Posted on May 03, 2018 at 14:00I'm working with stm32vldiscovery and I'm going to use max232 for USART. I'm using usart1 (pA9 and pA10 as TX and RX).The question is witch is the best way to make it wortk correctly and safetly specially with the RX p...
Posted on April 17, 2018 at 17:43which is best to power up ''' STM32VLDISCOVERY ''' via 5V pins and a ground or 3,3V ???also which is best to for Digital Input for STM32VLDISCOVERY, using 5v or 3,3V ???In the data sheet I found that bouth of th...
Posted on January 25, 2018 at 02:00Hi I'm new with stm32, I bought an stm32f0discovery but I can't work with it I wanna get help or some tutorial please.
Posted on May 03, 2018 at 23:38For some reasons I just could work with MAX232. Neither 3232 or 3223 ...I guess voltage divider works but I'm searching if there's a better way.
Posted on April 19, 2018 at 09:22Yeah actually I don't wanna work with it. I did read the datasheet. as you know the regulator could be so hot, that's why I'm not sure about making it work for a long time with 5V. I just wanna be sure.
Posted on April 18, 2018 at 11:57Thanks, mmm, what if I power up the stm with 5v and then use the stm's 3.3v out as inputs for the switches, or buttons or whatever ???
