STM8 MCUs

I would like to know how to use any timer, say TIM2, and GetCounter() correctly. I'm using SDCC on linux and compiling for an STM8L051. Please see some example blinky code. Below is the code I think should work. Any help is greatly appreciated.

void main(void) { uint16_t tmpcnt = 0; uint8_t tmpcntrl, tmpcntrh;   setup_pins();   CLK_PeripheralClockConfig(CLK_Peripheral_TIM2, ENABLE); TIM2->PSCR = TIM2_Prescaler_1; TIM2->ARRH = 0; TIM2->ARRL = 1; TIM2->CNTRH = ...

STM8S005K6 I2C Bus always busy

Hi.Regarding I2C Bus busy problem. I am using alternative pins (PB4 and PB5), as I have the small chip with fewer pins.Option bits are set, and verified.However even at power up the BUSY bit is set. It is set through configuration of the I2C peripher...

I2C Read from Slave with Python

Hi,i use a stm8s003 and SPL for programming. I am not a profi programmer.My goal is measure an Analog signal with stm8s and reading this with Python command from a Raspberry Pi.Ok, i use STM example Program I2c slave. I can read some registers from s...

can i interface and operate 16*2 LCD display directly with STM8S003F3P6 controller's GPIO pins, without any external display Drivers? if yes kindly share demo code/link/manual/application note or project.

if yes then please share technical article/code/project/link etc.
