is the i2c init function right?

void sEE_Init(void) { //printf("i2c init\n"); sEE_LowLevel_Init(); // enable clock   /*!< I2C configuration */ /* sEE_I2C Peripheral Enable */ I2C_Cmd(sEE_I2C, ENABLE); I2C_DeInit(sEE_I2C); /* sEE_I2C configuration after enablin...

Strange tim4 interrupts?

The chip is stm8s103f3p6, and I wanna use lsi as clk and tim4 to make a timer, there are two strange things happened.​ when I set prescaler to TIM4_PRESCALER_4 and ARR to 32, I thought it should interrupt every 1ms (128k/4/32=1kHz), but it seems brea...

Hi,​I​ am developing an IAP for one of my project.In that the bootloader and the application using interrupt vectors.How can I seperate the ​interrupt vectors for application as well as bootloader. How to relocate the interrupt vectors in STM8?​T...

Issue with STM8S103F3 using wait for interrupt assembly call

Hello,First off, I'd really like to thank the community for being there to help, and I really appreciate any help or guidance offered. I am trying to put an STM8S103F3 MCU into wait mode until an external interrupt on port A triggers. I make the asse...

STM8S001J3 halt mode current is 4.5uA in datasheet, I get 1mA when tried

1. Table 26 of STM8S001J3 page 49 of 85, shows current consumption in halt mode is 4.5uA typical, but when I put MCU in halt mode, i got current in 1mA range. Dont understand why?2. I have broken small breakout board from stm8-so8-disco of STM8S001J3...

I need PWM in STM8S105k6. Someone have code example?

How to detect if debugging session is active on STM8S103?

Hello,Is there a way to detect if debugging session is active (eg. IAR debugger is attached)?Datasheet says DM and SWIM registers are only accessible from SWIM interface, not from STM8 bus.Unfortunately IAR doesn't like the WFI instruction during deb...

Why does USB/Debugger Time out when running Overnight?

I am running code overnight using the STVD debugger and an STM8S discovery board as the interface. After many hours the debugger loses connection to the target. "Stop Program" is grayed out under the "Debug" menu. The "watch" variables are not bei...

ADC scan mode not working correctly on STM8S105C6 test board.

I would like to use 2 ADC channel in my program (0,3) using STM8S105C6. I tried to use ADC scan mode and tried to read buffer. it seems that it reads channel 0 and channel 3 for the first run but with change in analog volatge on both channels , only ...
