Posted on August 16, 2017 at 12:31 Hello. I'm developing an application based on Discovery board with stm32f429I. And now I have quite a weird issue:a high signal level is shown on unconnected input pins. Here is a code: //Configure PC4 ...
Posted on August 14, 2017 at 17:23Hey there!I'm working on stm32f051 MCU for a little project and a I have to receive and process data from its USART port 1.My issu is that I don't have any interuption from the DMA, and if I check directly on the b...
Posted on August 15, 2017 at 18:00According to AN3154 Datasheet I must write sector code in data field.But I dont know what is sector code and How can i find it for stm32f4 discovery?Just I want to erase sector by sector what I must do?(I know I mus...
Posted on August 15, 2017 at 22:04Where can I get the input impedance of the GPIO pins of the , The manual /Data sheet only provides the input impedance for the ADC.
Posted on August 16, 2017 at 01:53I'm not understanding proper use of TIMx_CCMR1->IC1F. Is it only for frequency? I'm looking for a way to filter pulses out whose width is too short of duration.
Posted on August 09, 2017 at 03:49Dear SIR,Issue : nRTS / nCTS behavior is NOT expectation,description:while(1){} empty loop is running on MCU, data is not taken from USART->RDR.The expectation is nRTS is set to high until the data is read from USAR...

Posted on August 15, 2017 at 19:55Hello.I am using a stm32F042 for some CAN communications, alongside a SN65HVD230 as transceiver.I have two boards (my own) using both those ICs.I made a simple program, based on the STM32 example, from a STMCube ini...
