Posted on September 10, 2017 at 16:20In the STM32L4x5/4x6 reference manual (and some other manuals too, like RM0090) the figure 374 shows that the RTC wakeup timer can be clocked with ck_apre, but the description of RTC_CR says that the alternate in...
Posted on September 10, 2017 at 08:32Hi,where are the sch or list of this EVAL board 'Free Pins' for GPIO usage,in sch file MB1246 , sheet: Extension Connectors the connectors are drown without listing which port-pin is free and which is used!regard...
Posted on September 07, 2017 at 14:43Hi,i am working on PWM output generation and input capture with the timers. What i see in the HAL description is that the OC and capture functions have always a '_IT' interrupt version counterpart.1. I am generat...
Posted on September 11, 2017 at 08:25HI.I'm trying to test with simple UART as the below code,I connect with RS232's TXD to GPIO_Pin_10 and RS232's RXD to GPIO_Pin_9.There is no problem RS232 kit, but I can't receive data correctly from kit.I always...
Posted on September 08, 2017 at 09:58Hello,I'm using STM32L100R8T6A.The problem I'm facing is that I do a Low Power Battery Powered Project, where it's necessary to detect that battery has been removed and I have backup capacitor for this case but w...
