Posted on March 15, 2013 at 08:39Hi! The Discovery board based on f407 served me as a starting point in preparing a course on the use of microprocessors for local students, which do not have much experience with hardware, but are familiar with the p...
Posted on June 10, 2013 at 23:31I noticed something strange with the CAN_TransmitStatus function in the stm32f10x_can.c (V3.1.2) peripheral driver code. Most of the time it works fine but occasionally it returns the wrong status. The root cause is i...
Posted on February 05, 2014 at 13:42Hi,Kit using : STM32Discovery Board(STM32F100 controller)I have implemented the input capture mechanism for Timer15 channel 1. In which I set triggering for both falling and rising edge.Now I am trying to port the...
Posted on February 13, 2014 at 05:38I have a bit of code to output some debug using SWOvoid swo_init(){ uint32_t SWOSpeed = SWO_SPEED; uint32_t SWOPrescaler = (SystemCoreClock / SWOSpeed) - 1; // SWOSpeed in Hz CoreDebug->DEMCR = CoreDebug_DEMCR_TRC...
Posted on February 13, 2014 at 05:31I am using a STM32F405RG as a USB host. I've implemented the ST USB Host library (version 2.1.0) in a way that supports multiple devices behind a hub. In order to seemingly support unlimited devices (as much as po...
Posted on February 09, 2014 at 16:57Hi, I have a problem connecting to a STM32F051K6. I tried to use the Debugger on an STM32F0DISCOVERY-Board. It should be an ST-Link V2. Therefore I disconnected the Jumpers on CN2 and the Soldering bridges on SB19...
Posted on February 12, 2014 at 20:22My original post *poof* gone..I am attempting to use I2C2, however Oscilliscope does not see any activity on either SCL or SDA. Using STM32F0308-Discovery. Obviously timing parameter is wrong, have tried many as I...
Posted on February 11, 2014 at 22:28 Hi, I'd like to use the USART3 of the STM32F407 (Discovery Board) in Half Duplex to control a Dynamixel AX12A. My USART initialization is the following: void USART3_init(void) { GPIO_Init...
Posted on February 12, 2014 at 15:07I have been reading conflicting reports on writing/reading to/from FLASH when running your program code from FLASH as well.First of all, where is there documentation saying that you can stall the processor by doin...
Posted on February 04, 2014 at 05:54I am using a STM32F303 Discovery board and am not really sure where to start. I am attempting to use EWARM and ST-Link Utility together. Never having downloaded code to anything more complex than Arduino, etc., I ...
