Trying to change modes on GPIO pin from input w/EXTI to timer capture. It appears to change modes, but will not capture timer. Any advice?

HAL_GPIO_DeInit(GPIOA, GPIO_PIN_7); //PA7 is no longer GPIO interrupt sourceHere is my code to go into timer mode:/*ReConfigure GPIO pin : PtPin */  GPIO_InitStruct.Pin = Vib_In_Pin;  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;  GPIO_InitStruct.Pull ...

I have tried a lot of ADC DMA examples, but I don't know where I am failing. I am using a MIKROE card STM32F407VGT6, the result of the DMA register in DataADC comes in only two states (1048 - 0V and 4095 - 3V3)

Here is the code of what i am doing, certainly I am still confused where do I have to change the register. #include "main.h"     /* Private variables ---------------------------------------------------------*/ ADC_HandleTypeDef hadc1; DMA_HandleTypeD...

Hi, We use a STM32F469 and we would like to add 2x512Mbits of NOR FLASH and 128Mbits of SDRAM. Is ST micro recommand some Part Number for FLASH and SDRAM components ? I have not seen any application note. Thanks

The STM32469I-EVAL has 128Mbits NOR FLASH (PN: S29GL128S90FHI0) and 128 Mbits SDRAM (PN : IS42S32800G-6BLI).There is 512Mbits FLASH version of the S29GL family but the access time is higher. Is it an issue for the STM32F469 ?Which requirements have I...

strange debug ROM table entries

Hello,I am looking into the ROM tables on STM32F439ZI. TPIU (0xE0040000) class type is 0x9, in its romtable, there are two entries:0xb, which is strange because it is marked as present (0b11) but offset is zero which is prohibited.0x1, which means pr...

X-NUCLEO-NFC05A1 NFC Poller: "Error: writing interrupt pin to gpio export file" on Raspbian Lite

Hi,i'm unable to run the NFC poller on a X-NUCLEO-NFC05A1 on a raspberry running Raspbian Lite.I get the following error:"Error: writing interrupt pin to gpio export file"Could someone advise please?Jacopo Chicco

Hi, i am working on stm32f429zit6 discovery board, can i get an example code for ADC, to collect samples in an array, using TIMERS and DMA.

Manipulating MCU SPI Interface to Access a Nonstandard SPI

HI There,I want to access multiple SPI slaves at the same time.They all share the same CLK , the same MOSI pin and the same CS.Therefore, I wrote two code sections which basically should do the same.They kind of work, but they both have the same Prob...
