Posted on August 08, 2015 at 05:21 Hi! Device is STM32F103C8 A update event from TIM4 is used to trigger DMA channel7 who then is supposed to transfer 9 values in circular mode to TIM3 CCR1. However the DMA transfers only one value and th...
Posted on August 01, 2015 at 15:43I have an idea about a CAN bus with 100-150 devices and a central processor. But we have very limited power available. All but one device should be awake at one time. There is no power to keep 100 CPUs active simult...
Posted on August 08, 2015 at 15:20 Hi, I've been working with SW 1.2 and integrated cube MX on my custom board. It has a stm32f411re with a TI audio codec. I could make a project on cubemx, on it I configure the occillator to HSE 12MHz crysta...
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...
