Posted on February 04, 2013 at 04:05It appears the TIM4 OC interrupts on CH2 results in occasionally missing an Update (overflow) interrupt. The situation is a 1 PPS GPS pulse triggers the TIM4 CH1 input capture. The 16 bit counter time is extend...
Posted on February 08, 2013 at 10:08Hi all, I'm still new in the ST environment, I'm trying to get a generic wireless m-bus example going with the STM32l152VBT6 board. For the moment it is still unsuccessful . When I debug my main program, I can see...
Posted on February 08, 2013 at 00:09Hello everyone. A week ago, I fought with a STM32F103, trying to get it fill some random buffer with its DMA1_Channel1 controller from its USART1 Rx ''events''. But neither the recipient memory would get filled, ...

Posted on February 07, 2013 at 05:12I am trying to send data to a PC COM port but cannot figure it outI configured GPIO, NVIC, and USART per specification and it all checks out. The strange thing is, when I connect the Tx pin and ground to oscillosc...
Posted on February 07, 2013 at 13:22Hi ,I have two development board which is the first have stm32f103vg LQFP100and second have stm32f103zc LQFP144 I can program LQFP100 model microcontroller using default SWD settings , but at the LQFP144 model i ...
Posted on February 06, 2013 at 02:21Hello guys,when I initialize for example this Interrupt:NVIC_InitStructure.NVIC_IRQChannel = OTG_FS_IRQn; I suppose it will have OTG_FS_IRQHandler as it's handler, but where can i look this up? I already searched...
Posted on February 06, 2013 at 18:37Hi, i am using the VCP for communication between a PC software an my STM32F207 device. Works ok so far. But if the device restarts while the PC software maintains the connection (or if somebody pulls out the cable...
Posted on February 05, 2013 at 09:46Hello, I have 16b parallel bus, 8MHz adc, and I need to read as fast as I can data to memory array which is 128 point long. So far I overclocked stm32f4 to 250MHz so I could do it faster. Original code is :while(i...
Posted on February 06, 2013 at 11:09 Hello, I am currently migrating from Microchip MIP to ST ARM Cortex M3 so I am new to Cortex M3.I have been trying for days to configure Advance TIM1 in STM32F103RB to output 6 Channel PWM but it has prove to be ...
