STM8s003f3 with i2c LCD (PCF8574AT I2C Module)

Hello Every one ,I am trying to use I2c based LCD with stm8s003f3 controller. the write i2c address is 0x3f I am struck at a point ,the code is stopped in endless loop in below functionvoid PCF8574_write(unsigned char data_byte){  I2C_GenerateSTAR...

How to link to lin.lib from en.stsw-stm8a-LIN in an STVD project

I have followed the steps to create my lin.lib file from my LDF, but I need to add it to a STVD project, not one built with an extrenal makefile. I have tried adding the library to the default compiler path, and tried specifically adding it to the pr...

STM8: mistake in Programming Manual?

The PM0044 for the STM8 MCUs explain that data address space is 16MBytes linear. Ok, so why on the page 19 data address to a RAM memory has 16-bit wide (A15...0)?

Will high temperature disrupt the code and make the IC malfunction?

My stm8l151k4t6 malfunctioned after I detached it from PCB in some heating way and then welded it back to the board. I wonder if the temperature I used to removed and welded the IC is too high. Anyone ever met this situation?

Sawtooth waveform on NRST

I have been using a STM8S105 successfully for a few months and recently, I have been experiencing problems with i/o on UART2. When I eventually probed the NRST pin I noticed that there is a sawtooth waveform on that pin, with no other circuit connect...

STM8L052R8 power (current) consumption problem

STM8L power (current) consumption problemPosted on August 23, 2011 at 06:42 I'm developing an application with STM8L052R8 MCU now, and this application is battery-used product. The problem is that, I cannot make the MCU consume micro-ampere order cu...

Timing a button press on STM8S001J3

I'm trying to measure the duration of a button press using TIM2 as a counter. I have one of the buttons triggering an interrupt which enables the timer on the positive edge, and then calls TIM2_GetCounter() on the negative edge.I'll save you all a bu...

I am using multiple external interrupts and timer/adc interrupt in my code.Code gets reset when data comes over PORTC and PORTD and ISr are executed. Also TLI interrupt is enabled in system.
