Posted on January 24, 2018 at 05:25I am trying to read data from an I2C peripheral. This peripheral requires the I2C clock to be at 100kHz. When probing with a scope, the SCL line shows 400kHz. From the STM32CubeL4 I2C examples, the I2C_timing regis...
Posted on January 23, 2018 at 18:55I am using usart1 for asynchronous communication. Microcontroller is nucleo STM32F103RB.Here's is how I am receiving data if parity bit is not set,char USART1_Receive(){ if((USART1_SR & 0x00000020) == 0) // n...
Posted on January 23, 2018 at 13:24Hi STM community, Currently we are developing an application with STM32F779I eval board.I am using Cube Mx and System work bench for STM32. We are facing issue with RAM.My application uses FreeRTOS, FatFS and SD Ca...
Posted on January 22, 2018 at 21:58Hi, I've made a pcb using the stm32F446 mcu, 64 pin package, but I have a problem with it. I have four LED's attached to pa4 to pa7. Two of these work fine, but the ones on pa6 and pa7 only lights up entirely when ...
Posted on January 19, 2018 at 14:48Dear All,I would like to generate a 2 kHz �10 V Sine-wave with Hann window, as shown in the figure below. Do you have any ideal how to implement this function in STM32F4, and are there any additional circuits requi...
Posted on January 23, 2018 at 14:33Hello,I have been looking for a library for the ds18b20 compatible with stm32f0 and with the HAL driver but without success, so I decided to modify old one to make it compatible.this lib uses while loop delay, the ...
Posted on January 23, 2018 at 10:37I found a strange behavior of the STM32L NUCLEO cards. I installed a sensor network using Contiki and I implemented an RTC. If I try to set RTC_SYNCH_PREDIV to a value above 1023 (for example 2047, 4095, ... up to ...
Posted on January 23, 2018 at 14:43Should the NRST external reset (PINRST) be set on an STM32F407 after a power reset?I want to be able to count the number of each type of resets in my code. The problem that I have is that the NRST pin reset is alwa...
Posted on January 22, 2018 at 19:15Hello to all. I noticed that in the latest release of firmware for the STM32F7 (v1.9.0) the example application FatFs_USBDisk no longer works. During any fs_open command, an error is generated, and the app halts.Th...
Posted on January 23, 2018 at 13:24Hi,I am developping an application with a STM32F746ZG using the SPI interrupt to send data to a DAC. I am using the HAL_SPI_Transmit_IT() function to send this data in order to send a waveform. The fact is that I w...
