Posted on June 27, 2018 at 07:33Hi,For an application we need a bulk of digital inputs(comes from sensors- about 30 inputs) and a bulk of digital outputs(go to relays- about 15 outputs). which solution would be better?1- using a high count digital i...
Posted on June 27, 2018 at 12:01I would like to power my STM32F446RE with an external source instead of using USB. Can I simply switch the position of JP5 such that it is connecting the E5V pin and the middle pin, and then provide the supply to the ...
Posted on June 27, 2018 at 09:32I couldn't understand why external back up pin VBat is kept ? Is it necessary to add a ext. backup battery#stm32f407 #stm32f4xx #rtc-backup
Posted on June 22, 2018 at 01:12I'd like to share an idea, actually a working solution for a common issue:''Why I cannot use a longer SPI cable?''''How can I make a SPI cable connection longer and keep still a high SPI speed/clock?''Issue:Potentiall...
Posted on June 26, 2018 at 20:23Hello, I have a PCB with LCD, SD-Ram, QSPI, CAN bus, SD card and everything works fine. I use a STM32F769Bi (208pins LQFP). Now I think the temp of the STM32F7 is very high (80-85deg). Normally I work with Stm32f103 a...
Posted on June 26, 2018 at 21:18This is the Information from the readme:If you have only one STM32 Nucleo board, you can program it as SERVER and use as CLIENT the BLE IOT app for Android devices available on the Play Store at https://play.googl...

Posted on June 26, 2018 at 01:53Which pin has the LSCO function on STM32L4R5xx?I can't find it in the documentation. I found MCO available on pin PA8, but can't find LSCO.
Posted on June 26, 2018 at 18:39Hi,Why there is no HAL_QSPI_TransmitReceive() function like HAL_SPI does?Thx
Posted on June 25, 2018 at 20:08Hello,I have the problem that apparently PA9 is in HIGH state after applying the supply voltage to my circuit.The problem is, that it is connected to the gate of a N-Channel FET which you can see in this image shorts ...
