Use of SWIM input as digital I/O

Hi everyone,I need your kind support for an issue regarding the micro STM8L050J3.In one of my project for a question of overall dimensions of the PCB (wearable device) I must necessarily use this 8-pin micro, but unfortunately I still need an extra I...

Programming error after first time

Hi,I have a problem with my STM8AF6213PDU custom board.The first time, I programmed sucessfully the board using ST Visual Programmer. The procedure was succesfully because I loaded a "blink firmware" and it's always working (ever with power on/off)No...

Enabling interrupts

Hi, I'm new to STM8 (usually I develop from STM32) and I'd like to know how can I enable interrupts.In STM32, I usually configure the peripheral interrupt enable bit and also in the NVIC I enable the interrupt to pass it from peripheral to CPU.In STM...

How to use the buck switching regulator ST1S03PUR, and dimension the components value for an out 3v3 and 500mA?

Hi, latelly I am trying to use the buck switching regulator ST1S03PUR and I have some problems with it. It should be something easy to do but seems like not.I have a DC Vin 12V and i want as out 3V3 and 500mA.For the Vout I am using the formula from ...

My question relates to the M41T81 Real Time Clock. Wasn't sure which topic to post in so picked this one since the RTC interfaces to an 8 bit micro. My problem is that the RTC doesn't always recover from power-down correctly.

The data sheet for this part says that after power loss the HT bit is set, and any reads of the clock will return the time of the last read. Then after the HT bit is cleared one should be able to read the current time since the clock is battery backe...

Hello, i use the STM8 32k and i have a problem, the program display errror iostm8s105.h no such file or directory, i i installation the program again but the error to be continued.

M24C04-DRE

I saw two version of subjected item at EE marketing , ​ is different on body marking , one is 404RP, the other is 404RB, so I would like to know the distinguish between them on electrical parameter? can alternative to use?

ECMF02-2HSMX6 - Change D+/D-

Hello ST-Community,we are using the ECMF02-2HSMX6 in our USB3.0 application for ESD protection. Is it possible to change the D+ and D- lines? Internally, the part should be electrically the same, but it is not mentioned.Thanks a lot Holger

Hi, I'm working on STM8S interfacing with TI's ADS1232 IC. Please help me regarding to programming code.

STM8S003F3 used in HC12 module with Si4463 transceiver

Dear Friends,i am working with HC-12 module that have inbuilt STM8S003F3 Microcontroller with Si4463 Transceiver module. that works fine at data transmission. But i am trying to upload Arduino Sketch through HC12 Wirelessly for a long distance. here ...
