Posted on October 19, 2015 at 06:16 Accessing file in a uSD card should be pretty easy. STM32Cubemx can generate the code for you, however, I never succeed in accessing uSD with the code generated by cubemx. In my own board I have a ST...
Posted on October 19, 2015 at 07:04Hi,We would like to use the STM32L4 Discovery board with an external clock other than 8 MHz. SysClock = HSE. We plan to do this by disconnecting MCO from the ST-Link STM32F PA8 pin. Will we be able to continue t...
Posted on October 22, 2015 at 17:56Hi everyone. I am working stm32f407vgt6 with LCD 16x2. I don't know write code how to it run. Can You hepl me? You can send me a project stm32f407vgt6 with LCD 16x2 by me email: huynguyen300495@gmail.com . Help me ...
Posted on October 22, 2015 at 15:17Hello !!! I would recover my internal clock signal (configure to 16MHz) with an oscilloscope when I switch a pin of my microcontroller the signal is only of 450khz. Could someone explain to me why I don't exceed...
Posted on October 23, 2015 at 02:42 I have a SPI ADC conected to a STM32F4 I'm trying to use it with SPI DMA and DataReady signal with interrupt. This code works fine: while(1) { //PB0 = DRDY from ADC if ( (HAL_GPIO_ReadPin(GPIOB,...
Posted on October 17, 2015 at 11:07 I am currently trying to make DMA periodically pull data from memory (array ''buffer'') and push it to spi. When I manually call the SPI_Transmit function, it transmits something, the clock line shows up on my...
Posted on October 22, 2015 at 21:55 Hi everyone. I must ask for help one more time. I've been tring do it on my own (using examples and my own functions), but nothing works. I'm want to read data from ACC, just one register, on my F3 disco...
Posted on October 20, 2015 at 12:07Hello there,Looking at the example ADC_RegularConversion_DMA I am trying to obtain this functionality:Using DMA conversion is started in circle (never stoping) each time the conversion is finished it should put the...
