STM32H7 I2C DMA ll, just sending once

Hey guys, I am trying to get I2C working with DMA or without, but I am having similar issues with both. The I2C sends out the data correctly the first time via DMA and the DMA_TC interrupt is called, however it gets never called again. I can also see...

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...
