I'm still having problems with VBAT current consumption. I've loaded my firmware and the processor behaves correctly in all other respects. I removed all components from the processor to insure that there are no sneak paths for parasitic current dra...
Hello,My adc clock is 140.625 KHzMy sample time is 239.5 CyclesSo my Conversion time = 239.5 Cycles + 12.5 Cycles = 251.5 Cycles.1 Cycle = 1/Adc Clock 1/140.625 KHz = 7.1uSSo total conversion time = 251.5 * 7.1uS = 1.78msi.e my sampling frequency = ...
I've written a benchmark test to compare the CPU execution time for float adds versus int32_t adds. The results were surprising. The benchmark is very simple, a loop of 100 million is created and timed so that it's value can be subtracted from othe...
Hello,My objective is:Read voltage in 10 channels of Blue pill using Scan and Poll conversion mode.Problem I face is:Wrong values are read. When I feed 3.3v to the adc input (any input), its adjascent channel reads 3.3v, but that too changes to 2v. ...
I have purchased through Amazon 2 epaper displays from Wisebatt1.54 inch bi-color (black/white/red) 2.13 inch mono color display with HAT interface boardFor the first one, the black was ok but the red was shrunk to 1/4th top left quadrant of the disp...
Dear Members,How can I count a pulse from a sensor with timer ?How can I calculate the period of this pulse ? samplebuff[i].ired = buffer_rx[ j ]; samplebuff[i].ired <<= 8U; samplebuff[i].ired |= buffer_rx[ j + 1 ];betweensamp...

what is the behavior for stm32 reset pin reset? it will output 0x00 after reset pin changes to high?when it is reseting, the usart tx is low level?
