I use AS4C8M32SA-6BIN on my board (https://www.alliancememory.com/wp-content/uploads/pdf/dram/Alliance%20Memory_256M%20SDRAM_AS4C8M32SA-6_7BIN(BCN)%20A%20die_rev%201.0%20November%202016.pdf)But I get HardFault when I try to write to the address 0xD00...
Hi STM Community,I want to write media files [Images- .png ,.jpg,.bmp), (Video files-.avi,.mp4,.emf) ,(Audio files- .wav,.mp3,.bin)] to External QSPI Memory. I found that, we can write media files to external memory from USB Key and SD Card. But, I d...
I'm trying to set up TIM2 timer on my NUCLEO-H743ZI2 board (STM32H743ZI MCU) to start TIM2 timer on a rising edge of a GPIO input pin. I'm using STM32CubeIDE with STM32CubeMx plugin. Is it possible to set up the hardware to start the timer automati...
Hi,I would like to use the SAI as full duplex slave mode with I2S/PCM protocol.I'm not sure about the configuration and which pins are TX and RX when using Cube. In the parameter I can set the audio to transmit or receive.In this case SAI_SD_A will b...
Am new to the STM32F boards. Have been using an STM32F103C8T6 with success using Arduino. Was attempting to get the F411CEU6 connected and "did a lot of things" to include things with the ST-Link. Now when I connect the 411 via USB the blue LED no lo...
I have an ST link V2 and a custom board running at 3.3V generated by an on-board regulator powered from a battery. Google is sending me mixed messages about connecting VAPP (pins 1 and 2) on the ST link to VDD on the board. I'm a bit worried about de...
Hi, allI am trying to receive packet from uart3 and send them to uart2but the results of my trials are:transmit occurs every main cpu clocktransmit occur just oncewhich I thought was:receive packet from uart3 when packet arrived, independentlytransmi...
I am attempting to read a NEMA message from a GPS over UART.Im expecting the message to be about 75 chars/bytes long.Heres a sample of the data I'm seeing when using an ardunio for testing the GPS data out over UART.$GNGGA,011112.00,3214.62073,N,0580...
I've got some code working from an example for USART RX DMA Circular. I'm to the point where I can receive the UART data but I need to now use a write to a protected (by a binary semaphore) circular buffer from the interrupt context HAL_UARTEx_RxEve...
Hi,I've seen that in many stm32 tutorials (such as blinking LED and uart tutorials) they make use of a "while (1) " loop located in main.c: But, in the main.c generated by cubeMX for my stm32l496ag board i have only the following single while loop, ...
