Posted on April 18, 2013 at 09:21Hi, I am using an STM32L151VB part in a custom board. Is there any way to detect if an interrupt has been caused by a rising or a falling edge. I looked around in the reference manual and didnt find anything. I need ...

Hi,
I am using the STM32L151VB on a custom board. The MCU is clocked by HSI.
I have two rising edge interrupts on port E pin 9 and port E pin I capture the timer counter for timer 4 in both the interr...

Hi, I want to use the RTC's alarm A for waking up from standby. However, I cannot get the alarm interrupt. I am initialising timer 3 for interrupting every 5 seconds and reading the rtc within the interrupt hand...
Posted on March 22, 2013 at 11:27Hi, I am using the STM32L151VB in a custom board. The problem I have is with the watchdog timer. The maximum time out is too less for me to do anything that I intend to. Right now I am using the TIM4 timer for a long...
Posted on April 18, 2013 at 09:25Where are you buffering your received data? If you are receiving in an interrupt handler, then check the size of the receive buffer( usually an array ) and check if it is larger than 1KB to avoid ring buffering of yo...
Posted on April 01, 2013 at 14:09clive1 thanks for the suggestions. However the controller is right now in the run mode and not in standby. So I believe using the LSI shouldnt really be the issue here. Also sorry I forgot to mention the part number....
Posted on April 01, 2013 at 12:53I am using a timer to timeout if the modem becomes unresponsive. But how do I reload the watchdog in order to avoid a reset of the system. Isnt it unsafe to do so inside systick or some other interrupt?
Posted on March 23, 2013 at 03:59Yes its much lesser than what I need. I need something like 2 minutes, since I am performing an FTP upload using a GSM modem on the USART
