Posted on February 25, 2013 at 23:52Hello, Can someone inform me whether I can use (or do I need) USB CDC Driver on Windows CE. I am planning to connect STM32F4 Discovery to Cuwin Touch Screen panel which is operated on Windows CE. I checked the 're...
Posted on May 14, 2012 at 17:40hi, i am working on the stm32discovery i am trying to increment a timer (timer2 channel 1) each time the signal on the pin PA.05 is rising but the timer is random incrementing and not at each rising edge of the signa...
Posted on February 22, 2013 at 11:48Hi everybody, hi clive1! in an older PIC design, I use to store calibration data in flash. Then, an update can be done with values received via serial. With PIC, the pages to work with are smaller. With STM32F4xx ...
Posted on October 31, 2012 at 21:57I am communicating with a slave device and after the generation of the start condition, I am not seeing SCL and SDA pulsing. Below is the code: void DS2482_Init(void){ GPIO_InitTypeDef GPIO_InitStructure;...
Posted on February 24, 2013 at 20:15Hello. Sorry if my question seems stupid. I'm new to all this stuff. So i'm wondering can I plug usb stick to stm32f3discovery and upload information to it? I saw some discussions conserning usb host capabilities ...
Posted on November 19, 2012 at 20:01 developed my own ST32F405 Stamp and tried now to connect via SWD and STLINK/V2 to my stamp. What I get was a internal command error response from the STLINK/V2. The device is running with 3.3V Can somebody hel...
Posted on February 21, 2013 at 16:52Hi to everyone,I have a brushless motor 850Kv and one ESC's . The main aim of my task is to control my motor (forward and backward) by setting in different speeds. The microcontroller which i have is the STM32F4 ...
Posted on February 24, 2013 at 02:04I am using the stm32f0 discovery board and having trouble getting SPI to talk properly with an external SPI sensor. As a test case, I wrote a small program to send bytes from SPI1 to SPI2 and then compare these se...
Posted on February 21, 2013 at 22:48Hi, I am having a hard time to make USART RX work in DMA mode. I am using SMT32F103, just want USART2 to communicate with serial monitoring software like hyperterminal... I have had USART2 TX working in core drivn...
Posted on February 14, 2013 at 14:30Hello.As described on STM32F100 manual:The OCxREF signal for a given channel can be driven Low by applying a High level to the ETRF input (OCxCE enable bit of the corresponding TIMx_CCMRx register set to ‘1’)....
