Hi,I am trying to set up two timers so that they generate a PWM with the second timer being 1/4 phase past the first one. I am using an STM32F446.I have the second set up as slave and triggered by the OCREF2 of timer 1, this should then generate a re...
I have a distance laser outputting at 10KB/s (BAUD 921500). I cannot miss any of the information output by the laser so want to turn it on after the UART DMA is turned on and listening.Hence the steps areStart UART DMA Start laser However, doing thin...
Good morning everyone,Sorry for the (maybe) silly question. For a new design we would like to exploit the STM32H733ZG microcontroller. From its datasheet it seems that it supports a 16-bit SDRAM, and for our application it should be at least 16 MB la...
I have a requirement to use DS1820 temperature sensor in parasite mode, that needs 5V power supply (2 wires only) and STM32 MCU.It works with 3V3 power supply, but there is increased measurement time, and it stops working over like 80°C.I guess durin...
Hello, I am using a Power Management IC with Digital output supply specifications in my project with very low power. The average digital outputs are: 1.8V, 85uA, 150 uW.I am struggling to find a suitable low power MCU. Any suggestions?For example, I ...
Hi,I have spent a few days trying to get the timers in sync, that is use one timer with multiple outputs; oc,PWM,base. I am generating a 1MHz clock for an external device. And then a start pulse. When the timer overflows ADC starts. It needs to be ex...
Hello,I use STM32G0 and USART2 in IT mode or DMA mode.When the mcu receive a break command on uart line, he reset after entering on the IRQ handler.Have you an idea ?Regards
Hello all,I have been working on an STM32F0, with an external ADC. I used PA5 as an SCK with SPI1_SCK, PA6 as an SDO with SPI1_MISO, and PA8 as a CNV with TIM1_CH1. With one external ADC, it all worked as intended. I used an oscilloscope to confirm t...
