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...

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 ...
