Posted on September 11, 2017 at 17:39Dear All,I need to use TIM1 to generate 4 PWM signals, hence I want to use CH1, CH2, CH3, CH4.I also need to use USB for firmware upgrade.Since on PA11 there are both TIM1 CH4 and USB-DM, I don't know how to rema...
Posted on September 11, 2017 at 14:09Hey,does someone use stdperiph_lib V1.5 in combination with stm32f071rb ?Just read in the changelog that it was updated in Dec. 2015: Add support of the STM32F070xB, STM32F070x6 and STM32F030xC devices.But did ...
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 04, 2017 at 09:49 Hello, I'm using a STM32F091VBTx microcontroller and for the application I'm implementing I need a variable to be constantly updated and it must be stored in a non-volatile memory in order to keep its value ev...
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...
Posted on September 11, 2017 at 09:50STM32L4, using internal bootloader, I can start it yet I need it not to open all available ports (usart, spi, usb) but limit it to only one dedicated uart port to avoid waking up chips linked to the other ports. ...
