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...
Hello,I have STM32L152RET6 IC attached on my board(Pos_Est_Rev_0), and I'm using NUCLEO-L152RE board to debug/run the firmware.I'm trying UART communication by USART channel, but the following symptoms are found :1) When the debugger arrives to the l...
I would like to use the integrated Bootloader of the STM32H743 for updating the firmware over I2C. I don't have access to BOOT or RESET pins at the I2C master side, so my desired procedure would be:Send a command over I2C to my firmware. Once my firm...
Same question for pin PF14: can it be used as a single-ended ADC channel using ADC2_INP6 ?The Cube does not indicate if these pins can be used as single-ended ADC channels.Thank you.
Hello,I need to fill the stack with watermarks, but I do not have access to the assembly startup script. Usually I would do it right at the start of the reset handler, is there another way of doing this?
