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...
Posted on October 22, 2015 at 11:47Hello,I would like to program an external flash (S29GL128S10) connected to the STM32F429 at address 0x64000000 using the ST-LINK Utility. I didn't find an external Loader for this need so I am trying to create it ...
Posted on October 22, 2015 at 10:58Hello, STMStudio seems to have not received any update since last year and so does not support STLink-V2.1. Is support for STLink V2.1 planned or is STMStudio EOL?
Posted on October 20, 2015 at 10:18HiI use stm32f429-discovery board. I want to use uc20 (GPS/GPRS) module.uc20 has usb interface. I want to connect uc20 to stm32f429 with usb interface. I dont now how to develop driver.also uc20 has multi interfac...
Posted on October 22, 2015 at 07:08HelloI try the demo project to learn UART initialisation and usingSTM32Cube_FW_F4_V1.9.0\Projects\STM32F401RE-Nucleo\Examples\UART\UART_Printf\EWARMoutgoing Communication is fine. Demo is working.RxD and TxD are co...
Posted on October 21, 2015 at 17:36Hello, I'm working on a project on a STM32F429 and we experienced every 10 or more days a board reset. Based on the fault handler I detect that somebody is wasting my memory but I cannot get who is wasting it. I le...
