Posted on February 04, 2015 at 17:46Hello I'm using the Update Event (UEV) of TIM1 to count the CNT overflows (CNT > ARR). I'm using the capture compare IRQ of TIM1 on channel 1 to catch the rising edges of an input signal. Now I've got a strange t...
Posted on December 22, 2014 at 20:21I've really tried to google but did not really find anything.Are there any open source dev boards or just simple boards designed in KiCad and using the smaller or the larger LQFP packages?I have one for LQFP 100 b...
Posted on January 02, 2015 at 18:32Hello, I've test the STM32F303 for using it in a new project. The configuration and libbrary are used from the CubeMX with the IAR compiler. Now I can maximum transmit 4 bytes over the UART with one DMA transfer. H...
Posted on February 06, 2015 at 06:12I am using the st32cube HID middle ware library to implement a keyboard device. I am using USBD_HID_SendReport to send key data to the host. But this function will exit without doing anything if the bus is not a...
Posted on February 05, 2015 at 21:30 Hello, I found some unexpected behaviour with the 32-bit TIM2 module on STM32F4xx devices, and many others. When accessing the TIM2->ARR (a 32-bit timer) register, 16-bit writes have the following behaviou...
Posted on January 28, 2015 at 05:29 I created a project by STM32cubeMX, the project has : I2C interrupt communication with sensor, display data by LCD segment: int main(void) { MX_GPIO_Init(); MX_I2C1_Init(); MX_LCD_Init(); ..... ... .. B...
Posted on December 10, 2014 at 23:38Hi, I am trying a simpleexperiment using my STM L1 Discovery board. I have created a project using the STMCubeMX GUI that has the SPI port enabled as Master. The clocks have been configured correctly and I have a ...
Posted on January 31, 2012 at 14:53Hi, this example code does not work (I tried on the Keil board, PA10 is there available, so not any conflicts) The PWM frequency comes up with 17.5 kHz, as written in the example code. But the functionality, that t...
