Posted on March 05, 2018 at 06:22Hello;I have started to work on I2C communication by examining adxl345 sensor. I wrote basic code to test if my code works or not. According to the ADXL345 technical documentation, the 0x00 register should return dev...
Posted on March 06, 2018 at 18:05I have a circuit which can measure an input voltage. It is connected with an 100K/10K divider with a 10nF added for HF suppression. The same connection point is also connected to an analog comparator which is attache...
Posted on March 07, 2017 at 17:02I've just assembled and tested (by pin toggling) my custom board.Initial clock configuration is ok (and I would not recommend using Eclipse plugin, standalone app is way more stable); LED blinker is ok; basic UART co...
Posted on November 03, 2017 at 19:25Hello,I just wanted to let you know that the stm32cube 4.23 v1.0 generated code for MX_SDIO_SD_Init on the stm32f407 is missing a call to BSP_SD_Init(). BSP_SD_Init is generated by the Cube but never called neithe...
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 ...
