Using a STM32H7 and internal ADC through DFSDM using sinc filter and aliasing protection
Using a STM32H7 and internal ADC through DFSDM using sinc3 filter and would like aliasing protection.The sinc filter has the notch at the new sample frequency. I would prefere to have the notch at half the new sampling frequency to get better aliasin...
PDM_Filter() erroneous 1st 2 PCM-converted data
Hello newbie here.I am trying to learn how to convert PDM data to PCM using PDM1_filter() function, I am using GCC.The first 2 converted PCM data seems to be abnormal as can be seen later.Firstly, instead of directly interfacing to a microphone or an...
Reading data ADC MCP3208 - STM32F103C8T6
Hola comunidad!Estoy desarollando una etapa de un proyecto en la cual deseo adquirir los valores digitales de un ADC MCP3208 mediante comunicación SPI utilizando un STM32F103C8T6.En primer lugar, comparto el código que realice:/* Adquisición de datos...
stm32 CAN bus: A sends data to B nodes.
I have 2 nodes, A and B, they set filters for both, now A is sending data frame, B can receive the data from A. but A originally can receive data from B, but after around 1-3 mins the receiving data mainly from itself, minorly from B. but if i rese...
I2C timeout not working correctly
I have tried enabling the timeout function in the I2C controller by setting a value in TIMEOUTA and setting TIMOUTEN. I can see the bus working normally on a scope, then when I connect with the debugger ( no reset, no upload ), the halt causes the t...
Why does the Crystal Clock on STM32F103 have an offset and why is the microcontroller very sensitive to this offset?
Hi,I am currently having trouble with a Hard fault issue that I cannot understand and I was hoping someone might have come across a similar issue. I have a Crystal Oscillator with a 16MHZ clock at the input. I use the MCO pin from the microcontroller...
Any resources on how to ensure mechanical robustness using WLCSP parts?
I've been looking for specifications and/or white papers on the best practices for ensuring the WLCSP is able to be mechanically robust. Are there any documents that detail how much of a bend or flex is allowed in this type of package?I'm specificall...
