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 12, 2015 at 15:51I'm using STM32F051R8 board but i'm unable to configure UART in 7bit bata and one bit parity mode. Tried changing M and PCE bits of UART CR1 register but no luck.
Posted on September 01, 2015 at 12:39after download the Firmaware Package STM32F4 1.8.0 with STM32CubeMX Version 4.10.0, an error occurs: stm32cube_fw_f4_v180.zip (MD5 file checksum is not good). It tried it several times on different PC's with the ...
