Which is better CEC peripheral clock selection for STM32H743, LSI or CSI, if no LSE availabe?
Like the topic says, is the CEC module expecting a clock of nominally 32.0 kHz from the LSI, or nominally a 4 MHz/122 = 32.8 kHz clock from the CSI? It seems that the tolerances for the LSI and CSI can be too large for reliable CEC communications, an...
Resolved! STM32l475RC - TIM3 configuration when running in low power mode
Hi,in my Project I need a millisecond timer. Therefore I try to use TIM3. Now I have the following problem.For example, when the MCU runs in Run-Mode at 80 MHz TIM3 fires every 1 ms according to its configuration. But when the MCU runs in low power m...
