How to use STM32F100 to measure a sinwave's frequency by input cature mode of TIM3 ? ​I would like to measure sinewaves of three frequency, 39Khz�?40Khz and 41Khz.Voltage level (0V​-3V)The 39khz period is 25.64us.The 40khz period is 25us.The 41khz pe...

STM32F100C8T6 can't generate sinewave of correct frequency

2019-01-27
The chip I am using is STM32F100C8T6.  I want to generate a sine wave with 40Khz between 0 to 2V ,but I cant't get correct frequency. I have finished reading STM32F100 datasheet (RM0041) and AN3126,AN4566. After that,I am writing a program based on t...

the Flash of STM32F100C8T6 is 64K or 128K ?

2018-10-15
I have a product that needs to write parameters to Flash.I saw on the website and datasheet all tell me STM32F100C8T6 is 64K Flash,Flash 1K per page, total 64 page,the finnal page is page 63,however I made a fault I made a fault I write parameters t...
