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...
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?
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...
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...
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...
Hello everyone!I have a question and seek your help: I use STM8S005K6T6 microcontroller and cc1101 RF transceiver module, and the operation at 433 MHz is affected. It generates power automatically and can only last for 10ms. The voltage remains at...
Hi,i have STM8L101F2 at breadboard. Decoupling capacitors 100nF+22uF, supply voltage 3.3V from linear lab.power supply, nothing connected to any pin. Simple firmware (Cosmic compiler)void main(void){ GPIO_Init(GPIOA, GPIO_Pin_All,GPIO_Mode_In_PU_No...
Hello. I am using the STM8S001J3 MCU. I want to use the reset function in my MCU. stm8 has a total of 9 Reset functions.●External reset through the NRST pin● Power-on reset (POR) and brown-out reset (BOR): During power-on, the POR keeps the device un...
Hello,STM8S208RB.How can you read the AF bit in the I2C_SR2 register?When I try to read this bit, it is always 0 even if this bit is set to 1 (In debug mode I look at this bit that it is set to 1). For example, the following condition always gives th...
Hello everyone.I am in trouble with the datasheet of STM8AF5288.There are only brief descriptions about TMU in the datasheet.What is the difference between TMU and ROP?How to use TMU?I can't find any documentation.Does anyone have more detailed infor...
