Posted on November 03, 2016 at 00:58I'm using a STM32F411 with an audiocodec driven by I2S stream. I'm runing out of RAM, so I'm trying to move OutputBuffer (the buffer that I use to create sound and used ond HAL_I2SEx_TransmitReceive_DMA). This buf...
Posted on November 04, 2016 at 16:59 When I start the ADC conversion the code jumps to ADC1_COMP_IRQHandler In ADC isr the EOC flag clears after first assembly instruction of isr code. So when I check for EOC flag if is set...the flag is already...
Posted on November 03, 2016 at 15:40Hi I had configured a the UART_DMA_ hyperterminal program for the evaluation board newly by cubemx and its working fine by USART_1. But whenI configured it for UART_8 for my mcu its sending the characters but I ca...
Posted on November 04, 2016 at 14:31Hello,We are planning to discharge a Li-Ion battery and measure the voltage of the battery with a STM32F103CB. This voltage should be used to terminate the discharge. We plan to calibrate the ADC of the STM32F103C...
Posted on November 04, 2016 at 14:32Hi guys. I was working with this board and it works well. But suddenly when i wanted to build and run my code (Attollic True Studio) into the board again it show an error that it failed to connect to ST-Link. Reas...
Posted on November 04, 2016 at 12:42I've compiled and linked the original sources without modifications of the board. After upload and starting the demo with the debugger the initialisation should start with LED3. here the code snipped: /* Initia...
Posted on November 03, 2016 at 16:08Hi I am triyng to use multiple MPU9250�s with Motion Driver 6.12 with STM32F4 Discovery. I am using TCA9548A 8 channel i2c multiplexer.In arduino solutionWire.beginTransmission(TCAADDR);Wire.write(1 << i);Wire.end...
Posted on November 04, 2016 at 11:00Hi,I am working on STM32F401 with VS1053b. VS1053b (slave) is SPI interface with SPI1 of STM32F401rct( Master). In order to communicate the vs1053b, we need to drive two different clocks of SPI SCLK (clock) i....
Posted on August 19, 2016 at 10:01Hi all,I need to interface with a common IC which needs to have the NSS low during the complete message of 32 clocks. I have all working, DMA is triggered by a timer and fills the SPI data register with the complete...
Posted on November 04, 2016 at 08:53Hi all,i want to build my own STM32 PCB with USB connection, I want to use the USB communication for sending Data via VCP(CDC) to the PC and to programm the STM32 via DFU. Currently I'm using the discovery board a...
