STM32 MCUs Products

Is there any detail on leakage current of MCU input? I mean the characteristics of I leakage= f (V input). There is only "max 200nA @Vin=[0..VDD]" given. (STMH750, ADC capable inputs, but general info on any MCU input leakage also welcome)

STM32 Major LPTIMER documentation shortcoming or is it a silicon design error???

In looking at various LPTIM training documentation it's indicated very clearly that the LPTIMERs have a CNT reset as a function of setting bit 4 of the CR register. As this is an important capability, there seems to be a number of reference document...

STM32G4 ADC jitter from timer to conversion start.

Hi,What is the jitter value in nS when the ADC is configured for Asynchronous clock mode? consider CPU clock = 170MHZ, adc_hclk = 170MHZ, adc_ker_ck = 170/6 MHZ = 56.67MHZ and ADC clock = 56.67MHZ (PRESC = 0)ST inform in the manual that the jitter i...

Is the DMA busy until the whole FIFO is transferred in M2M DMAs?

I'm using triple interleaved ADCs to fill a buffer (6000*16bits) in circular mode via DMA,and I needed to know when I wanted to read the whole buffer via another DMA request and write it to a second buffer to be processed offline later would I need t...

Setup ADC + DMA STM32H745 Nucelo Board using CubeMX

I'm trying to port some code from a Discovery F7 Board to the dual-core H745 Nucleo board and I'm going to make use of the following peripherals:ADC, DMA, SDMMC, Ethernet and UART. I have this all working on the Discovery board but I'm having trouble...

I can't read chip ID with I2C

Hi, I am using bno055 with stm32f4 discovery board. I am trying to read chip ıd. HAL_IsDeviceReady function return HAL_OK but I can't read chip ID. Why is that? I tried to write my code or using library. Here is the code and stmstudio's return. (In c...

Why is setting up SPI to re-transmit by DMA taking too long, 1uS??

First, I would like to know if this code is correct to setup SPI to re-transmit by DMA again. GPIOA->BSRR = (1<<5); // start   DMA1->IFCR = 0x0FFFFFFF; // reset status   DMA1_Channel3->CCR &= ~( DMA_CCR_EN );   LL_DMA_SetDataLength(DMA1, LL_DMA...
