On the STM32L4R5 I'm seeing unusual results reading a signal from the differential input ADC1_IN5 (Which uses ADC_IN5 / ADC_IN6 pins). When I apply an identical voltage to both differential pairs I see the reading vary with voltage, but the differen...
Hello,Is there a cmsis driver for uart ? I build with stm32cubemx, but I did not find any cmsis files for any driver (I also don't see in cube anywhere we can state that we want to use cmsis driver)I also did not find it in examples of stm32cubeh7:en...
I'm designing an embedded PI controller using a STM32 Nucleo board. In the PWM configuration, a 0 means 0% duty and 800 means 100% duty. The objetive is to regulate the speed of a PMDC motor, i.e, to keep the RPM under load variations. I'm not sure y...
HI ,I have implemented USB Host facility in my custom board which has STM32F429IG MCU , My application does detection of USB stick and reads the image binary from there , where as The functionality works as intended only with some USB sticks and also...
I'm working on STM32L452. I found I2C interrupt is blocked when flash erase occurs. I have checked that I2C IRQ handler is in RAM. The vector table is also copied and used in RAM. How come the I2C interrupt is blocked. I have gone through the flash e...
Hi,I'm trying to power a STM32F746G-DISCO board from the CN6 VIN pin.I have a voltage regulator that output 11VDC current.The screen turns on but the program never start and LD6 and LD3 become red after a few seconds.I measured the current between GN...
I tracked this variable using STMStudio. See picture attached. I want to get those values to plot them in MATLAB. I tried creating an array, but STMStudio seems to have latency problems with updating a large array. How could I achieve this?
Hi,I have a Nucleo STM32F767ZI with a X-Nucleo-PLC01A1 and a test application that cyclically switches ON/OFF the outputs .All works fine when I use HSI, with Output LEDs that stay solid during ON state.If I use High Speed Clock (in Cube MX, PCC->HS...
Posted on March 14, 2018 at 13:28Hello there,I am using STM32L4 series MCU and I am trying to interface with a M25Q Micron memory using QSPI. Following the examples given from ST I have noticed that there are no HAL functions allowing registers read...
Maximum CPU freq. with 3.3V power supply for STM32H7 series is 400 MHz. Is it the same for 1.8V?
