Hi,I am trying to interface a signal with one of the ADC pins of the STM32F103 MCU. When the signal was scoped using an oscilloscope, it was seen that a noise component was added to the original signal from the MCU side. I have attached images of the...

Hi,I have a SPC570S MCU running FreeRTOS and is connected to a CAN bus. I came across an issue where the MCU freezes randomly, when there traffic in the CAN bus before is it switched on. Could someone help me in this matter. This happens randomly, an...

Hi TDK,Thanks for the reply. I already tried with an opamp stage(LM2904). But the result was the same. I will try with another opamp. Nisal

Hi Erwan,I will try this. Is it okay to use the FreeRTOS function uxTaskGetStackHighWaterMark() to check the size.I have 4 tasks running.Nisal

HI Luigi,I am extremely sorry, I missed that part. It is working fine now. Thank you for your help.I have another question regarding using unions in SPC5. Does the SPC5 micro controllers follow big endian format orlittle endian format? Nisal
