Hello Everyone, I am using the STM32F777 and utilizing its RTC and external 32.768 crystal(LSE).Currently I am having a drift of 79s in 76 hours. it is a little bit less than a second per hour. It is not that bad but I would like to have a better res...
Greetings From Turkey, We have a hardware using stm32l471. We wake up at certain times and send data to the server. Then we go back to sleep mode.Here is the our callback to switch to low power consumption mode.void low_power_callback (int time) { s...
Following in the directions of this post, I am able to reserve and write to (and read back) from a section of FLASH dedicated to calibration data. However, when I reprogram the device, the IDE wipes the whole memory clean before programming and we lo...
Hello,I am trying to read single ADC channel using NUCLEO-H743ZI2 board but the result is wrong. I have created a very simple project using CubeMX. Kept the default Clock setting. Enabled ADC3 CH0 (PC3_C Pint) in single ended mode polling. Enabled UA...
I am using a STM32F446re to detect rising edges, calculate the frequency and execute accordingly.I have two signals that need to be detected. So I use two Timers 3 and 4. My frequency ranges from 3Hz to 300 kHz so I need to use overflow detection.How...
On F1xx and F4xx platforms, I have been using the GPIO pull-up resistors for the connections to OC hall sensors used in BLDC motors. There has never been a problem. With STM32H750, I can see that the PUPDR register has the right values for the pull...
I'm trying to figure out the battery consumption of an STM32F746. Accodring to the datasheet, that depends on SRAM state, RCC state, and if the LSE is in low, medium low, medium high, or high drive.I have no idea what these kinds of drives are, nor ...
The bio reactor has bone marrow inside of it and this is being analysed for the properties of microgravitation.I would use a NUCLEO-F303K8 microcontroller. The system must endure a maximum accelaration of 10G due to the fact that it will be used late...
I'm using input capture with a 16 bit timer to read a 1.5ms pulse that occurs every 20ms. I can see on my scope that the input pulse conforms to this exactly. Here's the code for the interrupt callback:uint16_t pwmVal0 = 0; uint16_t pwmVal1 = 0; ...
