Resolved! AN4207 Single ended zero reference mode
Hello.Reffering to AN4207(Doc ID 023945 Rev 1) Single ended zero reference mode (Page 9):This mode injects an input common mode of half scale to the ADC thus maintaining the dynamic range the same as in differential mode (-32767 to +32767). In this m...
Resolved! STM32F103 timer interrupt fastest time is less than 1us?
I use STM32F103CB in my project. but I found timer interrupt fastest time can't less than 1us. Timer prescaler is 0, up counter mode, counter period is 36, no inernal clock division and auto-reload enable. When timer interrupt occur. I set Pin high ...
Proposal: Add lead-time estimate to McuFinder
Lead time for many parts get into the 52 weeks region. It would be helpfull, if McuFinder would give a lead-time estimator, e.g. green for good, yellow for > 4 weeks and red for > 26 weeks.
The timer input mode is not working. (using STM32F103RB)
Hi all,I test the timer input capture mode. The input range is 1Hz ~ 100Hz.I set the parameter as below. (Using CUBEMX)Timer Clock : 60MhzPSC : 6000ARR: 10000void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { HAL_GPIO_WritePin(LED_PORT, IN_...
Hello, can I use the external flash as a micro memory bank?؟؟ To do a firmware update
I want to update the firmware and my micro is a single bank flash memory. Is it possible to do a firmware update with this micro ?? Or should it be dual bank flash memory ??Can I use AT45DB321 as a second memory bank ??
