Posted on August 07, 2015 at 18:13Hello, I'm using I2S interface of my 411RE uC. I nee to send some int32 (positive and negative number) becouse my codec expect int32 format. But HAL_I2SEx_TransmitReceive_DMA expect unsigned number. So how do I do t...
Posted on August 08, 2015 at 04:53 Hello, I want to use USART2 of STM32 as debug output of application, so i overload printf as below: #pragma import(__use_no_semihosting) struct __FILE { int handle; } __stdout; void _sys_e...
Posted on August 04, 2015 at 08:36I used STM32F10x_AN2812_FW_V2.0.0 to have speex encoding /decoding on voice on my Discovery board. I used encoding functions and then decoding one and saved the data in .wav format using FATFS. It works very well an...

Posted on August 08, 2015 at 06:17 I'm working with the Nucleo F446RE, and the project that I created using the STM32 Workbench as well as all the standard library files include the stm32f4xx.h file rather than the stm32f446xx.h I noticed...
Posted on August 02, 2015 at 02:04 Guys, Does anyone of you have an experience on SPI1 for STM32F103VCT6 ? I read one code and trying to understand, why one pin has 2 function ?? Please have a look : /* Configure SPI1 pins: NSS...
Posted on August 07, 2015 at 08:09Hi, I am using two Multi channel ADC's (Controller used is STM103RCT6). ADC_1(Multi channel as IN4, IN5, IN6) with DMA1 channel-1 and ADC_3 (Multi channel as IN1, IN2, IN3) with DMA2 channel-5, for capturing the AD...
Posted on August 05, 2015 at 19:03I have build and tested the STM32cube Demonstration project using MDK-ARM for the STM32F4 Discovery and it worked fine. So I tried my own very simple project using STM32Cube interface to create the source for a US...
Posted on August 07, 2015 at 15:21We are trying to design a circuit which may need to work at -55 degree. And our current design is with stm32, which is very powerful.Here comes my questions:1. Does stm32f4 series have -55 degree (temperature) versi...
Posted on August 07, 2015 at 16:40Hello again!I'm trying to read from sd card using SDIO. I've succesed to tun it on STM32f103 @72Mhz and after a while I managed to read at about 10Mb/s. But when I ported this files to STM32f407 it hangs somewhere i...
