Posted on August 14, 2016 at 19:19Hi,I would like to utilize either a 128Mb or 256Mb, and someday, maybe even a 4Gb external SDRAM chip. If they can just be swapped out on the board all the better.The F7-DISCO makes a point that due to design consi...
Posted on August 12, 2016 at 01:09 A few details: both code and data caches are enabled. 216MHz SysClk. Timer ISR schedules a task every millisecond. SCB.SHCSR=1<<18 to enable use of usage fault ISR for the fp trap handler. All ISR’s mentioned a...
Posted on August 13, 2016 at 19:25 Hi all! I'm trying to create a parallel synchronous data transmission using DMA and GPIO on a STM32F051 MCU. I've been following the AN4666 document that ST released, but is set up for STM32F4 MCUs. I also don'...
Posted on August 08, 2016 at 08:42Hi all,I've built USART2 connection with using none-flow-control via rs485 through my pc. Sending data from my pc to stm32f103 is working correctly however, i can't send any data from stm32 to my pc.Do you have any ...
Posted on July 29, 2016 at 18:58Hi,Has anyone worked with STM32-MAT release 4.3 on the ADC examples? Could anyone tell me how one can run this example and get the ADC reading via USART3 block back to simulink host PC?I am not sure if this example is...
Posted on August 12, 2016 at 14:26Hi I want to know if I can reach a writting speed of 3-4Mbytes/sec to MicroSD ?Microcontroller is STM32F103RET.Clock rate: 72MHz.MicroSD 2-4G calss 10.SDIO protocol.If you have any same experience , please to help m...
Posted on August 12, 2016 at 09:36 I'm working with an STM32F401RC which should have 256kB flash, and 64kB RAM. However I seem to be running into memory issues well below that limit. In my code I'm declaring 9 total float arrays of size 2x700...
Posted on August 12, 2016 at 10:48Hi, I was trying to configure HRTIM of STM32F334C8T of my STM32F3348DISCOVERY board with STM32Cube and encountered an issue. I set External Event 6 as: - Source : External Pin (source 1) - Polarity : high - Sensitiv...
Posted on August 12, 2016 at 12:12Hi, I want to transmit and receive data between two STM32F401RE NUCLEO boards. Performance does not matter, so the simplest approach seems to be using the blocking HAL_SPI_TransmitReceive(..) function on both sides....
Posted on August 10, 2016 at 23:11Using CubeMX version 4.16.0 with DMA it does not let you turn off FIFO mode. The check mark does not deselect. The generated source code needs to be manually modified to turn off FIFO. After the following change the...
