Hi!There is an issue with unlocking the EEPROM on STM8 (probably all of them, but I am using STM8L151). This article summarizes the issue very well: https://slime.systems/content/stm8-eeprom-bug/There it says it was first found in 2013, and here we a...
Hi,I am looking at STM8 MCUs and am trying to figure out, if I need the RWW functionality. I want to save data to EEPROM after a specified time has elapsed and read at random times from the data EEPROM. I also want to have UART comms running.To ensur...
My code as a below;void EEPROM_WriteByte(unsigned int address, unsigned char value){ FLASH->DUKR = 0xAE; FLASH->DUKR = 0x56; (*(uint8_t *)(0x9FC0 + address)) = value; FLASH->IAPSR &= FLASH_MemType_Data;}unsigned char EEPROM_ReadByte(unsig...
Hi. I'm using the STVD IDE with Cosmic with an STM8TL52F4 MCU with the 'Minimize Code Size' compiler option selected. Under Debug instrument->ICD MCU configuration->Options, I set the DATASIZE_bit6 Value to 1 (the other DATASIZE bits are 0) and made ...
void sEE_ReadBuffer(uint8_t* pBuffer, uint16_t ReadAddr, uint16_t* NumByteToRead) { //__IO uint32_t timeout = 0xFFFF; __IO uint32_t timeout = 0xf00; /*!< Wait the end of last communication */ for (;timeout > 0; timeout--); /* Set the poin...
Hi all, I'm working on STM8S104kT6 mcu and I'm tring to get manage E2P.I have a couple of problems:1) EOP Bit is not set (it is always in reset state) even after a writing2) I can't lock E2P (or flash): PUL & DUL bits in FLASH_IAPSR Register are away...
Posted on June 04, 2018 at 08:05 Hello I'm use STM8L151G6 I'm trying use block programming as below: //Unlock EEPROM memory FLASH_Unlock(FLASH_MemType_Data); while (FLASH_GetFlagStatus(FLASH_FLAG_DUL) == RESET); FLASH_ProgramBlock(0,...
Posted on June 24, 2015 at 09:04Hello, I'm pretty new in STM8 programming. I'm making small project on STM8S103F3P6 microcontroller and I need to save some (27 bytes) values in EEPROM memory and reload them at every power up. I saw an example from S...
Posted on March 10, 2014 at 08:34Hello, I need help regarding writing data in EEPROM using standard block write operation. Problem is I am unable to execute the steps given in PM0051 in C++. It says that the routine for block write must be executed ...
Posted on February 03, 2014 at 12:57Hello,I am having issues writing data into EEPROM of Stm8s003K3. I am using Stm8s Discovery development board and IAR IDE.I know the algorithm of unlocking the eeprom.I have attached the code I am using. The probl...
