Nucleo H723ZG docking options

Hello,I want to use the Nucleo H723ZG for a project with analog & digital lines and can't find the article number of the headers CN7, CN8, CN9, CN10. Is there a specific cable/contact type I can use to plug in the black header body? Or are the header...

According to AN4488 for STM32F4 (64-pin in my case), the VDDA pin "must" be connected to two decoupling capacitors. Is this needed for digital-only applications? If not, should the pins be left floating? The ADC seems isolated from the rest of the supply.

Resolved! stm32u585 clock config

Dear Sir.Attached a code of SystemClock_Config();void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Configure the main internal regulator output voltage */ if (...

VREF+ not working

Dear Sir.Attached a schematic of STM32U585 . LDO_V28 is tested for 2.8v.Issuing the commandHAL_SYSCFG_VREFBUF_HighImpedanceConfig(SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE); HAL_SYSCFG_VREFBUF_VoltageScalingConfig(SYSCFG_VREFBUF_VOLTAGE_SCALE2); HAL...

Value gaps in DMA transferred ADC data

Setup is as follows:ADC1 & 2 in 'Dual regular simultaneous mode only'DMA1 stream 0 used to transfer ADC data to AXI SRAM buffer (40000 32 bit values), DMA circular mode.Using 'HAL_ADC_ConvHalfCpltCallback' to signal half buffer filled and 'HAL_ADC_Co...

Inter-channel interference occurs when reading multi-channel adc.

hellow.I tried to read multiple adc using stm32h743, but I had great difficulty due to inter-channel interference.I tried to read multiple adc using a simpler "NECTULEO-L073RZ" to find out what the problem was, but the same problem occurred.Please he...

Se puede alimentar STM32F103C8T6 por USB a través del ST-LINK V2, mientras el Hardware (SENSOR) está alimentado con una fuente externa? La idea es visualizar mediciones del ADC1 con CubeMonitor desde la PC.

Resolved! What can be giving incorrect ADC readings when transferring code from Nucleo to PCBA?

I've been working on some code to control a 4-wire touchscreen on DisplayTech's DT028BTFT-TS using timers to de-bounce the respective touch screen wires.The code works on the Nucleo-F413ZH under debug and standalone. The coordinates of the positioned...

Struggling finding electrical peripherals interconnection information for STM32F469...

Hello, I am struggling finding electrical peripherals interconnection information for STM32F469. Peripherals are not covered in the datasheet, and I have looked thru Application Notes to best of my ability. Is there a document I missed that goes over...

Resolved! Did I destroy my STM32F7? (SB12 removal)

Dev board: Nucleo-F767ZIDear all,as I wanted to have my own Vref+ for ADC conversions I removed solder bridge SB12 (coupling Vref+ with VDD) to input my own reference voltage (~3V) at Pin 6 CN7.After removing the SB12 however the STM 32 device is not...
