Bidirectional Line Termination - will just one resistor work?

I am designing a PCB for an ST micro MCU with external SDRAM.On the demo board, ST is using one series resistor termination for the bidirectional data lines. ST places this resistor at about 30/70% split of line length, where the resistor is 30 % of ...

STM32L431 ADC initialization problem

Hi. I have a problem with ADC on a custom board with STM32L431CBY with external 24 MHz clock. Everything (UART, SPI, DAC e.t.c.) works fine except ADC. Clock initialization:static void setSystemClock(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_...

Compiler for STM3240G-Eval

Want to know the compiler for STM3240G-Eval Board.

HAL_I2C_Master_Receive_DMA not returning updated values.

Hi,I am using one I2C based peripherals with Interrupt enabled.While using "HAL_I2C_Master_Transmit" and "HAL_I2C_Master_Receive", it seems to work properly with ISR.But, when I am using the following I2C_DMA:HAL_I2C_Master_Receive_DMA(&hi2c4, MPU_DE...

What the max ADC sampling Rate when using STM32H747 M4 Core? Does it same as M7 ?

Hi Everyone,I found the document(AN5354) talk about 16bits ADC Max sampling Rate and I verify that on M7 Core. It's correct.My implement include Total 3 ADC 3 Channel(one channel per one ADC) run 1Mhz Sampling rate and using DMA with timer trigger Bu...

STM32F107 Quadrature encoder

Hello,Regarding this post I am able to read my encoder value correctly. // STM32 TIM3 Encoder Decoder (PC.06:A PC.07:B) VLDiscovery - sourcer32@gmail.com #include ''stm32F10x.h'' #include ''STM32vldiscovery.h'' /**********************...

How to program an STM32H73x to put it in low power, that it consumes as little as possible, and that it can wake up with a GPIO?

I am using an STM32H735G-DK board to do my tests. My goal is to toggle a LED on PC2 every time I wake up the MPU when I put PG5 to ground. Once the LED is toggled, I want the MPU to go to the lowest possible power consumption. Does anyone have an exa...

Hello, I have got question: why generally 16 bit microcontrollers are not popular like 8 or 32 bit?

Order of ADC calibration step

The errata sheet of the STM32L476VG states: I wonder if the order of the ADC calibration step is important. I was performing the following steps:1- Set ADC clock source2- Enable ADC clock3- Disable deep power mode (ADC1 and ADC3)4- Enable ADC voltage...

HI, I use cubeIDE. I was trying to use NVIC functions such as NVIC_SetPriority(EXTI1_IRQn,1), but the function and EXTI1_IRQn are not recognized, and it gives me an error. is there is a header file that I should add? Thanks very much.

I am trying to write the drivers for stm32f401 nucleus without using HAL and by writing to registers directly. when I created the project I choose the target project to be empty instead of STM32Cube To make sure I do not add HAL drivers. I know there...
