Posted on September 14, 2015 at 20:00 Hi, I'm using a servo with a pwm connection and this is a part of code: RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOB, ENABLE); GPIO_PinAFConfig(GPIOB, GPIO_PinSource4, GPIO_AF_1); GPIO_InitTypeDef GPI...
Posted on September 14, 2015 at 16:40Hello Everybody.I am observing some strange behavior on the scope for a PWM output. I am driving it at 800kHz with alternating high time of 400ns and 800ns.In the TIM1_UP_TIM10_IRQHandler I am alternating the hig...
Posted on September 07, 2015 at 11:10 Dear all I use a master uP (STM32F072R8) and a slave uP (STM32F030K6) The slave processor is in AC main voltage and the main processor is galavanic isolated from main voltage. The main processor can rese...
Posted on September 13, 2015 at 16:52 Hello World! I need an EEPROM memory on my device and there is no I2C pin free to use AT24Cxx. So, i should use EEPROM Emulation (as said in AN2594 http://www.st.com/web/en/catalog/tools/PF257846#). I...
