Posted on March 16, 2015 at 15:53Hi, I need to modify a PWM inside an interrupt, I though that It would be easy, just changing CCR2 to the new desired value but it is not working properly.The change is not happening each pulse, it is a bit random.. ...
Posted on March 16, 2015 at 16:25 Working with the STM32F439 UART and originally used DMA for TX and RX, and that was working. For other reasons I wanted to change RX to use interrupt, and I had difficulty getting it to work... I got things work...
Posted on March 16, 2015 at 12:36Dear users, I recently got a present - STM324x9I-EVAL board. So far I've been tinkering with Arduino's and made some mini projects. But this one surprised me - I saw almost no references and ''how-to'' online (in com...
Posted on March 16, 2015 at 08:52 I am trying to implement this project using the demo files provided by ST ''STM32Cube_FW_F0_V1.0.0\Middlewares\Third_Party\FatFs''. I have also written the necessory code for low level SPI driver. The command...
Posted on March 16, 2015 at 03:39Hi,I'm using my STM32F4DISCOVERY board with the STM32F4-BB shield which contain an Ethernet PHY/connector.i found many example for Ethernet communication using lwip and they work fine.i want to use my STM32F4 board a...
Posted on July 17, 2013 at 11:42Hey I'm running the STM32L1 chip with an XBEE unit and everything works perfectly except my Tx adds bits when there is an even number in the unsigned char (I typedef this as BYTE) being sent. Shows in Putty and X-CTU....
Posted on February 27, 2015 at 03:04Hi there,I have the STM32F3 discovery board and running a FreeRTOS.I also have the USB virtual Com port (VCP) code from here: http://www.pezzino.ch/stm32f3-discovery-usb-virtual-com-port/ I have tested the USB VCP...
Posted on March 13, 2015 at 01:51Hi, we're using stm32f103c8t6 to generate various PWM signals to various components on the PCB. TIM1,3,4 are used to generate different PWMs and TIM2 is used as a 1ms timer. Recently we've realized that we will need ...
Posted on March 15, 2015 at 04:33hi guy. I have a problem with accelerometter- gyroscope: how to set address for accelerometter by I2C I need code communication with gyroscope A3G4250D thanhk you very much!
Posted on March 14, 2015 at 11:40Hi, I'm measuring the pulse width on one line, using TIM2. Everthing is fine if I use Ch2 (on PD4 or PB3) but I can't get a reading using Ch3 (on PD7). I'm using : TIM_GetCapture1(TIM2) Here is the init code, thanks ...
