I'm developing a vibration and temperature analysis system.To do this, I have developed a sensor based on an STM32L053C8 chip and a KX122-1037 accelerometer.Looking at the datasheet, this accelerometer can reach a maximum data rate of 25600Hz, which ...
Hi all, for a projet I need to create a signal at 500khz, and every 60 µs I want to stop the toggle (or not) I generate the signal with the output compare of tim2 (on stm32L073)then, in TIM2_IRQHandler(void)I try to count the number of call, then st...
I'm developing a vibration and temperature sensor solution for industrial machinery.Previously, my system was equipped with Atmega 328p chips, but it has now been upgraded to an STM32LO53C8T8 chip.The circuit has a LoRa radio for sending signals to t...
Hello, I would like to know if anyone has already encountered this problem. I have an LPTIMER configured with an ARR Match interrupt at 100ms I also want to enter my interrupt every 10ms so I added an interrupt in compare mode at 10ms.I have 2 questi...
I am making this code which, on an interrupt, is supposed to wake the system from STOP mode, put it into low powered run mode, and run LPTIM1 for 1 minute before triggering a flag and going back into STOP mode. I have PSC as 128 and ARR as 60962, so ...
Hi all,I am trying to send x number of 100 ms pulses (50 ms on, 50 ms off) with a PWM in one-pulse mode. when I wired the output to a pulse-counting device, I noticed that it is picking up 10x less pulses than is programmed. I believe there is an iss...
Hi. I am using STM32L010C6Tx. I want my microprocessor to sleep for 10 seconds after processing. I want to use Sleep Mode. I don't have any interrupt pins. I want it to wake up after 10 seconds. How can I do?
Hi there,I've been using the NXP Kinetis MKL03Z32VFK4 Ultra-Low Power Cortex-M0+ MCU in our products, and it's been working well, but due to a major redesign, I'm looking for alternatives, and ST MCUs are promising.Specifically, I'm concerned about l...
I have a system of sensors connected to an STM32 chip, all working via I2C and 3.3V.I've created interface libraries for my sensors, specifically the temperature and accelerometer ones. However, when I read the values measured by the sensors, I came ...
Hi,We have a STM32L031F6 which is used as an RTC. A weird phenomenon is occurring: when the controller goes to sleep, it only uses 2µA, but after 2 minutes and 40 seconds, it starts consuming 50 to 100µA, depending on the hardware board used. There i...
