On an L412KB Nucleo, I configured TIM1 to use ETR2 as a clock source and set the counter period to 1 so that every time a rising edge occurs on the TIM1_ETR pin occurs, it should trigger a DMA. I set up DMA1/Ch6 to respond to TIM_UP for a byte sized ...
HII am using stm32l496 and want to use external flash memory MX25R6435F .Although this memory has 64 MB of memory, I set it to 8 MB in the ioc file and mx25r6435f library, but when I write in that string or character, it is not written correctly and ...
Since the PIN of STSPIN32F0 is not enough, it is implemented to view log messages using PA14 (SWD_CLK) as UART.But after that, I can't download it, so please inquire.1. Could you explain that re-download the MCU in this state?2. I don't have any PI...
Hi.It seems, that sometimes data in cached memory is corrupted.DMA transfer data from SPI to SRAM2 (0x30000000). I use ping-pong buffer in SRAM2 (two similar buffers). Data processing performing for first part of the buffer in thread, while second it...
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...
