.8Msps/SPI) and AD7274 (12bits/3Msps/SPI). Please find attached datasheet for your reference.The maximun SPI fre...
