HiI am trying to integrate maxbotix MB1003 sensor onto Nucleo L073RZ board. Nucleo board is running mbed OS. After few hours of proper operation, ultrasonic readings get stuck at a particular value like 420 mm. Sensor operation is simple triggered op...
Hello,i am facing problem with flashing my STM32F769I Disco. the flashing works when i change to erase full chip instead of sector erase on Keil MDK 5.Full chip erase takes longer time as usual and i dont prefer full erase every time.The project is a...
Posted on May 19, 2018 at 22:56Hello,I am currently using the OctoSPI RAM on the STM32L4R9I-EVAL board (IS66WVH8M8BLL-100BLI (Hyperram)).At first sight everything looks as expected, but when I read and than write with 8 bit access, only every second...
Hi I am using a stm32L433 100 pin with an external 2.5v reference chip connected to vref+. I have tried placing a voltage (tried different values) onto one of the a/d channel, but the result is 40mv low. I then programmed the D/A , which uses the ...
I'm using Windows 10 and arm KEIL IDE along with STM32F407G-DISCOVERY board. I'm a very beginner and trying to do something with LED. I'm stuck at the initial stage itself. I have a problem with the LED API in the Board Support Package in the set...
Posted on April 13, 2016 at 23:25Hi,I facing problem with custom segment glass LCD interfacing which include 4 COM pin and 20 SEGMENT pin with 1/4 duty cycle and 1/3 bias (Refer Attachment).I tries to understanding HAL library provided on ST site ex...
Hi guys. I designed a simple PCB for measuring the battery voltage of a biomedical instrument. But I faced a simple problem. I use HAL to generate the code. So when I set the ADC clock in Asynchronous clock mode the while(1) is not executed!!!IS it b...
I have 10uF (=10uF+100nF)ceramic capacitors for VCAPs in a custom board. Voltage there is 2.7V. Supply voltage is 3.3VI have problems getting the STlink to accept the board. First I managed to erase the chip, now STLink does not even recognise the c...
Hello there,up to now i have used an Audio DAC on a STM32F407 with DMA and Half/Full Transfer Interrupts with CubeMX. So far so good.But now i am a little bit confused. As i have read some Posts it seems that it might be not possible to use Full Dupl...
