Hello, I tried to start QSPI working on a Single flash mode but have a problem with non readable part config registers (NonVolatile, Volatile and Enhanced Volatile). As I understand when working in Dual Flash mode this registers should write and read...
e.g: Below are the execution time of memset() function at different locations.1. memset() plcaed at 0x0000000000219e96 : Time = 57.10 usec for 3k buffer size.2. memset() placed at 0x0000000000219d42 : Time = 28.66 usec for 3k buffer size.- memset is ...
Hello,I am using the ADC1 + DMA to sample 10 analog channels on the CM4 without any MPU config. When I remove any external trigger e.g. 3.3V power source on the analog channel, and I start sampling all 10 channels via the DMA , all values inside the...
Hi,I am trying to use the ADC with DMA but the values on the buffer are not being updated. Next i detail the steps that i have done:Disabled the ICache and DCache.Place the DMA buffer in a separate section in RAM_D2 with the address 0x30000000, so th...
The execution of an interrupt handler can be preempted by an exception having higher priority.How many interrupt by an exception having higher priority can be executed?In the link below, two interrupts are generated. Is this number infinite?
I can't get the SDMMC working with DMA on the STM32L4A6ZG, so I'm looking for alternatives. I've already started down the path with the NUCLEO-144, so I'd prefer something that I can get on that. I've heard (from Tesla DeLorean) that "the L4 has at l...
I am using stm32h745i-discovry board as my development in the arm keil. Here I need the uart communication . could you please send me the example code for this.
Hello,I know that it is possible for mcu which has several ram areas such as RAM_D1, RAM_D2 like STM32H7. STM32l1 has only one RAM. Because I can not divide RAM for some important data. But I saw an STM32L1 example created on KEIL and divided some ad...
