Posted on November 28, 2012 at 22:36I'm trying to upload a ChibiOS demo to the STM32F3 Discovery board. The project builds fine under IAR and appears to connect & program correctly over the onboard ST-LINK. However, when I change the code (i.e. comm...
Posted on November 28, 2012 at 14:34hello everyone, i`m working on an academic project.i`m trying to read sensor values and needs to send the readings after calculation to PC via USB or Serial port Does initializing and sending data to USART1 requir...
Posted on November 29, 2012 at 09:38Hello everybody,I have a problem. I'm using STM32f103rbt6. I'm using SysTick and USART interrupts. They are working independently. SysTick is used for Delay operation. But in a case, I must use this Delay function...
Posted on November 23, 2012 at 23:08Hi,Does exist any serial library for STM32 ? I searched on this forum and google and I found nothing, I'm looking for a traditional serial lib that allows to send other types of data than char (int32_t, float ...)...
Posted on July 18, 2012 at 15:21I am currently working on a project in which i have to interface SD card with STM32f100RB.I did the same with 8bit PIC microcontroller using Application Library provided by Microchip.for STM32 i get a FATFs module na...
Posted on November 28, 2012 at 15:09Can DMA1 control SDIO and be responsible for transfer data from memory to SD card? I'm using DMA2 for different data transfers. Based on Table 23, page 173, document ID 15403 rev 4 it is not possible because SDIO ...
Posted on November 28, 2012 at 19:38hello Does any one know how to send sound data to headphone DAC on CS43L22 ? main goal is to read data from mic, that use convolution with my low pass filter coefficients, and then send data to headphones. Somehow...
Posted on November 26, 2012 at 15:32Hello all,I'am porting an stm32f103 application to an stm32f051 It is a bootloader which loads an application via RS485However I ran into problems with clearing the usart buffer. The uart interrupt is enabled for...
