Difficulty Exiting SWIM Debug Mode
Hello,I'm currently encountering an issue with my project, which is used to load .s19 files onto target devices (specifically STM8) via the SWIM protocol.Previously, the functionality was seamless when there was no external power supplied to the targ...
STM8S103 not understanding interrupt priority.
Hi,I do not grasp the STM8S103 interrupt priority philosophy. Each Io-port can be assigned to 1 out of 4 priority levels called level 0, 1, 2 and 3 page 68/467 of the RM0016 reference manual meaning highest number is handled first. I connect a slow s...
Resolved! programming STM8S103 through ST-Link V2
ST VP Configuration - ST-Link - USB - SWIM - STM8S103F3I have connected the "SWIM" and "GND" pins of 'ST-LINK V2' to the development PCB includes "STM8S103F3", the supply from the mobile charger is connected through the USB port of the PCB.When I sel...
Resolved! Logic for checksum of s19 file in stm8 stvp
Hello. I am trying to modify my s19 file which is generated for stm8 using stvd and cosmic c compiler. Consider an S19 file which starts from 0x4000 address [EEPROM starting address]The first two lines would be : S123400000000000000000000000000000000...
Resolved! Marking STM8L151F3U6TR
Hi, I have bought the parts STM8L151F3U6TR. The marking indicated in datasheet is L526. However, marking on component is L536. Anyone can confirm this marking of L536 is correct?
Unknown TSSOP-20 chip identification
Hi all.I'm struggling with certain device and I'd like to identify unknown TSSOP-20 chip on the PCB. Chip must be an MCU and based on the pinout it's very close to some STM8, eg. STM8AF6213. There are VCC and GND connected to Pin 9 and 7 respectively...
IWDG STM8
Hello,STM8S208RB microcontroller, Independent watchdog (IWDG). After starting the watchdog timer (command KEY_ENABLE value = 0xCC), I understand that the watchdog timer stops after resetting the microcontroller. The default register state is undefine...
My first ever PCB design. Any comments? Tips or tricks?
Hello stm community. I am designing my first ever PCB board and i need some comments of yours. Here is the screenshots of the pcb schematic and pcb itself. Do you see any mistakes etc? Also I am not sure about the VCAP connection. Is it correctly mad...
