STM32L152 LSERDY
Posted on August 28, 2013 at 08:58Hi, I have a batch of STM32's which use the LSE. On all of the device LSE starts normally(i.e. you can see it oscilate with a scope). However, on a few of the devices LSERDY never aserts to indicate that the clock...
STM32 Timers + Interruptions - Error
Posted on August 28, 2013 at 12:46 Hi, I set an interruption handler for a timer. Each time it calls the handler I change the state of a IO. But I'm getting problems for frequency above 80kHz. If I set the period to: TIM_TimeBas...
Need information about ADC's external impedance
Posted on August 28, 2013 at 11:17Hi everyones,In the datasheet for STM32F407xx, in the electrical characteristics part (12-bit ADC characteristics), they deal with the Rain value. they define it like that : used to determine the maximum external im...
