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 ...
Posted on February 05, 2013 at 20:46I cannot get stop mode current below 1.1 mA in the IAR STM32L152VB eval board. This is the code to prep and then go to stop mode:lowPowerConfigGPIO(); (this configures all GPIO pins as ADC inputs)PWR_FastWakeUpCm...
Posted on February 05, 2013 at 15:05I'm trying to understand how below function call from usb_bsp.c source file works:RCC_APB1PeriphResetCmd( RCC_APB1Periph_PWR, ENABLE );This is from Reference Manual:5.3.8 RCC APB1 peripheral reset register (RCC_A...
