Posted on November 13, 2014 at 16:32After replacing STM32F407VGT6 for equivalent VET6 I'm puzzled what parts of flash have been left out. This isn't described in the datasheets/manuals. Only the part number identification says 512k, but nowhere what...
Posted on November 12, 2014 at 19:08I'm planning to use the FSMC to memory-map registers of a FPGA. To save pins I would like to use multiplexing between data and address lines. Now, I need only a 8-bit data bus width but would like to address more ...
Posted on November 13, 2014 at 07:30 i want to transfer my src array to external memory, but i could transfer only first member of my array (0x01) to GPIO ports and hold, where is other 9 members? :( what can i do? #define SRAM_BANK...
Posted on November 13, 2014 at 19:03Hi all! I am interested instm32F37. They are notproduced inthe bodyQFN24thatI need. (Or my special design.) Can you producethis design, what is the minimum number.
Posted on November 13, 2014 at 10:19I'm using USB HS host mode with internal PHY but get a problem that i can't enter the interrupt when i plug or unplug my usb device. my program code is modified from host_device_libV2.10-USB_host_example. i just m...
Posted on November 13, 2014 at 17:19Hi I have started a quick developpement using mbed platform, in order to communicate with a MEMS sensor (sensor LPSH25 mount on STEVAL-MKI142V1), it works fine, I want to develop with MDK-ARM now (size of *.bin fi...
Posted on November 13, 2014 at 06:54To drive my application I use two DAC in a interrupt. The data sended to the DAC needs to count up and count down between two variable(bits) so that it creates a triangular wave. The maximum value is 4095. The fre...
Posted on August 17, 2012 at 04:58 The code below transmits 8 bytes from a sram buffer to SP1 using DMA. for(i=0;i<8;i++) SPI_MASTER_Buffer_Tx[i] = i+1; /* SPI_MASTER configuration ------------------------------------------------*/ SPI_InitStruc...
Posted on November 11, 2014 at 10:43it seems stm32cube in some parts is too heavy and have no speed optimization, Is this right? If drivers are too heavy and not speed optimized then make our 168MHz micro a 16MHz micro in practice and waste our reso...
Posted on November 12, 2014 at 12:04Hi! I am using a DevKit407 ( stm32f4 discovery + stm32f4dis-BB). I managed to set up a perfectly functioning CAN1 in Loopback mode. I assume I should see the test frame sent on Tx pin (PB9 on stm32f4discove...
