Posted on November 24, 2016 at 15:43Hi,I found an issue in the smt32cubeMX (ver 4.17.0 stm32F1 lib ver 1.4.0) when generating the I2C init code.I have an EEPROM connected to a smt32F107VC micro through I2C.Stm32cube does generate the following code...
Posted on March 04, 2018 at 22:21Good afternoon ladies and gentlemen.I've been trying to put analog read to work and been partially successful.First of all I tried using CubeMX for generating most of the init code and in 'manual pull mode' everythin...
Posted on March 04, 2018 at 15:35If I am not mistaken some variables on the USB code use hungarian notation e.g. bRequest, wValue, wIndex etc.However there is one prefix that I don't know what it means bmRequest.Is it something like multiple bits be...
Posted on February 27, 2018 at 09:17Hello Everyone;To send ASCII characters via USART I normally use Hal libraries and the function below;HAL_UART_Transmit(&huart2, (uint_t*)'Hello', 6,10);But, that one is for characters only.How can I send the valu...
Posted on March 02, 2018 at 18:48Hi,i have a STM32L475 with USB OTG as Host with USB Disk attached and an GPIOInt with callback void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin).If i build my HAL without USB all is ok, but when i build it with USB Supp...
Posted on December 20, 2016 at 15:00I am porting older code to the HAL library using cubemx for an STM32F4_Discovery board.My application consists of a 'bootloader' that resides in the lower segment of flash.The actual application resides in higher ...
Posted on August 01, 2017 at 09:46Hi there,I am trying to use DFU in my application, I have seen the sample codes available in STM32cube package but it requires user button to be pressed in order to enter into DFU mode.I want my application should g...
Posted on February 27, 2018 at 23:57I'm trying to put the Nucleo-152re dev board into stop-mode, when there are no tasks running. It successfully enters the stop mode(i think) but the current consumption is 150uA. I have read in the manual that it s...
Posted on February 27, 2018 at 23:00Hello, I am building an application in olimex e407. It's running FreeRTOS, lwIP, I'm running the ADC @10kHz triggered by timer and getting the data via DMA and I also want to communicate with an external uC via UA...
Posted on February 28, 2018 at 00:23The example code for bootloaders and applications both call HAL_Init and SystemClock_Config. I'm guessing that clock initialization is done in both apps because the RCC gets reset in SystemInit.I have tried reusin...
