Discuss hardware and software design challenges, including NOR flash storage, OTA updates, component ID, and thermal management.
My current design has +5V connected to an optocoupler output pin, the other optocoupler pin is connected to ground through a 25k resistor. (External pull down) The connection point between the optocoupler and the resistor is connected to the MCU pin ...
Hello,I need to make a measurement with a photodiode 100-300us after a high power LED blinks for 100us. Although I feed the LED from a separate LDO (I also tried SMPS), the collapse and recovery trend in the LED voltage creates the strange shape at t...
GreetingsI'm using an STM8S003F3 TSSOP20 (my first STMicro) for a simple project with one input (low frequency PWM) and one output (high frequency PWM). I seek to keep it as simple as possible. Since I'm not familiar with STMicro MCU's, I would like ...
About Cin of LDK320What is the manufacturer's recommended value
I accidentally came across a long-discontinued NE555N timer on sale. The price is terribly high, but they are sold in a very old and respected store in my city. I decided to buy for the sake of interest. Please tell me how to recognize a counterfeit?...
Hi ST team,I referred the Application notes from the ST's for RTC temperature compensation Using STM8AL3189 MCU , Which has both positive and negative ppm compensation using CALM and CALPFrom the APP notes, ACC(ppm) = crystal deviation + k * (T -T0)^...
CubeIDE 1.7Windows 10We have used TrueStudio 9.3 for years without issue but because we began using a new ST STM32G070 processor, we needed to change to ST's version of CubeIDE. We have it building the project(with low level drivers included) but if ...

In documentation for timers on S103/S105/S003 it says that bit URS or register TIMx_CR1 should allow that CNTR=x or EGR |= UG update the timer counter WITHOUT setting the UIF flag: TIM2:URS: Update request source0: When enabled by the UDIS bit, the U...
