dear all,I keep studing the STM32H7 architecture and this time I am trying to control a DAC using DMA which seems an easy task. However, in my case, the output is always at zero. I have used it without DMA and it works, therefore my HW debugging work...
Hello,Recently I started using c++ application with STM32, and I encounter a very strange behavior:It seems that after 1-3 calls to new() operator the new operator call get hang somewhere into assembly. When I try to step into the problematic new cal...
I am try to connecting a STM32 Nucleo (F401RE) to a ESP8266 on UART.I've managed to control the ESP8266 with the PC using a usb/uart channel and hyperterminal.I've managed to send uart messages to the PC from the NucleoBut I am unable to command the ...
We have a driver for the RTC which I am trying to enhance with sub-second resolution.I am testing with a tight loop which is repeatedly reading the time. First I am reading the SSR register (which should 'lock' TR and DR?) then the TR, then DR (to 'u...
Hi,In one of my project I am using STM32H750 controller.I want to measure the pulse width which is an input to the controller whose width will be in some nanoseconds so I want to configure the timer in a way that it can support to start the count fro...
HelloI use STM32L100.I try to use the clock output from the MCO as the I2S clock.STM32L100 is an I2S slave and outputs an external clock using MCO(24.5MHz).Can it use without problems？Thank you.
Hello, I'm working with F746ZG Nucleo board with fw package STM32Cube FW_F7 V1.15.0. I seem that the included user manual UM1905 is not updated: C functions related to the CAN described in the document don't correspond to the function interfaces defi...
Dear experts,A customer asks me to copy application from flash to RAM and run in RAM.Not sure if this is justified. If I remember correctly it is not so much on 'F4, but maybe on H7 RAM performs much better? Anyway they pay for this so...I've created...
I try to measure instruction throughput with the following snippet:float bench(int tries, int repeat) { uint32_t t0, t1, d = 0; unsigned A0, A1, A2, A3, A4, A5, A6, A7, B = 1; A0 = A1 = A2 = A3 = A4 = A5 = A6 = A7 = 0; for (int i = 0; i < t...
