Where is VREFINT_Factory_CONV?

I have STM8L051. In the RMThe internal reference voltage is factory measured and the result of the ADC conversion isstored in a specific data address: the VREFINT_Factory_CONV byte represents the LSB ofthe VREFINT 12-bit ADC conversion result while t...

Will high temperature disrupt the code and make the IC malfunction?

My stm8l151k4t6 malfunctioned after I detached it from PCB in some heating way and then welded it back to the board. I wonder if the temperature I used to removed and welded the IC is too high. Anyone ever met this situation?

Sawtooth waveform on NRST

I have been using a STM8S105 successfully for a few months and recently, I have been experiencing problems with i/o on UART2. When I eventually probed the NRST pin I noticed that there is a sawtooth waveform on that pin, with no other circuit connect...

STM8L052R8 power (current) consumption problem

STM8L power (current) consumption problemPosted on August 23, 2011 at 06:42 I'm developing an application with STM8L052R8 MCU now, and this application is battery-used product. The problem is that, I cannot make the MCU consume micro-ampere order cu...

Timing a button press on STM8S001J3

I'm trying to measure the duration of a button press using TIM2 as a counter. I have one of the buttons triggering an interrupt which enables the timer on the positive edge, and then calls TIM2_GetCounter() on the negative edge.I'll save you all a bu...

I am using multiple external interrupts and timer/adc interrupt in my code.Code gets reset when data comes over PORTC and PORTD and ISr are executed. Also TLI interrupt is enabled in system.

I want to download the STM8S MC FW Library Builder software , but i can't find address. can you tell me the website ? thanks

Nucleo kits for STM8 MCUs

Posted on July 13, 2018 at 16:49Nucleo kits for STM8 MCUsDear STM8 fans,Let me inform you, that STMicroelectronics extended hardware tools ecosystem available for STM8 MCUs by introducing two STM8 Nucleo-64 kits: https://www.st.com/content/st_com/en...

Have read about the STM8 Nucleo (64) STM8L152R8 and the development platform and ST-Link with this device is not communicate with software. Where is information about this problem?

Put driver update and firmware update. WIndows reports it as a drive NODE_8L152. a USB drive.ST-Link fails to find and programmer cannot read from the device. The leds are green and green.The jumpers have been verified. The upgrade said it finished. ...

STM8S001J3 ADC Maximum Input Impedance

What's the max Input Impedance of STM8S001J3? I couldn't find it on its datasheet.I've found a couple of equations in page 11 of AN2752. If I keep slowing down the clock of the ADC, would I be able to increase the maximum input impedance as long as t...
