Posted on February 27, 2017 at 11:28Hello,Rm431/385 and 410 document the value 0xff7f0080 as default value for FLASH_OPTCR1. The high halfword does not make sense and instrction on a new device shows a value of 0x00400080 that does make sense.Pleas...
Posted on January 05, 2016 at 13:50When preparing to receive the data on OUT isochronous endpoint, the HAL sets up the even/odd flag once when you call the PrepareReceive for that specific frame that is active at that moment.However the data may com...
Posted on June 12, 2017 at 17:51HiI created new STM32F103C8 project. I'm using STD Periph library. STM32F103 works with 8Mhz HSE oscillator. But I did not get 72 Mhz. I'm measuirng PLLCLK frequency with MCO. RCC_MCOConfig(RCC_MCO_PLLCLK_Div2); I wa...
Posted on June 12, 2017 at 15:05I have on radio transmitter and one radio receiver like on the picture. What I am trying to do. I send data through USART2 PA2 (pin2) on data transmitter. I connected usb-uart to PA2 (pin2), and looked in terminal wha...
Posted on February 23, 2017 at 11:32Hello everyone,I work on a clock project and have a problem with the LSE crystal. I firstmade my program on a STM32F0Discovery and it worked properly. Then I made a PCB with a STM32F030R8T6 and tried to program it...

Posted on June 12, 2017 at 18:30The data sheet for the STM32L476xx (DocID025976 Rev 4 states on page 124, footnote 2 of table 40) states:� In order to save the full GPIOx current consumption, the GPIOx clock should be disabled in the RCC when all po...
Posted on June 12, 2017 at 17:12Hello,I tried my LCD with parallel FMC-16bit on the NucleoL496 kit. All is working so far so good.Now I working on my board and this is a L471 processor.The problem is that it crashes when I try to writing to FMC(0x60...
Posted on May 27, 2017 at 00:08Hello everyone, I started programming for one of my student projects but I am pretty hung up on the USART2 configuring. I have worked with Arduinos before, but I must admit that STM32 is a complete different level :) I...
