STM8TL52 current consumption in Halt mode about twenty times higher than expected

Hi. I'm using an STMTL52F4 20-pin MCU that I've programmed to immediately enter HALT mode on startup with the halt() command. Although the documentation says that the chip consumes only 0.4uA in this state, when I put a multimeter in series with the ...

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...

Why is the Halt() function not working?

#include <stm8l15x.h> #include <stm8l15x_pwr.h>   void main(void) { GPIO_Init(GPIOA, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Fast); GPIO_Init(GPIOB, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Fast); GPIO_Init(GPIOC, GPIO_Pin_All, GPIO_Mode_Out_PP_Low_Fast); ...

Failure to open an include file during release building in STVD 4.3.12

Hi. I'm using STVD v 4.3.12 with an STMTL52F4 MCU. Debug building works just fine. However, when I switch over to a Release build (changing nothing else), it fails to compile, reporting that it can't open an include file it was able to find before. C...

stm8_segment LCD problem

We are developing a product that uses segment_LCD using stm8l052r8.There was no problem when developing with com4+seg28There was a problem when developing with com8+seg24.When you turn on the entire screen, all the text on the screen comes out well.I...

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.

Is it possible to generate 114khz frequency on stm8s gpio pin

What is the proper code for STM8S External Interrupt?

Being new to STM8 development, I'm having a problem getting the external interrupt to work. There are many bits and pieces of external interrupt code I've found on the internet, but I haven't found a definitive piece of code that works as expected. H...
