Hello everyone,I've been working with ST link v2 programmer/debugger for a while with IAR embedded workbench. But recently each time I start a debug session or I appoint a break point and I arrive at the breakpoint, the IDE freazes for a while and wa...

Hello everyone,I'm working on a projects that countains a stm32l152re to communicate with temperature/Humidity sensor amongst other sensors and a DC relay to control some light bulps. However, when the relay is closed, it overheat and corrupt the me...

Hello,I'm using an stm32l151re to interface with mp34dt05-a mems microphone. I'm using it to determine noise level. The communication between smt32 mcu and the sensor is based on I2S protocol with dma. My issue is that my project consists of multiple...

First, I appreciate the time you took to answer my questions and to be more precise. I doubt there is a an electronic issue. I suppose it's a mechanical issue regarding the electronic board packaging which provides one output from the sensor position...

I appreciate the answer and to answer your question :What voltages/currents are you looking to switch?>> 230V/10A

Thanks for the reply. I appreciate the informations you presented. However, my question is there any firmware solution or a coding method that can reduce that ?

In the sonometer manual there is a parameter called Time weighting. I think it represents the integration time that you mentioned. The sonometer time weighting used is 125ms. Here is a link for the manual : https://manualzz.com/doc/4544581/downAs for...

Thanks for your reply.>might have to do with peak measurment and integration time interval?How can I check this ?
