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...
Posted on November 06, 2014 at 20:08Hi we are using STM3220EVAL-G evaluation board. In our project we want to establish two UARTs communication with two different external devices in Interrupt modeUART related function are defined in STSW-STM32062 ...
Posted on September 26, 2014 at 16:43 Hello. I'm trying to run a simple I2C test with my STM32 board and I can't get it to work. I'm using STM32F0 Discovery kit (master) and one slave device (some module) that I want to communicate with via I2C b...
Posted on November 11, 2014 at 14:54 Hello, I am trying to interface a MEM on I2C of STM32F My code gets stuck when I read a register in the ''I2C_Reg_Write'' function below. It sticks at ''while(!I2C_CheckEvent(I2C1, I2C_EVENT_MASTER_...
Posted on November 11, 2014 at 02:02Hi. I have boards with stm32f429 and rs485 driver, all running on freertos. When 4 boards are connected by rs485 somtimes one board is not communicate, other 99% time all is working great. When I switch power off ...
