When the USART is hot swapping，some datas will occur on TX RX pin；and the value of BRR register will be changed;the picture 1 shows the BRR before hot swapping;and the picture 2 shows the BRR after hot swapping. Why this question happens?And what...
Hi,According to datasheet, The main function of PA15 is JTDI, so I disabled JTAG and config that pin in AF_PP mode.Then if I don't initialize SPI1, I can control PA15 as GPIO. But if I initialize SPI1, this pin will hold high. Since SPI1 has occupied...
In trying to understand some motor control code in the ST Library I've come across some procedure names with STO_ as a prefix. Simple question what does the acronym STO mean?
Hello. So like title says I am having trouble making SDMMC work with DMA in 4 bit mode. I tried with FreeRTOS and without FreeRTOS didnt get anyresult. But it works perfectly without DMAIt gives either Rx Overrun error or timeout error. I tried it wi...
We are intending to design in this MCU. Does ST have a website that would indicate where this part is in its lifespan? I can only see that it is listed as "active".Thanks
Hi there.I have a board from some equipament which has a STM32F091CCT6 uC, and there are 3 leds, connected to pin GPIO_C13, GPIO_C14 and GPIO_A7. Anode from leds are connected to Vcc and Catode are connected in a resistor and then to the uC pins (so ...
Hello all i am trying to implement a simple thing that is trying to blink LED using a function. Below attached are main.c, project.c and project.h. If i try the same thing without using a function it works fine but if i use the function it doesnot bl...
The most important spec I'm looking for is INL error. I'v searched the datasheet, reference manual, and google search but to no avail. In particular, I'm looking for the STM32F072 series.
spi half duplex with dma,change tx ino rx,when finished tx process,start rx process,just set the "spe" bit of spi master(not set cstart bit),dma just starts working,and cntdr goes to zero,then rx process fail,spi report overun error.
Unfortunately I got a message that I may not attend to the workshop.I'm not interested in getting a Disco-Board for free - I can buy it by myself.Is it possible to particitpate the workshop as a "passive" member?I need no possibility to ask questions...
