STM8 MCUs

Need to write and read reliably to a protected block of EEPROM memory from startup to startup

Hi. I'm using an STM8 MCU. I'd like to reliably write to and read from a block of EEPROM/FLASH memory (about 1k) that will never be overwritten either by the MCU or by programming/debugging via SWIM, but can be read and written from code. I'm writ...

Problem CAN_ReceiveAll in standard peripheral library

I develop stm8 using cosmic compiler and v.2.3.1 standard libary.I think there is a problem with the definition of CAN_ReceiveAll.In this function I can get an address of _Data variable.But, I can not get the address in Caller side.My thoughts should...

STM8S103F3 programming in assembly language.

Hello,I am newbie in ST MCU.Before ST MCU i use Microchip MCU lot. I am mostely using in assebley language code because i wote code for SMPS.In microchip there is good IDE and they provide a lot example with comments to learn easy.While i get very di...

Hi, I have started working on STM8L Dev board. I want to integrate HAL driver. Can anyone tell where I can find this?

hi. I'm using stm8001j3 but I have problem with timer 2 and 4 .I have enabled clock for this timers and do all setting but it doesn't work it seems that clock is disconnected .can anyone help ?

 Timer 1 work's well without any problem.the code works properly with stm8s105k4 without any problem.

Can one generate an interrupt from Port C pin 0 or pin 1 on the STM8L051F3?

There do not seem to be definitions for Port C to be used as such.  //EXTI_SelectPort(EXTI_Port_C);  //EXTI_SetHalfPortSelection(EXTI_HalfPort_C_LSB, ENABLE);  //EXTI_SetPortSensitivity(EXTI_Port_C, EXTI_Trigger_Falling);Is there any way to trigger a...

STM8S UART2 Std_Periph Continuous Rx Data Reception

I have implemented the same methodology as explained in the below post:http://embedded-lab.com/blog/continuing-stm8-microcontroller-expedition/12/I am trying to receive data that is 6 bytes long on the Rx pin using interrupts. When calling ReceiveDat...

In the design, I am using STM8AF6286 controller and want to connect 2 slaves over 1 SPI but with 2 separate chip selects. But STM8AF6286 having single chip select pin. what should I do? is there any other controller in 32 pin, QFN package available?

SWIM ICP programming on STM8L050j3

Hello,I'm trying to program and STM8L050J3 from another MCU through ICP programming on the SWIM interface. Section 5.6.1 of PM0051 presents a sequence where it is required to apply a reset and release it after the SWIM_CSR register hase been configur...

Set Option Bytes AFR, STM8S207RB

Hello Everyone,I am to test a device which uses the STM8S207RB as the controller. The controller's pin 25 and 26 are used for I2C communication. But in order to use it for the SDA and SCL signals, I need to remap its function by changing the AFR6 bit...
