Hi,Am using blackpill with F411 mcu at 100MHz, with Timer1 configuration:Clock source: internal clockPrescaler: 9999Counter period: 9999So Timer1 ticks every 1 second (1Hz)void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { secEllapsed++;...
Hello, world. I try to find answer how read that code: 2020L. Full text on chip are: M27C801 -100F1 52987 -2020L SINGAPORE That 2020L need read like: WWYXX? Or YWWXX? Thank you for answer. Regards
We are using the TDE1798 (500 mA power switch) as a digital output (DO) driver on our controller board. The connected load is a 24 V DC valve rated at 16 W, which corresponds to a nominal current of approximately 667 mA. However, the measured steady-...
(Sorry, I am not a pro and the Google search AI is braindead.)I am just nerding out over FERDS at the moment and want to build a SMPS using them.
Hello Team,We need to interface a CT with a microcontroller for current measurement. The required measurement range is 0.01 A to 60 A with a 10 mA resolution.Please find the attached block diagram for better understanding. We require the reference ci...
Moved from the STM32 MCUs forum - this has nothing to do with MCUsFor this circuit, how can I implement the tactile switch functionality using the dual-LED feature? Can any one explain how the circuit should be designed for a 28V input? I am unable I...
To whom it may concern: I am looking at your STEVAL-IPFC12C1 evaluation board schematic and there is a part that doesn't make sense to me. Why would "GND_BRG_SW" be connected to V_INPUT? Are you not connecting low voltage line to a high voltage line?...
Hi ST community i just searched the GUI for EV-VNF9Q20F but could not find it. Please tell us where can i get suitable GUI. and also i'm really glad if you could check the availability of SPC582B against EV-VNF9Q20F.
Greetings, I'm trying to set up TIM4 per the reference manual (RM0016).With the clock set to LSI at 128kHz, the following code causes the PD2 output pin to appear constantly high visually via a wired LED. I would expect it would be blinking once per ...
Hello, I'm curious why TIM2 is correctly repeating in my code, whereas TIM4 with equivalent settings is not.In this code, the TIM2 indicator (fired by the TIM2 interrupt) is blinking twice a second (clock set to LSI, meaning 128kHz). I would expect t...
