Posted on January 11, 2018 at 17:21Hi,My stm32 opamp characteristics understanding is that- max output current 500µA in normal mode, stand-alone- min output impedance 4kR in normal mode, stand-alone.This last value fairly aligns to considering a se...
Posted on March 08, 2016 at 12:55 Hello, I'm having problems with STM32L100RC I2C1 peripheral on PB6 and PB7. The lines are pulled to MCU Vcc with 1k resistors. The problem is that when I configure the PB6 and PB7 as I2C1 pins, the MCU pu...
Posted on June 06, 2017 at 06:24When I studied electrical engineering in college years ago, I worked on a development board with my school from Motorola. I was able to do a lot of things with it because the teacher and my textbook explained to us h...
Posted on September 29, 2017 at 15:22Is there a bug in the HAL driver lib FW 1.1.0 ?Because SPI4 is not supported.In the routine HAL_SPI_TransmitReceive there is a question'if (IS_SPI_HIGHEND_INSTANCE(hspi->Instance)) ...'the else branch is empty/no...
Posted on January 11, 2018 at 09:11Hi, I have a micro STM32F011F4 and I try to write in EEPROM via SWD but cube programmer shows an error message (also from CLI) how can I write in EEPROM? (STM32 STlink utility works well) Thank youMarco
Posted on January 11, 2018 at 11:17Hello,i want to use an USB OTG with an automatic host device detection. CubeMX (L4) doesn't support it and there is only one example for an evaluation board with a display to select the mode (host or device).Is an ...
Posted on January 11, 2018 at 06:10I am using an stm32f3 discovery board. I have been having various problems trying to connect to the board consistently. During an attempt to solve this, I accidentally ran the firmware upgrade (stsw-stlink 007). No...
Posted on January 10, 2018 at 10:31Hi, I am just starting a project in STM32.Now we have a confusion on which IDE to select SW4STM32 or Atollic TrueSTUDIO. Recently ST acquires Atollic. Now eventually one of them become obsolete soon.Please share yo...
