Posted on January 30, 2018 at 15:53hello friends i recently got an stm32l4 I just go past the led blink i am trying my hands on interrupts I am trying to configure a falling edge triggered interrupt on A0 and PC15 so far works fine for GPIOA but th...
Posted on January 31, 2018 at 09:21Hello, that's the SRAM of STM32H7x3 microcontroller. I need to receive over 800 kib of data on high speed and place it in RAM via DMA. I read that there's 864 kib of ram here but I was confused to find out that it'...
Posted on January 31, 2018 at 02:48Hello, I have a separate MCU acting as the SPI Master, sending data in multiples of 64 bytes (anywhere from 1x 64 byte group, to 10x 64 byte groups) - all during a single transaction. So NSS goes low, 64 bytes to 6...
