Posted on March 28, 2018 at 11:45Hi !I'm currently using STM32F413 uC.I can not find on the datasheet (and the reference manual) the output voltages of UART pins (or even GPIO).The voltage of course depends on the supply voltage. I'm currently power...
Posted on March 23, 2018 at 13:11I ported u-boot 2018.03 to my own board based on stm32f767igt,i set some register with systick timer as below:as the above picture, the systick timer count is changed,but i couldn't get in systick handler?besides reg...
Posted on November 07, 2017 at 15:49 Hello. I have problem with i2c device which requires time courses as showed below. This picture shows writing data to i2c device, in this case ltc29 In first approach I try to do this in 2 steps, send add...

Posted on March 28, 2018 at 04:38I'm using stm32f051R8Tx(stm32f0discovery) and I'm trying to connect with i2c devicesI used HAL-driver that CUBEMX provides and i succeeded to communicate with i2c LCD device(LCD1602A).LCD works really well.However, ...
Posted on March 28, 2018 at 10:35Hi eveerybody,I'm tryng to use the protections against unwanted write/erase operations reported on 3.4.3 of Reference manual.When my program runs the memory is locked (PELOCK BIT = 1) and i want to unlock it.There is...
Posted on February 08, 2017 at 05:37Hi,It's not so easy to find cheap compatible ST Morpho connector.Here could be a place to list them.Thanks,Eric
Posted on March 28, 2018 at 08:46Hi,I just wanted to verify if STM32F051R8T6 has an option for internal signal amplification with adjustable gain(ofcourse, within 3.3V range) of an input signal(in varying mV range) to any ADC pin. I am aware that it...
