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 ...
Posted on September 14, 2015 at 13:36 Hello all, i started working with a small stm32f103c8t6 (medium size device) which i want to use it without any external crystal, so i configured it with usage of internal HSI oscilator. From wha...
Posted on September 14, 2015 at 12:25Hi, i'm just start working with the Discovery Board STM32F072B. I've installed CubeMX, the MDK-ARM 5.16a & ST-Link Utility 3.7.0 At first i want to go through the examples of the Disco-Board. I can start and rebu...
Posted on September 11, 2015 at 13:11Hello Everybody.I am having trouble with the output compare function of an STM32F401RE. I am testing the OC function to generate a waveform by toggling an output at the compare point and the overflow point.The co...
Posted on September 13, 2015 at 23:14Hello I am trying to figure out DMA and write buffer for incoming TCP data to send over USART I was thinking about using circular DMA (for USART TX) and add data to buffer. When new data arrives stop DMA and add...
Posted on November 19, 2012 at 13:29Hello, everyone!I have a question about ADC's EOC event, when is this bit been set?For example,there are 6 ADC channels in my program.Is it right as bellow:A channel converted--EOC--B channel converted--EOC...F ch...
