LIS3DH Auxiliary ADC using STM8 is giving constant value

HiI am working on a project where we are reading the battery level on the ADC1 of LIS3DH. This value I need to read using STM8L051F3P. I am using SDCC compiler. I am able to read the WHO_AM_I register. I am also able to set the accelerometer threshol...

application note AN3281 to implement the I2C bus for the STM8S microcontroller.

You have published an application note AN3281 to implement the I2C bus.Where can we download the example programs described in the note? Thank you for your answers

J'essaie de faire fonctionner le bus I2C sur STM8S207 avec SPL, toutefois le flag I2C_FLAG_BUSBUSY reste toujours à 1 vous trouverez mon programme de test sur

I2C error handle in cosmic compiler.

Hi there.I´m using a STM8S207 with cosmic compiler.I am reading and writing a 24L64 eeprom thru i2C and everthis is working well.But i want to put protection in the routines to avoid lock the program in case of fail of a write or read command.i found...

I2C register I2C_SR3 in the field BUSY getting stuck in High level

I am having an issue with the I2C communication between the MCU STM8208C6 and the Ambient Light Sensor APDS 9306-065.Before any setting is set up during the debugging, the I2C register I2C_SR3 in the field BUSY is 1.• I checked if there was any short...

MCU restarts after I2C->CR2 |= I2C_CR2_START; during setting I2C_GenerateSTART

I am trying to get I2C communication working between two STM8S003F3P6.From I2c master I am trying to initiate I2C start message using CR2 registers with below code#define I2C_CR2_START ((uint8_t)0x01) /*!< Start Generation */   .....   I2C->CR2 |...

STM8S I2C master crashing on I2C_GenerateSTART(ENABLE);

I am trying to run example code for i2c master and slave, provided in Stm standard peripheral library from https://www.st.com/en/embedded-software/stsw-stm8069.htmlBut the master keeps crahing at I2C_GenerateSTART API call.I2C_ITConfig enableInterru...

How to check open drain pins PB4 and PB5 working properly for I2c communication [STM8S003F3P6]

I am trying to get I2C working for STM8S003F3P6 with ESP8266. I tried I2C sample code available with standard periferal library https://www.st.com/en/embedded-software/stsw-stm8069.html . But for some reason I2c is not working. Now I just noticed the...

Fix I2C ACK delay

How can I fix the super long delay and weird ACK glitch with I2C on STM8S?I'm having some troubles with I2C communications between a raspberry pi and STM8S. The STM8S is a slave transmitter and I2C is running at 100 KHz. It works much the time, but I...
