Posted on July 28, 2016 at 18:23 Hi All, I was trying to measure duty cycle and frequency of a pwm signal by using a timer with pwm output to generate pwm signal and another timer in reset mode to measure pwm using one of the example. Th...
Posted on July 27, 2016 at 23:29I have code that drives the FSMC & in turn an SSD1305 LCD controller. Trouble is, in order to integrate it with the rest of my application, it needs to use the HAL, as all of my SPI, I2C etc is HAL-based. I've written...
Posted on July 28, 2016 at 15:12Hello,I am trying to capture the SPDIF input packets received on STM32F7. I am using a LPCM Stereo input from a DVD player. DMA stream 1 is configured to receive data samples from SPDIF stream. I am receiving a Synchr...
Posted on July 27, 2016 at 22:51I keep seeing references online to demo code for the ST chips. Where exactly is it? I have went through through all the Atollic folders, but found nothing. I have went through the CubeMX folders and also found nothing...

Posted on July 28, 2016 at 14:35When I compile the sample firmware for the NUCLEO-L476RG board using the provided project for the Keil IDE, I get the following error:STM32F4xx-MEMSMIC1\STM32L476-MEMSMIC1.axf: Error: L6218E: Undefined symbol APBPresc...
Posted on July 28, 2016 at 11:09Hello all, STM32F1xx ref. manual (RM0041) states different USART receiver tolerances to clock deviation depending on whether DIV_Fraction is zero or not (see attachment). Could someone please explain to me why fractio...
Posted on July 26, 2016 at 03:17We are currently using the USB audio with the STM32F4, which works well. However, the power consumption of 40mA is something that we want to improve. Would change to STM32L4 help the situation? Our use is just using...
Posted on July 19, 2016 at 09:36Hi my name is Etienne, I am new to microcontrollers and I'm still banging my head against the wall. I would like to run a simple USART printf function to get things going. To keep it short, Ive got a Nucleo F103...
